Minimising the global warming potential of clay based geopolymers  

Science Journals Connector (OSTI)

Abstract Production of Portland cement (PC) binders contributes substantially to global CO2 production and various bodies including the Intergovernmental Panel on Climate Change (IPCC) have identified geopolymers as alternative binders with the potential to reduce these emissions. The hypothesis of this research is to investigate whether this is a realistic proposition in the light of limited waste materials such as fly ash and ground granulated blast furnace slag commonly used as geopolymer precursors. The effect of use of natural clay minerals as alternative precursors on global warming potential (GWP) is investigated. Methods of designing mixes with the lowest possible GWP are presented and these are compared to the GWP of PC and currently available metakaolin based geopolymer binders. It is concluded that it is possible to reduce the GWP by approximately 40%, but other impacts may increase.

Global warming potential for CF[sub 4  

SciTech Connect (OSTI)

With sufficient emissions, fluorinated gases such as CF[sub 4] could contribute significantly to the concerns about global warming because they are greenhouse gases, are chemically very inert, and have long accumulation lifetimes in the atmosphere. At this time, the only significant known source of CF[sub 4] is primary aluminum smelting (Abrahamson, 1992). While current emissions are small, additional sources could make CF[sub 4] an important contribution to climate forcing in the future.

Changes in the magnitude and frequency of extreme weather associated with changes in the mean climate are likely the most serious consequence of human induced global warming. Understanding what the future portends is vital if society hopes to adapt to the very different world that awaits. In this talk, we will exploit simple extreme value theory to make predictions about the late 21st century climate. Current work on the relationship between global warming and the hurricane cycle will also be presented. The bottom line is that events that are considered rare today

Life cycle analysis of distributed concentrating solar combined heat and power: economics, global warming potential and water  

Science Journals Connector (OSTI)

We report on life cycle assessment (LCA) of the economics, global warming potential and water (both for desalination and water use in operation) for a distributed concentrating solar combined heat and power (DCS-CHP) system. Detailed simulation of system performance across 1020 sites in the US combined with a sensible cost allocation scheme informs this LCA. We forecast a levelized cost of $0.25 kWh?1 electricity and $0.03 kWh?1 thermal, for a system with a life cycle global warming potential of ~80 gCO2eq kWh?1 of electricity and ~10 gCO2eq kWh?1 thermal, sited in Oakland, California. On the basis of the economics shown for air cooling, and the fact that any combined heat and power system reduces the need for cooling while at the same time boosting the overall solar efficiency of the system, DCS-CHP compares favorably to other electric power generation systems in terms of minimization of water use in the maintenance and operation of the plant. The outlook for water desalination coupled with distributed concentrating solar combined heat and power is less favorable. At a projected cost of $1.40 m?3, water desalination with DCS-CHP would be economical and practical only in areas where water is very scarce or moderately expensive, primarily available through the informal sector, and where contaminated or salt water is easily available as feed-water. It is also interesting to note that $0.40–$1.90 m?3 is the range of water prices in the developed world, so DCS-CHP desalination systems could also be an economical solution there under some conditions.

Cosmic Rays and Global Warming  

E-Print Network [OSTI]

It has been claimed by others that observed temporal correlations of terrestrial cloud cover with `the cosmic ray intensity' are causal. The possibility arises, therefore, of a connection between cosmic rays and Global Warming. If true, the implications would be very great. We have examined this claim to look for evidence to corroborate it. So far we have not found any and so our tentative conclusions are to doubt it. Such correlations as appear are more likely to be due to the small variations in solar irradiance, which, of course, correlate with cosmic rays. We estimate that less than 15% of the 11-year cycle warming variations are due to cosmic rays and less than 2% of the warming over the last 35 years is due to this cause.

Integrated evaluation of energy use, greenhouse gas emissions and global warming potential for sugar beet (Beta vulgaris) agroecosystems in Iran  

Science Journals Connector (OSTI)

Abstract The main aim of this study was to determine and discuss the aggregate of energy use and greenhouse gas emission (CO2, N2O, and CH4) for sugar beet agroecosystems in western of Iran. For this propose data was collected by using questionnaires and face to face interview with 50 farmers. Results showed that total inputs and output energy were 49517.2 and 1095360.0 MJ ha?1, respectively. Energy use efficiency was 22.12. Total CO2, N2O and CH4 emissions due to chemical inputs were 2668.35, 22.92 and 3.49 kg, respectively. In sugar beet farms total global warming potential (GWPs) was 9847.77 kg CO2eq ha?1. In terms of CO2 equivalents, 27% of the \\{GWPs\\} come from CO2, 72% from N2O, and 1% from CH4. In this research input and output carbon were 29340.0 and 2678.6 kg C ha?1, respectively. Hence, carbon efficiency ratio was 10.95.

5 - Consequences of Global Warming  

Science Journals Connector (OSTI)

Abstract This chapter looks at different areas of risk associated with the onset of global warming. The first risk area refers to pathogens and diseases. We first discuss perspectives on disease spread, and focus on the role played by globalization and the current livestock “revolution” strongly affected by large-scale processes of urbanization. We then discuss zoonoses, or diseases that are passed between humans and other animals, and identify 11 kinds of zoonoses associated with global warming. Although not a zoonose, malaria is also discussed. Patterns of transmission associated with warming tend to be poleward, and small changes in temperature can produce large changes in disease vectors to higher latitudes. A brief presentation of the history of malaria shows how it has had a substantial effect on conflicts in the past, particularly the US Civil War (1861–1865) and World War I. It has been famously suggested that World War I ended because of the spread of Swine Flu, decimating the Axis troops and rendering many units unable to continue fighting. AIDS is presented as a contemporary example of the way in which diseases can profoundly undermine the capacity of a country to provide security and state leadership, and undercut international peacekeeping activities.

An Evaluation of the Environmental Impact of Different Commercial Supermarket Refrigeration Systems Using Low Global Warming Potential Refrigerants  

SciTech Connect (OSTI)

Commercial refrigeration systems consumed 1.21 Quads of primary energy in 2010 and are known to be a major source for refrigerant charge leakage into the environment. Thus, it is important to study the environmental impact of commercial supermarket refrigeration systems and improve their design to minimize any adverse impacts. The system s Life Cycle Climate Performance (LCCP) was presented as a comprehensive metric with the aim of calculating the equivalent mass of carbon dioxide released into the atmosphere throughout its lifetime, from construction to operation and destruction. In this paper, an open source tool for the evaluation of the LCCP of different air-conditioning and refrigeration systems is presented and used to compare the environmental impact of a typical multiplex direct expansion (DX) supermarket refrigeration systems based on three different refrigerants as follows: two hydrofluorocarbon (HFC) refrigerants (R-404A, and R-407F), and a low global warming potential (GWP) refrigerant (N-40). The comparison is performed in 8 US cities representing different climates. The hourly energy consumption of the refrigeration system, required for the calculation of the indirect emissions, is calculated using a widely used building energy modeling tool (EnergyPlus). A sensitivity analysis is performed to determine the impact of system charge and power plant emission factor on the LCCP results. Finally, we performed an uncertainty analysis to determine the uncertainty in total emissions for both R-404A and N-40 operated systems. We found that using low GWP refrigerants causes a considerable drop in the impact of uncertainty in the inputs related to direct emissions on the uncertainty of the total emissions of the system.

2 - What Is Global Warming?  

Science Journals Connector (OSTI)

Abstract In this chapter, we introduce students to the basic notion of global warming. We begin with a discussion of the historical ordinariness of global temperature swings, reviewing patterns of temperature changes across glaciations in the most recent glacial period. This is followed by a discussion of the nature of greenhouse gases, how they heat the planet, and the centrality of CO2 in the production of weather. The earth’s energy budget is presented as a chart that illustrates how various elements of the planet and its atmosphere interact to arrive at average temperatures. Following this is a discussion of human-created sources of greenhouse gases heating the planet, and here we introduce the concept of climate forcings, or external variables that are responsible for causing global temperature increases (or decreases). Primary and secondary feedbacks are shown as mechanisms in which warming, once it reaches a certain level, tends to become self-fulfilling, increasing the rate and level of heating beyond human capacity to intervene. Critical tipping points, or points at which fundamental changes in the climate will occur, are followed by a discussion of climate sensitivity, which is the assessment of the amount of temperature increase associated with increments of greenhouse gases. Finally, we ask “how hot will it get,” and close with a discussion of overall heating capacity for short- and long-term periods and a discussion of the duration of greenhouse gases, once introduced into the atmosphere.

Innovation and the dynamics of global warming  

Science Journals Connector (OSTI)

Abstract Global warming and the carbon cycle are a dynamic system with positive feedbacks. Fossil fuels are exhaustible resources. These two facts mean that innovation in clean energy technology, rather than mitigating global warming, can lead to a permanently higher temperature path. This paper explores the impact of innovation in the simplest model linking the economic theory of exhaustible resources with positive feedback dynamics in the carbon cycle.

Advertising, economic development, and global warming  

Science Journals Connector (OSTI)

Abstract Advertising is tied to global warming through an endogenous growth model. The model allows for the possibility that the environment can become a source rather than a sink for greenhouse gases. Optimal control analysis of the model shows that a feasible steady state is possible for which the environment remains a sink, and identifies a sufficient condition for such to be the case. Comparative-static analysis shows that, for sufficiently small values of steady-state anthropogenic greenhouse gas concentration, global surface temperature and advertising in steady state are negative functions of parameters that measure the damaging effects of global warming.

Second, it looks at what might be called the basic research element connecting global warming to crime: research on the relationship between crime and weather. The first item addresses the nature of research itself—how do we recognize when research is any good? There is a great deal of bad and misleading research on global warming. How do we know which is bad and which is good? The chapter begins with a discussion of three articles on Greenland melt-off, each with quite different implications, and discusses how to tell which is a legitimate research summary and which is not. It then provides a discussion of what constitutes good research generally and what one should look for when research is poorly done or intentionally misleading. For the second item, global warming and crime, we begin with a discussion of the difference between climate and weather. Much of this section is a review of Cohn’s work on temperature, crime, and violent crime. We also discuss the Ranson model, which provides a good description of the way in which crime can be modeled and predicted using data and research methods derived from the global warming literature.

Global Warming Mitigation Investments Optimized under Uncertainty Global Warming Mitigation Investments Optimized under Uncertainty Speaker(s): Hermann Held Date: July 9, 2010 - 12:00pm Location: 90-3122 Seminar Host/Point of Contact: Thomas McKone The Copenhagen Accord (2009) recognizes that 'the increase in global temperature should be below 2 degrees Celsius' (compared to pre-industrial levels, '2° target'). In recent years, energy economics have derived welfare-optimal investment streams into low-emission energy mixes and associated costs. According to our analyses, auxiliary targets that are in line with the 2° target could be achieved at relatively low costs if energy investments were triggered rather swiftly. While such analyses assume 'perfect foresight' of a benevolent 'social planner', an accompanying suite of experiments explicitly

Effects of long-term straw incorporation on the net global warming potential and the net economic benefit in a rice–wheat cropping system in China  

Science Journals Connector (OSTI)

Abstract Straw incorporation has multiple effects on greenhouse gas emissions and soil productivity. However, few studies have comprehensively evaluated the effects of long-term straw incorporation. An ongoing long-term straw incorporation experiment in a rice–wheat cropping system in China was established in 1990 and was used in the present study to evaluate the net global warming potential (NGWP) and the net economic benefit (NEB) of the straw return. The following four field treatments were included: a control (CK); N, P and K fertilization (NPK); fertilization plus a moderate rate of straw application (NPKS1); and fertilization plus a high rate of straw application (NPKS2). We calculated the increase in the soil organic carbon (SOC) and the straw-induced emissions of CH4 and N2O, which were expressed as the global warming potential (GWP) in units of CO2-equivalent (CO2-eq) at the 100-year scale. The straw-induced NEB was defined as the difference between the economic income, which was calculated by multiplying the increase in straw-induced crop grain yield by the grain price, and the economic loss was computed by multiplying the increase in straw-induced CO2-eq emissions by the carbon price. The results showed that long-term straw incorporation significantly increased the CH4 emissions and the topsoil SOC density. The GWP of the straw-induced CH4 emissions was 3.21–3.92 times that of the straw-induced SOC sequestration rate, suggesting that long-term direct straw incorporation in the rice–wheat systems worsens rather than mitigates the climate change. Additionally, continuous straw incorporation slightly enhanced the rice and wheat grain yields, contributing to the production of the NEB. We determined that under the current carbon price, ranging from 2.55 to 31.71 EUR per ton CO2-eq, the direct straw incorporation will produce a positive NEB, ranging from 156 to 658 RMB ha?1 year?1, if the grain yield prices do not fluctuate, which does not provide a significant incentive for farmers to change from their traditional direct straw incorporation pattern. Considering the other benefits that the straw application produced, such as improving soil fertility and the water retention capacity, we recommend that the government should establish an incentive for ecological compensation to encourage farmers to implement proper straw incorporation, such as composting straw under aerobic conditions before application.

Global Warming in Geologic Time  

ScienceCinema (OSTI)

The notion is pervasive in the climate science community and in the public at large that the climate impacts of fossil fuel CO2 release will only persist for a few centuries. This conclusion has no basis in theory or models of the atmosphere / ocean carbon cycle, which we review here. The largest fraction of the CO2 recovery will take place on time scales of centuries, as CO2 invades the ocean, but a significant fraction of the fossil fuel CO2, ranging in published models in the literature from 20-60%, remains airborne for a thousand years or longer. Ultimate recovery takes place on time scales of hundreds of thousands of years, a geologic longevity typically associated in public perceptions with nuclear waste. The glacial / interglacial climate cycles demonstrate that ice sheets and sea level respond dramatically to millennial-timescale changes in climate forcing. There are also potential positive feedbacks in the carbon cycle, including methane hydrates in the ocean, and peat frozen in permafrost, that are most sensitive to the long tail of the fossil fuel CO2 in the atmosphere.

Computer modeling of the global warming effect  

SciTech Connect (OSTI)

The state of knowledge of global warming will be presented and two aspects examined: observational evidence and a review of the state of computer modeling of climate change due to anthropogenic increases in greenhouse gases. Observational evidence, indeed, shows global warming, but it is difficult to prove that the changes are unequivocally due to the greenhouse-gas effect. Although observational measurements of global warming are subject to ``correction,`` researchers are showing consistent patterns in their interpretation of the data. Since the 1960s, climate scientists have been making their computer models of the climate system more realistic. Models started as atmospheric models and, through the addition of oceans, surface hydrology, and sea-ice components, they then became climate-system models. Because of computer limitations and the limited understanding of the degree of interaction of the various components, present models require substantial simplification. Nevertheless, in their present state of development climate models can reproduce most of the observed large-scale features of the real system, such as wind, temperature, precipitation, ocean current, and sea-ice distribution. The use of supercomputers to advance the spatial resolution and realism of earth-system models will also be discussed.

Combined effects of nitrogen fertilization and biochar on the net global warming potential, greenhouse gas intensity and net ecosystem economic budget in intensive vegetable agriculture in southeastern China  

Science Journals Connector (OSTI)

Abstract Field experiments were conducted to determine the effects of nitrogen (N) fertilization and biochar addition on the net global warming potential (net GWP), greenhouse gas intensity (GHGI) and net ecosystem economic budget (NEEB). These experiments were conducted in an intensive vegetable field with 4 consecutive vegetable crops in 2012 and 2013 in southeastern China. The experiment was conducted with a 32 factorial design in triplicate at N fertilizer rates of 0, 1475, 1967 kg N ha?1 and biochar rates of 0, 20, and 40 t ha?1. Although CH4 emissions were not obviously affected by N fertilization, N2O emissions increased by 27.2–116.2% and the net GWP increased by 30.6–307.2%. Consequently, the GHGI increased significantly, but vegetable yield and the NEEB did not improve. Furthermore, biochar amendments did not significantly influence CH4 emissions, but significantly decreased the N2O emissions by 1.7–25.4%, the net GWP by 89.6–700.5%, and the GHGI by 89.5–644.8%. In addition, vegetable yields significantly increased by 2.1–74.1%, which improved the NEEB. Thus, N fertilization did not increase vegetable yields or the NEEB. However, N fertilization did increase the net GWP and GHGI. In contrast, biochar additions resulted in lower N2O emissions and net GWP and GHGI, but increased vegetable yield and the NEEB in the intensive vegetable production system. Therefore, appropriate biochar amendment should be studied to combat changing climate and to improve the economic profits of vegetable production.

The effect of fertilizer practices on N balance and global warming potential of maize–soybean–wheat rotations in Northeastern China  

Science Journals Connector (OSTI)

Abstract Long-term agronomic studies are useful to determine cropping system nitrogen (N) use efficiency and the fate of applied fertilizers. We used a subtractive fertilizer experiment incorporating N, phosphorous (P), potassium (K) and swine manure to determine long-term changes in grain yield, soil organic carbon (SOC), total soil nitrogen (N), as well as carbon dioxide (CO2) and nitrous oxide (N2O) emissions. The experiment was conducted on a 22-year maize–soybean–wheat rotation in Northeastern China. Crop residues were removed for cooking fuel and forage according to local practices. Five fertilizer treatments were applied annually: control (no fertilizer), NK, NP, NPK, and NPKOM (N, P, K and manure). The NPKOM treatment increased SOC and total soil N by 4.59 and 0.45 Mg ha?1, respectively. In contrast, SOC decreased by 10.6 and 6.64 Mg ha?1 in the control and NK treatments, respectively. The NPKOM treatment had an average of 2.9 times more N2O emissions than the other fertilizer treatments. The cropping system balances for N and SOC, together with fuel use for farming practices and manure handling, were used to calculate the global warming potential (GWP) of the different fertilizer treatments. Due to SOC sequestration, the GWP of the NPKOM treatment (6.77 Mg C equivalent ha?1) was significantly lower than that of both the control (14.4 Mg C equivalent ha?1) and the NK treatment (12.8 Mg C equivalent ha?1). The results suggest that in rainfed agricultural systems in Northeastern China, the application of manure supplemented with NPK can simultaneously achieve higher grain yield and lower GWP compared to mineral fertilizers alone.

Forestry and global warming: the physical and policy linkages  

Science Journals Connector (OSTI)

The potential for biotically mitigating global warming is receiving a great deal of policy and technical attention around the world. Elements of the political community are drawn to the notion that land?use patterns can be modified more easily than energy consumption patterns and some modelers suggest that the potential for storing carbon in terrestrial ecosystems is very large. Most work to date however uses only physical criteria in estimating how much land might be available for reforestation. Accounting for social and economic constraints is much more difficult resulting in daunting uncertainty about what could actually be accomplished. Furthermore our relative ignorance of the functioning of the global carbon cycle makes attempting to manipulate it for human purposes questionable at best. Nevertheless there are many reasons besides global warming to pursue a radical restructuring of land?use patterns around the world. Such a restructuring should be undertaken in conjunction with many other measures to slow global warming most immediately in the energy sector.

Surface reflectance and conversion efficiency dependence of technologies for mitigating global warming  

Science Journals Connector (OSTI)

A means of assessing the relative impact of different renewable energy technologies on global warming has been developed. All power plants emit thermal energy to the atmosphere. Fossil fuel power plants also emit CO2 which accumulates in the atmosphere and provides an indirect increase in global warming via the greenhouse effect. A fossil fuel power plant may operate for some time before the global warming due to its CO2 emission exceeds the warming due to its direct heat emission. When a renewable energy power plant is deployed instead of a fossil fuel power plant there may be a significant time delay before the direct global warming effect is less than the combined direct and indirect global warming effect from an equivalent output coal fired plant – the “business as usual” case. Simple expressions are derived to calculate global temperature change as a function of ground reflectance and conversion efficiency for various types of fossil fuelled and renewable energy power plants. These expressions are used to assess the global warming mitigation potential of some proposed Australian renewable energy projects. The application of the expressions is extended to evaluate the deployment in Australia of current and new geo-engineering and carbon sequestration solutions to mitigate global warming. Principal findings are that warming mitigation depends strongly on the solar to electric conversion efficiency of renewable technologies, geo-engineering projects may offer more economic mitigation than renewable energy projects and the mitigation potential of reforestation projects depends strongly on the location of the projects.

Coastal regions have a high social, economical and environmental importance. Due to this importance the sea level fluctuations can have many bad consequences. In this research the correlation between the increasing trend of temperature in coastal stations due to Global Warming and the Caspian Sea level has been established. The Caspian Sea level data has been received from the Jason-1 satellite. It was resulted that the monthly correlation between the temperature and sea level is high and also positive and almost the same for all the stations. But the yearly correlation was negative. It means that the sea level has decreased by the increase in temperature.

Lacis NASA Goddard Institute for Space Studies Accelerated melting of Greenland ice is a clear indication that consequences of global warming are real and impending. The underlying causes of global warming are well enough understood, but the necessary reduction of greenhouse gases to prevent irreversible climate change is unlikely to happen before the point of no return is reached. To reverse the impending sea level rise, geoengineering counter- measures may be required to counter the current global energy imbalance due to global warming. Of the many proposed remedies, deploying aerosols within the stratosphere offers realistic prospects. Sulfur injections in the lower stratosphere would have the cooling effect of naturally occurring volcanic aerosols. Soot at

11 - Security Issues and Global Warming  

Science Journals Connector (OSTI)

Abstract This chapter begins with a discussion of the increasing empowerment of nonstate actors to challenge nation-states for commerce and security. One of the central trends is the operational coordination of organized crime and terrorist entities. They tend to share the same pipelines and at times some of the same personnel since both have a need for similar specialized skills. We witness the emergence of the third generation of guerillas, described as leaderless or horizontal in structure, global, and highly adaptable to urban areas. Crevald’s position on guerilla wars is discussed—he asserted that states can never effectively combat guerilla wars. We then discuss the many ways in which transnational criminal organizations and terrorists are working together in the current era. From there, we assess the roles of criminalized states and “black holes,” geographical areas not controlled by state-based security entities. We discuss how global warming works to enhance the strengths of nonstate actors, while at the same time undermining or limiting state security. This chapter closes with a discussion of the security changes likely to be associated with an ice-free Arctic Ocean. We look at changes already occurring, and assess the roles played by the United States, Canada, Russia, and China. All are in exploration stages for previously inaccessible resources, and most are increasing their military presence across the region.

4 - Modeling the Relationship Between Global Warming, Violence, and Crime  

Science Journals Connector (OSTI)

Abstract One of the challenges of global warming research to the social sciences is that physical science research modalities are different. Consequently, efforts to tie it to the social sciences, particularly those related to violence and crime, are difficult to develop. This chapter looks at two models to assess the linkages between global warming and crime. The first, the Homer-Dixon model, uses a resource scarcity model to look at these linkages. According to the Homer-Dixon model, many aspects of global warming produce scarcities such as food shortages, ranch and farmland loss, and clean-water shortages. By tracing the indirect effects of scarcities through intervening variables of migration and state hardening, the model allows us to see various kinds of crime and violence that might happen under global warming conditions. The second model is the Agnew model, developed to assess theoretical linkages between crime and global warming, primarily focusing on social disorganization and strain perspectives. The second model fills a critical shortcoming in the first model; it provides a nuanced notion of crime and crime theory. Hence, it provides a needed “back end” of crime outcomes to tie into the Homer-Dixon model. Also, we discuss the way in which many dimensions of global warming can be modeled relatively straightforwardly into a routine activities perspective, where the social and economic disruptions caused by global warming give rise to new patterns of human activity and, consequently, new patterns of criminal and predatory activities.

R&D for technology to solve global warming  

Science Journals Connector (OSTI)

Global warming is a problem in which the combustion of coal, oil, and other fossil fuels causes the atmospheric concentrations of greenhouse gases, such as carbon dioxide (CO2), to increase. This results in mounting global air temperatures that lead to climatic change. Specifically, global warming will cause a rise in sea levels, changes in the rain-fall patterns, and other problems. In order to secure the route to solutions for global warming that requires new responses in ways that are compatible with economic growth, it is essential to achieve breakthroughs with innovative technologies. In addition to energ-related R&D, also important are R&D for CO2 absorption and fixation for fundamental solution to global warming. Japan has started the development of innovative environmental technologies, such as technologies for CO2 fixation and utilization.

Global warming and oil spills could cool shoaling reefs  

SciTech Connect (OSTI)

High water temperature generated on reef flats have been implicated as one of the factors determining the ecological patterns and structural morphologies peculiar to shoaling reefs. In approximately ten years of water temperature and water level data from a shoaling reef flat at Punta Galeta (Caribbean Panama), water temperatures were dependent on water levels. Water temperatures ranged up to 38[degrees]C when daily minimum water depths over the reef crest were < 12 cm, but never exceeded 30[degrees]C when the minimum water levels were > 12 cm. If conservative predictions of sea level rise caused by global warming are correct, normal vertical accretion rates of the reef flat could keep pace with rising sea level until the middle of the next century; after that the occurrence of high water temperatures would be rapidly reduced. However, damage from an oil spill at Punta Galeta in 1986 was concentrated at the seaward margin of the reef flat, where biogenic processes control the overall vertical accretion of the reef platform. By slowing rates of vertical accretion, oil impact could potentially accelerate the effects of global warming on the ecology and morphology of the reef.

Global warming description using Daisyworld model with greenhouse gases  

Science Journals Connector (OSTI)

Abstract Daisyworld is an archetypal model of the earth that is able to describe the global regulation that can emerge from the interaction between life and environment. This article proposes a model based on the original Daisyworld considering greenhouse gases emission and absorption, allowing the description of the global warming phenomenon. Global and local analyses are discussed evaluating the influence of greenhouse gases in the planet dynamics. Numerical simulations are carried out showing the general qualitative behavior of the Daisyworld for different scenarios that includes solar luminosity variations and greenhouse gases effect. Nonlinear dynamics perspective is of concern discussing a way that helps the comprehension of the global warming phenomenon.

Physical aspects of the greenhouse effect and global warming  

Science Journals Connector (OSTI)

According to the simplest model of the earth’s radiative balance global warming will occur with certainty as humankind increases its production and consumption of nonsolar energy. This prediction is revisited using a broader model that allows the greenhouse effect to be considered. The new model predicts a global warming of ?T E =(114? K )? where ? is the rate of surface energy release in units of the average incident solar radiation 342? W?m ?2 and ?T E is the average temperature rise at the earth’s surface. Present values of these quantities excluding geothermal sources are ?=0.69×10 ?4 and ?T E =7.9? mK . The model assigns a small number of optical parameters to the atmosphere and surface and qualifies the simple warming prediction: It is rigorous only if parameters other than ? are unchanged. The model is not complex and should serve as an aid to an elementary understanding of global warming.

SciTech Connect (OSTI)

This document provides methods to account for the different effects of different gases on the atmosphere. It discusses the rationale and uses for simplified measures to represent human-related effects on climate and provides a brief introduction to a major index, the global warming potential (GWP) index. Appendix 7.A analyzes the science underlying the development of indices for concerns about climate, which is still evolving, evaluates the usefulness of currently available indices, and presents the state of the art for numerical indices and their uncertainties. For concerns about climate, the Intergovernmental Panel on Climate Change (IPCC) has been instrumental in examining relative indices for comparing the radiative influences of greenhouse gases. The IPCC developed the concept of GWPs to provide a simple representation of the relative effects on climate resulting from a unit mass emission of a greenhouse gas. Alternative measures and variations on the definition of GWPs have also been considered and reported.

Global warming and end-use efficiency implications of replacing CFCs  

SciTech Connect (OSTI)

The direct contribution of CFCs to calculated global warming has been recognized for some time. As a result of the international agreement to phase out CFCs due to stratospheric ozone and the ensuing search for suitable alternatives, there has recently been increased attention on the DIRECT global warming potential (GWP) of the fluorocarbon alternatives as greenhouse gases. However, to date there has been little focus on the INDIRECT global warming effect arising from end-use efficiency changes and associated CO{sub 2} emissions. A study being conducted at Oak Ridge National Laboratory (ORNL) addresses this combined or total global warming impact of viable options to replace CFCs in their major energy-related applications. This paper reviews selected results for air-conditioning, refrigeration, and heat pump applications. The analysis indicates that the CFC user industries have made substantial progress in approaching near-equal energy efficiency with the HCFC/HFC alternative refrigerants. The findings also bring into question the relative importance of the DIRECT (chemical-related) effect in many applications. Replacing CFCs is an important step in reducing the total global warming impact, and at present the HCFC and HFCS appear to offer the best efficiency and lowest total impact of options available in the relatively short time period required for the transition away from CFCs.

A prairie perspective on global warming and climate change  

Science Journals Connector (OSTI)

The Great Plains blankets eight states. It is dotted with oil patches, public utilities, farms, ranches, feed lots, meat-packing plants, medium size cities, military bases and tiny towns feeding on agricultural activity. The question is: what can leaders do for a desperate and aging population in a global warming environment to bring full employment to the region. This paper explores opportunities to capitalise upon environmentally friendly farming practices and agricultural waste to produce jobs, money, commercial opportunities, marketable sod, fertilisers, methane, electricity and securities (from the Chicago Climate Exchange) as answers for this question. The paper recounts the use of man made wetlands to sequester CO2; by-products from coal fired power plants; landfill methane; methane digesters and soil carbon projects to arrest heat and contribute to the campaign against global warming.

The British coal global warming R&D programme  

Science Journals Connector (OSTI)

The threat of possible global warming is sufficient to warrant ‘least regrets’ measures to reduce emissions of greenhouse gases and investigation of fallback options, such as carbon dioxide removal from coal-fired power plants. The Global Warming R&D Programme is investigating carbon dioxide removal options, sometimes called ‘Low CO2 Power Generation’. An assessment programme has estimated the thermal efficiency of a number of process schemes and concluded that gasification based systems, with the addition of a CO shift reactor and CO2 scrubbers or a membrane gas separator, provide promising approaches. A clean hydrogen fuel would be fired in a gas turbine and 90% of the CO2 removed and exported as a liquid stream for storage in exhausted oil or gas fields. Costs of such power plants are now being explored and a collaborative programme is commencing with membrane developers, with the aim of developing and testing membranes for this duty. The paper outlines the background and describes preparation for experimental work using CO2/H2 separating membranes.

Combating global warming via non-fossil fuel energy options  

Science Journals Connector (OSTI)

Non-fossil fuel energy options can help reduce or eliminate the emissions of greenhouse gases and are needed to combat climate change. Three distinct ways in which non-fossil fuel options can be used in society are examined here: the capture/production of non-fossil fuel energy sources, their conversion into appropriate energy carriers and increased efficiency throughout the life cycle. Non-fossil fuel energy sources are insufficient to avoid global warming in that they are not necessarily readily utilisable in their natural forms. Hydrogen energy systems are needed to facilitate the use of non-fossil fuels by converting them to two main classes of energy carriers: hydrogen (and hydrogen-derived fuels) and electricity. High efficiency is needed to allow the greatest benefits to be attained from energy options in terms of climate change and other factors. A case study is considered involving the production of hydrogen from non-fossil energy sources via thermochemical water decomposition. Thermochemical water decomposition provides a realistic future non-fossil fuel energy option, which can be driven by non-fossil energy sources (particularly nuclear or solar energy) and help combat global warming.

Elementary physical reasoning seems to leave it inevitable that global warming would increase the variability of the weather. The first two terms in an approximation to the global entropy are used to show that global warming has increased the free energy available to drive the weather, and that the variance of the weather should increase correspondingly.

Global warming and transport in Brazil - ethanol alternative  

Science Journals Connector (OSTI)

This paper deals with the risk of global warming as intensified by the carbon dioxide (CO2) emissions of the transport sector, particularly in gasoline-powered vehicles in Brazil. Car ownership and use are increasing rapidly partly because of very poor public transport quality, which, in turn, is causing higher emission levels of CO2. In this connection, the use of ethanol in Brazil for the transport sector may prove to be an important alternative, furthering the efforts to stabilise the actual level of gases in the atmosphere. The energy derived from biomass, and in this case, from a renewable, ''clean'' source, i.e., from sugar-cane, has the unquestionable advantage of permitting the almost complete reabsorption of CO2 emitted through the combustion of fuel alcohol. This closed cycle allows, in principle, the increase of the energy supply, essential for economic development, with fewer hazards to the environment.

Effective thermal conduction model for estimating global warming  

Science Journals Connector (OSTI)

This paper presents a simple way to approximate the dependence of the global mean air temperature at Earth’s surface on the atmospheric concentration of carbon dioxide. It treats the atmosphere as a blanket the effective thermal conductivity of which is a decreasing function of the amount of CO 2 present and does not involve the details of energy transport. The only data required are the CO 2 concentrations at the middle of the nineteenth and the end of the twentieth centuries and the shift in temperature that has occurred over that time. This elementary phenomenological energy-balance approach is well suited for undergraduate physics courses to illustrate thermal conduction and radiation by way of the very interesting and critically important example of greenhouse warming of Earth.

Nuclear energy conversion systems for arresting global warming  

Science Journals Connector (OSTI)

Presently the global warming by CO2 emission from fossil fuel burning is becoming a serious issue. Especially, coal is the worse fossil fuel, because it emits the largest amount of CO2 per unit amount of heat generation. There seem to be two ways of reducing substantial CO2 emission rate of coal; they are, reforming coal to synthesis fuel with less CO2 emission and removing CO2 from flue gas of coal fired power station after burning coal. Present paper proposes two nuclear heat application systems which reform coal to methanol and four systems which produce chemical products or gasoline with CO2 collected from flue gas of coal fired power stations, as future options for reducing CO2 emission from coal. Advantage and disadvantage of the proposed systems are discussed.

Future-oriented women will pay to reduce global warming: Mediation via political orientation, environmental values, and belief in global warming  

Science Journals Connector (OSTI)

Abstract The present work addresses calls to clarify the role of gender in climate change mitigation and adaptation by testing a theoretical model linking gender and concern with future and immediate consequences to mitigation actions through political orientation, environmental values, and belief in global warming (gender × time orientation ? liberal political orientation ? environmental values ? belief in global warming ? willingness to pay to reduce global warming). Drawing on a sample of 299 U.S. residents, structural equation modeling and bootstrapped indirect effects testing revealed support for the model. Interaction analyses further revealed that women scored higher than men on model variables among respondents who routinely consider the future consequences of their actions, but the gender difference was reversed among those low in concern with future consequences (on liberal political orientation and willingness to pay to reduce global warming). Practical and theoretical implications are considered.

Heart rate change and attitudes to global warming: A conceptual replication of the visceral fit mechanism  

Science Journals Connector (OSTI)

Abstract Visceral fit effects occur when a physical state (e.g., warmth) increases the plausibility of future related states (e.g., global warming). We attempted to conceptually replicate such effects by investigating whether belief in global warming is influenced by a change in heart rate, which is linked to body warmth. In four studies, participants' heart rates were varied via mental manipulation or physical exercise. In three of the studies, increased heart rate was associated with greater self-reported belief that global warming was occurring. Across all studies, the association between heart rate and self-reported belief in global warming was small in statistical effect size and very small in absolute terms. We suggest that the effects of incidental cues are interesting because such factors should not influence global warming beliefs at all, but the small absolute size of the effects means that situational cues are unlikely to alter a person's stance on climate change.

Chapter Thirty-Six - The Implications of Global Warming and Climate Change on Waterborne Diseases  

Science Journals Connector (OSTI)

Abstract The distribution of pathogens and the incidence of waterborne disease outbreaks are closely linked to environmental and climatic conditions. Global climate change will affect the hydrological cycle in many different ways that will influence waterborne pathogen survival, infectivity and distribution. These changes include frequency and intensity of heavy rainfall events leading to higher surface runoff and flooding, droughts, increased temperatures and sea level rise. Indirectly, this will impact on the effectiveness of traditional infrastructural and the barrier approach to pathogen control on which water industry has evolved and now relies. Climate change will also result in an alteration in the behaviour of populations and test their ability to cope with changes in risk from infection and possible failures in the barriers that protect them from pathogens. The effect of climate change on the risk from waterborne diseases will differ between tropical and temperate areas, and developed and developing countries. Those countries with a well-developed water and wastewater treatment infrastructure will be least affected. The key to overcoming these problems is an awareness of the potential risks to pathogen distribution and infectivity caused by global warming and the implementation of an integrated approach to pathogen safety through the implementation of water security and water safety plans. The United Nations Millennium Development Goal to halve the number of people without sustainable access to safe drinking water and basic sanitation by 2015 is unlikely to be achieved. Global warming is increasing the number of people falling into this category each year, as well as making it far more difficult to achieve the vital goal. Disinfection will remain the major technique of ensuring drinking water is free from waterborne microorganisms, but it must be seen as part of a larger integrated approach to water resource protection which will become increasingly difficult as global warming continues to create uncertainties in our climate.

Global warming impacts of ozone-safe refrigerants and refrigeration, heating, and air-conditioning technologies  

SciTech Connect (OSTI)

International agreements mandate the phase-out of many chlorine containing compounds that are used as the working fluid in refrigeration, air-conditioning, and heating equipment. Many of the chemical compounds that have been proposed, and are being used in place of the class of refrigerants eliminated by the Montreal Protocol are now being questioned because of their possible contributions to global warming. Natural refrigerants are put forth as inherently superior to manufactured refrigerants because they have very low or zero global warming potentials (GWPs). Questions are being raised about whether or not these manufactured refrigerants, primarily hydrofluorocarbons (HFCs), should be regulated and perhaps phased out in much the same manner as CFCs and HCFCs. Several of the major applications of refrigerants are examined in this paper and the results of an analysis of their contributions to greenhouse warming are presented. Supermarket refrigeration is shown to be an application where alternative technologies have the potential to reduce emissions of greenhouse gases (GHG) significantly with no clear advantage to either natural or HFC refrigerants. Mixed results are presented for automobile air conditioners with opportunities to reduce GHG emissions dependent on climate and comfort criteria. GHG emissions for hermetic and factory built systems (i.e. household refrigerators/freezers, unitary equipment, chillers) are shown to be dominated by energy use with much greater potential for reduction through efficiency improvements than by selection of refrigerant. The results for refrigerators also illustrate that hydrocarbon and carbon dioxide blown foam insulation have lower overall effects on GHG emissions than HFC blown foams at the cost of increased energy use.

In the latter case, temperatures rise by less than 2°C (3.6°F) across nearly all of Earth's populated areas (the bottom panel shows warming averted). However, unchecked emissions could lead to warming of 3°C (5.4°F) or more across parts of Europe, Asia, North America, and Australia. (Image: Geophysical

Natural gas and efficient technologies: A response to global warming  

SciTech Connect (OSTI)

It has become recognized by the international scientific community that global warming due to fossil fuel energy buildup of greenhouse CO{sub 2} in the atmosphere is a real environmental problem. Worldwide agreement has also been reached to reduce CO{sub 2} emissions. A leading approach to reducing CO{sub 2} emissions is to utilize hydrogen-rich fuels and improve the efficiency of conversion in the power generation, transportation and heating sectors of the economy. In this report, natural gas, having the highest hydrogen content of all the fossil fuels, can have an important impact in reducing CO{sub 2} emissions. This paper explores natural gas and improved conversion systems for supplying energy to all three sectors of the economy. The improved technologies include combined cycle for power generation, the Carnol system for methanol production for the transportation sector and fuel cells for both power generation and transportation use. The reduction in CO{sub 2} from current emissions range from 13% when natural gas is substituted for gasoline in the transportation sector to 45% when substituting methanol produced by the Carnol systems (hydrogen from thermal decomposition of methane reacting with CO{sub 2} from coal-fired power plants) used in the transportation sector. CO{sub 2} reductions exceeding 60% can be achieved by using natural gas in combined cycle for power generation and Carnol methanol in the transportation sector and would, thus, stabilize CO{sub 2} concentration in the atmosphere predicted to avoid undue climate change effects. It is estimated that the total fossil fuel energy bill in the US can be reduced by over 40% from the current fuel bill. This also allows a doubling in the unit cost for natural gas if the current energy bill is maintained. Estimates of the total net incremental replacement capital cost for completing the new improved equipment is not more than that which will have to be spent to replace the existing equipment conducting business as usual.

Global warming implications of non-fluorocarbon technologies as CFC replacements  

SciTech Connect (OSTI)

Many technologies could be developed for use in place of conventional compression systems for refrigeration and air conditioning. Comparisons of the global warming impacts using TEWI (Total Equivalent Warming Impact) can be used to identify alternatives that have the potential for lower environmental impacts than electric-driven vapor compression systems using HCFCs and HFCs. Some options, such as secondary heat transfer loops in commercial refrigeration systems to reduce refrigerant charge and emission rates, could be useful in reducing the losses of refrigerants to the atmosphere. Use of ammonia instead of a fluorocarbon in a system with a secondary loop offers only a small potential for decreasing TEWI, and this may not warrant the increased complexity and risks of using ammonia in a retail sales environment. A few technologies, such as adsorption heat pumps, have efficiency levels that show reduced TEWI levels compared to conventional and state of the art compression systems, and further development could lead to an even more favorable comparison. Health and safety risks of the alternative technologies and the materials they employ must also be considered.

SciTech Connect (OSTI)

This book is published to tie in with a documentary film of the same name. Both the book and film were inspired by a series of multimedia presentations on global warming that the author created and delivers to groups around the world. With this book, Gore, brings together leading-edge research from top scientists around the world; photographs, charts, and other illustrations; and personal anecdotes and observations to document the fast pace and wide scope of global warming. He presents, with alarming clarity and conclusiveness, and with humor, too, that the fact of global warming is not in question and that its consequences for the world we live in will be disastrous if left unchecked.

Marine methane cycle simulations for the period of early global warming  

SciTech Connect (OSTI)

Geochemical environments, fates, and effects are modeled for methane released into seawater by the decomposition of climate-sensitive clathrates. A contemporary global background cycle is first constructed, within the framework of the Parallel Ocean Program. Input from organics in the upper thermocline is related to oxygen levels, and microbial consumption is parameterized from available rate measurements. Seepage into bottom layers is then superimposed, representing typical seabed fluid flow. The resulting CH{sub 4} distribution is validated against surface saturation ratios, vertical sections, and slope plume studies. Injections of clathrate-derived methane are explored by distributing a small number of point sources around the Arctic continental shelf, where stocks are extensive and susceptible to instability during the first few decades of global warming. Isolated bottom cells are assigned dissolved gas fluxes from porous-media simulation. Given the present bulk removal pattern, methane does not penetrate far from emission sites. Accumulated effects, however, spread to the regional scale following the modeled current system. Both hypoxification and acidification are documented. Sensitivity studies illustrate a potential for material restrictions to broaden the perturbations, since methanotrophic consumers require nutrients and trace metals. When such factors are considered, methane buildup within the Arctic basin is enhanced. However, freshened polar surface waters act as a barrier to atmospheric transfer, diverting products into the deep return flow. Uncertainties in the logic and calculations are enumerated including those inherent in high-latitude clathrate abundance, buoyant effluent rise through the column, representation of the general circulation, and bacterial growth kinetics.

Hydrologic sensitivities of the Sacramento-San Joaquin River basin, California, to global warming  

SciTech Connect (OSTI)

The hydrologic sensitivities of four medium-sized mountainous catchments in the Sacramento and San Joaquin River basins to long-term global warming were analyzed. The hydrologic response of these catchments, all of which are dominated by spring snowmelt runoff, were simulated by the coupling of the snowmelt and the soil moisture accounting models of the U.S. National Weather Service River Forecast System. In all four catchments the global warming pattern, which was indexed to CO{sub 2} doubling scenarios simulated by three (global) general circulation models, produced a major seasonal shift in the snow accumulation pattern. Under the alternative climate scenarios more winter precipitation fell as rain instead of snow, and winter runoff increased while spring snowmelt runoff decreased. In addition, large increases in the annual flood maxima were simulated, primarily due to an increase in rain-on-snow events, with the time of occurrence of many large floods shifting from spring to winter.

Can nuclear energy contribute to slowing global warming?  

Science Journals Connector (OSTI)

An important source of greenhouse gases, in particular CO2, is fossil fuel combustion for energy applications. Since nuclear power is an energy source that does not produce CO2, the question has been raised as to what part it may play in mitigating the greenhouse effect. This article examines that question. In doing so it recognizes, however, that we cannot deal with one environmental problem in isolation. The article, therefore, seeks to identify the range of factors which need to be assessed for a balanced evaluation of nuclear energy's potential role.

Global warming and South Indian monsoon rainfall—lessons from the Mid-Miocene  

Science Journals Connector (OSTI)

Precipitation over India is driven by the Indian monsoon. Although changes in this atmospheric circulation are caused by the differential seasonal diabatic heating of Asia and the Indo-Pacific Ocean, it is so far unknown how global warming influences the monsoon rainfalls regionally. Herein, we present a Miocene pollen flora as the first direct proxy for monsoon over southern India during the Middle Miocene Climate Optimum. To identify climatic key parameters, such as mean annual temperature, warmest month temperature, coldest month temperature, mean annual precipitation, mean precipitation during the driest month, mean precipitation during the wettest month and mean precipitation during the warmest month the Coexistence Approach is applied. Irrespective of a ~ 3–4 °C higher global temperature during the Middle Miocene Climate Optimum, the results indicate a modern-like monsoonal precipitation pattern contrasting marine proxies which point to a strong decline of Indian monsoon in the Himalaya at this time. Therefore, the strength of monsoon rainfall in tropical India appears neither to be related to global warming nor to be linked with the atmospheric conditions over the Tibetan Plateau. For the future it implies that increased global warming does not necessarily entail changes in the South Indian monsoon rainfall.

Global warming mitigation and renewable energy policy development from the Kyoto Protocol to the Copenhagen Accord—A comment  

Science Journals Connector (OSTI)

Global warming is a grave environmental issue that has caught the attention of the globe. Due to the consequences of global warming, UNFCCC has established the Kyoto Protocol and the Copenhagen Accord as measures of combating climate change due to the emission of greenhouse gases. It has been three years since the first commitment period of the Kyoto Protocol and the Copenhagen Accord was just newly established. Therefore, there is a necessity to evaluate the performance of the Kyoto Protocol and to comment upon the Copenhagen Accord in its contributions toward climate change mitigation. Major greenhouse gas (GHG) emitters who are among the Kyoto Protocol ratifying developed nations exhibit the potential to achieve the desired Kyoto pledges through the aid of Clean Development Mechanisms (mainly from using renewable energy), as proposed in the Kyoto Protocol. However, the nullifying effects from non-ratified major emitters like the US and ratified but still developing countries have difficulties in adhering to the Kyoto Protocol. The Copenhagen Accord, on the other hand, is considered to be less ambitious and provides limited financial aid through the Copenhagen Green Climate Fund. The formulation of such a document indicates that modern societies continues to waste time in negotiations that emphasize on individual economic and political advantages, rather than taking into account true global considerations. It raises questions regarding how much time is needed before we decide to fully commit to the effective and collective efforts of climate change mitigation.

The Role of Subtropical Irreversible PV Mixing in the Zonal Mean Circulation Response to Global Warming-like Thermal Forcing  

SciTech Connect (OSTI)

The atmospheric circulation response to the global warming-like tropical upper tropospheric heating is revisited using a dry atmospheric general circulation model (AGCM) in light of a new diagnostics based on the concept of finite-amplitude wave activity (FAWA) on equivalent latitude. For a given tropical heating profile, the linear Wentzel-Kramers-Brillouin (WKB) wave refraction analysis sometimes gives a very different and even opposite prediction of the eddy momentum flux response to that of the actual full model simulation, exposing the limitation of the traditional linear approach in understanding the full dynamics of the atmospheric response under global warming. The implementation of the FAWA diagnostics reveals that in response to the upper tropospheric heating, effective diffusivity, a measure of the mixing efficiency, increases and advances upward and poleward in the subtropics and the resultant enhancement and the poleward encroachment of eddy potential vorticity mixing leads to a poleward displaced potential vorticity (PV) gradient peak in the upper troposphere. The anomalous eddy PV flux, in balance with the PV dissipation, gives rise to a poleward shift in the eddy-driven jet and eddy-driven mean meridional circulation. Sensitivity experiments show that these irreversible dissipation processes in the upper troposphere are robust, regardless of the width of the tropical heating.

Role of global warming on the statistics of record-breaking temperatures  

Science Journals Connector (OSTI)

We theoretically study the statistics of record-breaking daily temperatures and validate these predictions using both Monte Carlo simulations and 126years of available data from the city of Philadelphia. Using extreme statistics, we derive the number and the magnitude of record temperature events, based on the observed Gaussian daily temperature distribution in Philadelphia, as a function of the number of years of observation. We then consider the case of global warming, where the mean temperature systematically increases with time. Over the 126-year time range of observations, we argue that the current warming rate is insufficient to measurably influence the frequency of record temperature events, a conclusion that is supported by numerical simulations and by the Philadelphia data. We also study the role of correlations between temperatures on successive days and find that they do not affect the frequency or magnitude of record temperature events.

Albedo control as an effective strategy to tackle Global Warming: A case study  

Science Journals Connector (OSTI)

Abstract Recent research developments focused on Climate Change issue aimed at achieving Kyoto targets. In this context, an innovative methodology (officially recognized by WEC in 2009) is proposed to mitigate Global Warming by artificially enhancing earth’s Albedo. Such a methodology allows to quantify the maximum environmental benefit achievable through the installation of Albedo control technologies, as a function of the geographical features of the installation site, local meteorological conditions, radiative properties, tilt angle, and orientation of the surfaces. This benefit is directly quantified in terms of \\{CO2eq\\} offset. Albedo control can be an effective mitigation strategy by means of three synergistic effects: a direct contribution towards Global Warming mitigation produced by an enhanced reflection to the space of the shortwave incident radiation; the indirect contribution from energy saving in buildings with high Albedo envelopes; the indirect contribution from the mitigation of Urban Heat Island phenomenon. Since the effectiveness of Albedo control is mostly relevant in Mediterranean area, for both climate conditions and historical-architectural heritage, this work presents procedures and findings of the ABCD project (Albedo, Building green, Control of Global Warming and Desertification) concluded in 2012, funded by the Italian Ministry for the Environment. A description of the analytic model is also presented. The paper focuses on the application of the methodology to a Tunisian factory site, showing that approximately 16,000 tCO2eq could be offset in 30 years with the installation of about 115,000 m2 of high-reflective surfaces. Finally, a tradable value (ETS carbon credits) for Albedo control technologies is proposed.

The political economy of a biomass energy response to global warming (GREENS)  

Science Journals Connector (OSTI)

GREENS (Global Redevelopment with Energy Environment Sustainability) is a concept that provides a response to global warming which integrates the technological, economic and political aspects of the problem. Technological and economic aspects are discussed elsewhere. The political aspects involve a context in which growth in energy use is foreseen mostly in the 'South', where the Third World Debt burden is perceived to be unfair. However, the 'South' provides promising venues for biomass production and GREENS offers the prospect of biomass technology transfer in support of progress in newly developing countries, per contra alternative responses which hinder the 'South's' development. But countries like Russia, China and India (dubbed 'East' countries) with developed fossil fuel systems, present a significant burden upon the 'North' until future technologies become available and/or the 'East's' economic progress fits it to share the cost of biomass substitution.

Coal: Prospects in the Twenty-First Century: Exhaustion Trumped by Global Warming?  

Science Journals Connector (OSTI)

Abstract There has been a great transformation in the nature and location of use of coal, as well as in the location of its production. China and India have emerged as the major producers and consumers of coal. Electricity generation has become its main use. Interest in coal as a replacement for depleting oil and natural gas resources remains, but at a greatly diminished level. Fears of global warming have supplemented traditional concerns about pollution from coal. These and other concerns have led to extensive policies regulating the production and use of coal. The United States has programs affecting labor standards in coal mining, reclamation of mined land, leasing of coal resources on federally owned land, and air and water pollution. Air pollution controls try to directly control pollution through standards on the allowable pollutant content in the atmosphere and to indirectly regulate it by setting emission standards at individual pollution sources. These complex and overlapping regulations are proving difficult to design and implement. As global warming control must be worldwide, its achievement involves daunting implementation barriers.

Potential enhancement of warm X-ray dose from a reflexing bremsstrahlung diode  

SciTech Connect (OSTI)

The potential for generating intense bursts of warm x rays (20 to 60 keV) using electron reflexing diodes on pulsed-power accelerators is evaluated with the TIGER Monte Carlo code, showing that hundreds of kilojoules of warm x rays can be generated under idealized conditions, for a Jupiter (60-MA, 5-MV, 100-ns) class accelerator. The calculations are compared with data from Gamble-II experiments and applied to two suggested Jupiter diode configurations. If the simultaneous irradiation from the high-energy tail of the bremsstrahlung, which accompanies the warm x rays, is a concern then the reflexing technique is shown to be limited to the irradiation of targets thinner than {approximately}400 {mu}m for low-Z targets like aluminum and thinner than {approximately}5 {mu}m for high-Z targets like gold.

Energy and global warming impacts of next generation refrigeration and air conditioning technologies  

SciTech Connect (OSTI)

Significant developments have occurred in hydrofluorocarbon (HFC) and the application of ammonia and hydrocarbons as refrigerant working fluids since the original TEWI (Total Equivalent Warming Impact) report in 1991. System operating and performance data on alternative refrigerants and refrigeration technologies justify and updated evaluation of these new alternative refrigerants and competing technologies in well-characterized applications. Analytical and experimental results are used to show quantitative comparisons between HFCS, HFC blends, hydrocarbons, and ammonia, used as refrigerants. An objective evaluation is presented for commercial and near commercial non-CFC refrigerants/blowing agents and alternative refrigeration technologies. This information is needed for objective and quantitative decisions on policies addressing greenhouse gas emissions from refrigeration and air conditioning equipment. The evaluation assesses the energy use and global warming impacts of refrigeration and air conditioning technologies that could be commercialized during the phase out of HCFCS. Quantitative comparison TEWI for two application areas are presented. Opportunities for significant reductions in TEWI are seen with currently known refrigerants through improved maintenance and servicing practices and improved product designs.

The status and prospects of renewable energy for combating global warming  

Science Journals Connector (OSTI)

Reducing anthropogenic greenhouse gas (GHG) emissions in material quantities, globally, is a critical element in limiting the impacts of global warming. GHG emissions associated with energy extraction and use are a major component of any strategy addressing climate change mitigation. Non-emitting options for electrical power and liquid transportation fuels are increasingly considered key components of an energy system with lower overall environmental impacts. Renewable energy technologies (RETs) as well as biofuels technologies have been accelerating rapidly during the past decades, both in technology performance and cost-competitiveness — and they are increasingly gaining market share. These technology options offer many positive attributes, but also have unique cost/benefit trade-offs, such as land-use competition for bioresources and variability for wind and solar electric generation technologies. This paper presents a brief summary of status, recent progress, some technological highlights for \\{RETs\\} and biofuels, and an analysis of critical issues that must be addressed for \\{RETs\\} to meet a greater share of the global energy requirements and lower GHG emissions.

Errors in applying regression models and wavelet filters used to analyze geophysical signals are discussed: (1) multidecadal natural oscillations (e.g. the quasi 60-year Atlantic Multidecadal Oscillation (AMO), North Atlantic Oscillation (NAO) and Pacific Decadal Oscillation (PDO)) need to be taken into account for properly quantifying anomalous accelerations in tide gauge records such as in New York City; (2) uncertainties and multicollinearity among climate forcing functions prevent a proper evaluation of the solar contribution to the 20th century global surface temperature warming using overloaded linear regression models during the 1900-2000 period alone; (3) when periodic wavelet filters, which require that a record is pre-processed with a reflection methodology, are improperly applied to decompose non-stationary solar and climatic time series, Gibbs boundary artifacts emerge yielding misleading physical interpretations. By correcting these errors and using optimized regression models that reduce multico...

How America can look within to achieve energy security and reduce global warming.  

SciTech Connect (OSTI)

Making major gains in energy efficiency is one of the most economical and effective ways our nation can wean itself off its dependence on foreign oil and reduce its emissions of greenhouse gases. Transportation and buildings, which account for two thirds of American energy usage, consume far more than they need to, but even though there are many affordable energy efficient technologies that can save consumers money, market imperfections inhibit their adoption. To overcome the barriers, the federal government must adopt policies that will transform the investments into economic and societal benefit. And the federal government must invest in research and development programs that target energy efficiency. Energy efficiency is one of America's great hidden energy reserves. We should begin tapping it now. Whether you want the United States to achieve greater energy security by weaning itself off foreign oil, sustain strong economic growth in the face of worldwide competition or reduce global warming by decreasing carbon emissions, energy efficiency is where you need to start. Thirty-five years ago the U.S. adopted national strategies, implemented policies and developed technologies that significantly improved energy efficiency. More than three decades have passed since then, and science and technology have progressed considerably, but U.S. energy policy has not. It is time to revisit the issue. In this report we examine the scientific and technological opportunities and policy actions that can make the United States more energy efficient, increase its security and reduce its impact on global warming. We believe the findings and recommendations will help Congress and the next administration to realize these goals. Our focus is on the transportation and buildings sectors of the economy. The opportunities are huge and the costs are small.

Global warming and ice ages: I. prospects for physics based modulation of global change  

SciTech Connect (OSTI)

It has been suggested that large-scale climate changes, mostly due to atmospheric injection of greenhouse gases connected with fossil-fired energy production, should be forestalled by internationally-agreed reductions in, e.g., electricity generation. The potential economic impacts of such limitations are obviously large: greater than or equal to $10{sup 11}/year. We propose that for far smaller - less than 1% - the mean thermal effects of greenhouse gases may be obviated in any of several distinct ways, some of them novel. These suggestions are all based on scatterers that prevent a small fraction of solar radiation from reaching all or part of the Earth. We propose research directed to quite near-term realization of one or more of these inexpensive approaches to cancel the effects of the greenhouse gas injection. While the magnitude of the climatic impact of greenhouse gases is currently uncertain, the prospect of severe failure of the climate, for instance at the onset of the next Ice Age, is undeniable. The proposals in this paper may lead to quite practical methods to reduce or eliminate all climate failures.

The relative contribution of waste heat from power plants to global warming  

Science Journals Connector (OSTI)

Evidence on global climate change, being caused primarily by rising levels of greenhouse gases in the atmosphere, is perceived as fairly conclusive. It is generally attributed to the enhanced greenhouse effect, resulting from higher levels of trapped heat radiation by increasing atmospheric concentrations of gases such as CO2 (carbon dioxide). Much of these gases originate from power plants and fossil fuel combustion. However, the fate of vast amounts of waste heat rejected into the environment has evaded serious scholarly research. While 1 kWh electricity generation in a typical condensing coal-fired power plant emits around 1 kg of CO2, it also puts about 2 kWh energy into the environment as low grade heat. For nuclear (fission) electricity the waste heat release per kWh is somewhat higher despite much lower CO2 releases. This paper evaluates the impact of waste heat rejection combined with CO2 emissions using Finland and California as case examples. The immediate effects of waste heat release from power production and radiative forcing by CO2 are shown to be similar. However, the long-term (hundred years) global warming by CO2-caused radiative forcing is about twenty-five times stronger than the immediate effects, being responsible for around 92% of the heat-up caused by electricity production.

Global warming estimates, media expectations, and the asymmetry of scientific challenge  

Science Journals Connector (OSTI)

Mass media in the U.S. continue to suggest that scientific consensus estimates of global climate disruption, such as those from the Intergovernmental Panel on Climate Change (IPCC), are “exaggerated” and overly pessimistic. By contrast, work on the Asymmetry of Scientific Challenge (ASC) suggests that such consensus assessments are likely to understate climate disruptions. This paper offers an initial test of the competing expectations, making use of the tendency for science to be self-correcting, over time. Rather than relying in any way on the IPCC process, the paper draws evidence about emerging science from four newspapers that have been found in past work to be biased against reporting IPCC findings, consistently reporting instead that scientific findings are “in dispute.” The analysis considers two time periods — one during the time when the papers were found to be overstating challenges to then-prevailing scientific consensus, and the other focusing on 2008, after the IPCC and former Vice-President Gore shared the Nobel Prize for their work on climate disruption, and before opinion polls showed the U.S. public to be growing more skeptical toward climate science once again. During both periods, new scientific findings were more than twenty times as likely to support the ASC perspective than the usual framing of the issue in the U.S. mass media. The findings indicate that supposed challenges to the scientific consensus on global warming need to be subjected to greater scrutiny, as well as showing that, if reporters wish to discuss “both sides” of the climate issue, the scientifically legitimate “other side” is that, if anything, global climate disruption may prove to be significantly worse than has been suggested in scientific consensus estimates to date.

The ion potential in warm dense matter: wake effects due to streaming degenerate electrons  

E-Print Network [OSTI]

The effective dynamically screened potential of a classical ion in a stationary flowing quantum plasma at finite temperature is investigated. This is a key quantity for thermodynamics and transport of dense plasmas in the warm dense matter regime. To compute this potential a linear response description of the electrons via the Mermin dielectric function is utilized with electron-electron collisions taken into account via a relaxation time approximation. The ion potential strongly deviates from the static Yukawa potential exhibiting the familiar oscillatory structure with attractive minima (wake potential). This potential is analyzed in detail for high-density plasmas with values of the Brueckner parameter in the range $0.1 \\le r_s \\le 1$, for a broad range of plasma temperature and electron streaming velocity. It is shown that wake effects become weaker with increasing temperature of the electrons. Finally, we obtain the minimal electron streaming velocity for which attraction between ions occurs. This veloci...

Long-Term Instrumental and Reconstructed Temperature Records Contradict Anthropogenic Global Warming  

E-Print Network [OSTI]

Monthly instrumental temperature records from 5 stations in the northern hemisphere are analyzed, each of which is local and over 200 years in length, as well as two reconstructed long-range yearly records - from a stalagmite and from tree rings that are about 2000 years long. In the instrumental records, the steepest 100-year temperature fall happened in the 19th century and the steepest rise in the 20th century, both events being of about the same magnitude. Evaluation by the detrended fluctuation analysis (DFA) yields Hurst exponents that are in good agreement with the literature. DFA, Monte Carlo simulations, and synthetic records reveal that both 100-year events were caused by external trends. In contrast to this, the reconstructed records show stronger 100-year rises and falls as quite common during the last 2000 years. These results contradict the hypothesis of an unusual (anthropogenic) global warming during the 20th century. As a hypothesis, the sun's magnetic field, which is correlated with sunspot numbers, is put forward as an explanation. The long-term low-frequency fluctuations in sunspot numbers are not detectable by the DFA in the monthly instrumental records, resulting in the common low Hurst exponents. The same does not hold true for the 2000-year-long reconstructed records, which explains both their higher Hurst exponents and the higher probabilities of strong 100-year temperature fluctuations. A long-term synthetic record that embodies the reconstructed sunspot number fluctuations includes the different Hurst exponents of both the instrumental and the reconstructed records and, therefore, corroborates the conjecture.

Dust Bowl migration as an analog for possible global warming-induced migration from Mexico  

SciTech Connect (OSTI)

As a result of increases in CO{sub 2} and other radiatively important trace gases, scientists have predicted increases in mean worldwide temperatures of 2--5 degrees C over the next 50 to 100 years. Such temperature increases may result in climate modifications that would in turn be associated with increases in drought and desertification and could even change the patterns of the monsoons and tropical rains, which are important to agriculture throughout the world. They predicted that the rise in sea level caused by melting and thermal expansion of glaciers and polar icecaps could flood large population centers, destroying habitation and displacing populations. This will result in approximately 50 million ``environmental refugees`` worldwide, triple the number of today. The expected shifts in precipitation are also likely to result in (1) increased runoff contaminated with pesticides, salts, garbage, sewage, and eroded soil, and (2) drought also leading to increased soil erosion and salinization, as well as depletion of limited water resources. The total impact of global warming on agriculture and human habitation could considerably slow the economic development of some nations and would particularly affect agricultural production. Loss of homes, the inability to raise food, an increased prevalence of disease and worsened economic conditions may drive people to leave their homelands, seeking entry into countries which have more resources and greater resistance to the economic consequences of climatic change. This report looks at the possible environmental impacts and economic impacts of the greenhouse effect on Mexico while using the American Dust Bowl event as an analog.

Long-memory effects in linear-response models of Earth's temperature and implications for future global warming  

E-Print Network [OSTI]

A linearized energy-balance model for global temperature is formulated, featuring a scale-free long-range memory (LRM) response and stochastic forcing representing the influence on the ocean heat reservoir from atmospheric weather systems. The model is parametrized by an effective response strength, the stochastic forcing strength, and the memory exponent. The instrumental global surface temperature record and the deterministic component of the forcing are used to estimate these parameters by means of the maximum-likelihood method. The residual obtained by subtracting the deterministic solution from the observed record is analyzed as a noise process and shown to be consistent with a long-memory time-series model and inconsistent with a short-memory model. By decomposing the forcing record in contributions from solar, volcanic, and anthropogenic activity one can estimate the contribution of each to 20'th century global warming. The LRM model is applied with a reconstruction of the forcing for the last millenni...

Could the Earth's surface Ultraviolet irradiance be blamed for the global warming? A new effect may exist  

E-Print Network [OSTI]

Whether natural factors could interpret the rise of the Earth's surface temperature is still controversial. Though numerous recent researches have reported apparent correlations between solar activity and the Earth's climate, solar activity has encountered a big problem when describing the rapid global warming after 1970s. Our investigation shows the good positive correlations between the Earth's surface Ultraviolet irradiance (280-400 nm) and the Earth's surface temperature both in temporal and spatial variations by analyzing the global surface Ultraviolet irradiance (280-400 nm) and global surface temperature data from 1980-1999. The rise of CO$_2$ cannot interpret the good positive correlations, and we could even get an opposite result to the good correlations when employing the rise of CO$_2$ to describe the relation between them. Based on the good positive correlations, we suggest a new effect, named "Highly Excited Water Vapor" (HEWV) effect, which can interpret how the Sun influences the Earth's surfac...

Projected climate regime shift under future global warming from multi-model, multi-scenario CMIP5 simulations  

Science Journals Connector (OSTI)

Abstract This study examined shifts in climate regimes over the global land area using the Köppen–Trewartha (K–T) climate classification by analyzing observations during 1900–2010, and simulations during 1900–2100 from twenty global climate models participating in Phase 5 of the Coupled Model Inter-comparison Project (CMIP5). Under the Intergovernmental Panel on Climate Change Representative Concentration Pathways 8.5 (RCP8.5) scenario, the models projected a 3°–10 °C warming in annual temperature over the global land area by the end of the twenty-first century, with strong (moderate) warming in the high (middle) latitudes of the Northern Hemisphere and weaker warming in the tropics and the Southern Hemisphere. The projected changes in precipitation vary considerably in space and present greater uncertainties among the models. Overall, the models are consistent in projecting increasing precipitation over the high-latitude of the Northern Hemisphere, and reduced precipitation in the Mediterranean, southwestern North America, northern and southern Africa and Australia. Based on the projected changes in temperature and precipitation, the K–T climate types would shift toward warmer and drier climate types from the current climate distribution. Regions of temperate, tropical and dry climate types are projected to expand, while regions of polar, sub-polar and subtropical climate types are projected to contract. The magnitudes of the projected changes are stronger in the RCP8.5 scenario than the low emission scenario RCP4.5. On average, the climate types in 31.4% and 46.3% of the global land area are projected to change by the end of the twenty-first century under RCP4.5 and RCP8.5 scenarios, respectively. Further analysis suggests that changes in precipitation played a slightly more important role in causing shifts of climate type during the twentieth century. However, the projected changes in temperature play an increasingly important role and dominate shifts in climate type when the warming becomes more pronounced in the twenty-first century.

Evaluation of food waste disposal options by LCC analysis from the perspective of global warming: Jungnang case, South Korea  

SciTech Connect (OSTI)

Highlights: > Various food waste disposal options were evaluated from the perspective of global warming. > Costs of the options were compared by the methodology of life cycle assessment and life cycle cost analysis. > Carbon price and valuable by-products were used for analyzing environmental credits. > The benefit-cost ratio of wet feeding scenario was the highest. - Abstract: The costs associated with eight food waste disposal options, dry feeding, wet feeding, composting, anaerobic digestion, co-digestion with sewage sludge, food waste disposer, incineration, and landfilling, were evaluated in the perspective of global warming and energy and/or resource recovery. An expanded system boundary was employed to compare by-products. Life cycle cost was analyzed through the entire disposal process, which included discharge, separate collection, transportation, treatment, and final disposal stages, all of which were included in the system boundary. Costs and benefits were estimated by an avoided impact. Environmental benefits of each system per 1 tonne of food waste management were estimated using carbon prices resulting from CO{sub 2} reduction by avoided impact, as well as the prices of by-products such as animal feed, compost, and electricity. We found that the cost of landfilling was the lowest, followed by co-digestion. The benefits of wet feeding systems were the highest and landfilling the lowest.

Who remembers a hot summer or a cold winter? The asymmetric effect of beliefs about global warming on perceptions of local climate conditions in the U.S.  

Science Journals Connector (OSTI)

Abstract This paper explores the phenomenon of local climate perception and the extent to which public perceptions match climate conditions as recorded in instrumental climate data. We further examine whether perceptions of changes in local climates are influenced by prior beliefs about global warming, through the process of motivated reasoning. Using national survey data collected in the United States in 2011, we find that subjective experiences of seasonal average temperature and precipitation during the previous winter and summer were related to recorded conditions during each season. Beliefs about global warming also had significant effects on subjective experiences with above-normal temperatures, particularly among those who believed that global warming is not happening. When asked about the summer of 2010, those who believed that global warming is not happening were significantly less likely to report that they had experienced a warmer-than-normal summer, even when controlling for demographics and local climate conditions. These results suggest that the subjective experience of local climate change is dependent not only on external climate conditions, but also on individual beliefs, with perceptions apparently biased by prior beliefs about global warming.

Reply to ‘Quantifying the consensus on anthropogenic global warming in the scientific literature: A re-analysis’  

Science Journals Connector (OSTI)

Abstract Cook et al. (2013) (C13) found that 97% of relevant climate papers endorse anthropogenic global warming (AGW), consistent with previous independent studies. Tol (in press) (T14) agrees that the scientific literature ‘overwhelmingly supports’ AGW, but disputes C13?s methods. We show that T14?s claims of a slightly lower consensus result from a basic calculation error that manufactures approximately 300 nonexistent rejection papers. T14?s claimed impact on consensus due to the reconciliation process is of the wrong sign, with reconciliation resulting in a slight increase (<0.2%) in the consensus percentage. Allegations of data inconsistency are based on statistics unrelated to consensus. Running the same tests using appropriate consensus statistics shows no evidence of inconsistency. We confirm that the consensus is robust at 97±1%.

A procedure for analyzing energy and global warming impacts of foam insulation in U.S. commercial buildings  

SciTech Connect (OSTI)

The objective of this paper is to develop a procedure for evaluating the energy and global warming impacts of alternative insulation technologies for US commercial building applications. The analysis is focused on the sum of the direct contribution of greenhouse gas emissions from a system and the indirect contribution of the carbon dioxide emission resulting from the energy required to operate the system over its expected lifetime. In this paper, parametric analysis was used to calculate building related CO{sub 2} emission in two US locations. A retail mail building has been used as a model building for this analysis. For the analyzed building, minimal R-values of insulation are estimated using ASHRAE 90.1 requirements.

Global Warming Is Driven by Anthropogenic Emissions: A Time Series Analysis Approach  

Science Journals Connector (OSTI)

The solar influence on global climate is nonstationary. Processes such as the Schwabe and Gleissberg cycles of the Sun, or the many intrinsic atmospheric oscillation modes, yield a complex pattern of interaction with multiple time scales. In addition, emissions of greenhouse gases, aerosols, or volcanic dust perturb the dynamics of this coupled system to different and still uncertain extents. Here we show, using two independent driving force reconstruction techniques, that the combined effect of greenhouse gases and aerosol emissions has been the main external driver of global climate during the past decades.

CCS, Nuclear Power and Biomass An Assessment of Option Triangle under Global Warming Mitigation Policy by an Integrated Assessment Model MARIA-23  

Science Journals Connector (OSTI)

Abstract It is well understood that the global climate change caused by the increase of greenhouse gas (GHG) emission would be a serious barrier towards the sustainable development. Nuclear power, CCS and biomass have been regarded as the major options in the GHG mitigation policy. However, since the social acceptance of nuclear power expansion has seriously been changed after the gigantic earthquake on March 11, 2011 followed by the Fukushima Daiichi nuclear power station accident, the energy policy makers are forced to consider both the global warming and the decline of nuclear power simultaneously. This study attempts to address the following key questions: (1) how much additional costs or decline of production will be needed when nuclear power expansion is limited under the GHG emission control policies and (2) to what extent the potential of the biomass and CCS could compensate for the nuclear power reductions. We expand an integrated assessment model, MARIA-23 (Multiregional Approach for Resource and Industry Allocation) to deal with the CCS options and biomass options taking into account the additional carbon emission by cultivation. The simulation results show the interrelationships of the carbon mitigation contributions of the above three major options under various scenarios.

Global properties of K hindrance probed by the ? decay of the warm rotating 174W nucleus  

Science Journals Connector (OSTI)

The K hindrance to the ? decay is studied in the warm rotating 174W nucleus, focusing on the weakening of the selection rules of the K quantum number with increasing excitation energy. 174W was populated by the fusion reaction of 50Ti (at 217 MeV) on a 128Te target, and its ? decay was detected by the AGATA Demonstrator array coupled to a BaF2 multiplicity filter at Laboratori Nazionali di Legnaro of INFN. A fluctuation analysis of ? coincidence matrices gives a similar number of low-K and high-K discrete excited bands. The results are compared to simulations of the ?-decay flow based on a microscopic cranked shell model at finite temperature in which the K mixing is governed by the interplay of Coriolis force with the residual interaction. Agreement between simulations and experiment is obtained only by hindering the E1 decay between low-K and high-K bands by an amount compatible with that determined by spectroscopic studies of K isomers in the same mass region, with a similar trend with excitation energy. The work indicates that K mixing due to temperature effects may play a leading role for the entire body of discrete excited bands, which probes the onset region of K weakening.

Global warming implications of facade parameters: A life cycle assessment of residential buildings in Bahrain  

SciTech Connect (OSTI)

On a global scale, the Gulf Corporation Council Countries (GCCC), including Bahrain, are amongst the top countries in terms of carbon dioxide emissions per capita. Building authority in Bahrain has set a target of 40% reduction of electricity consumption and associated CO{sub 2} emissions to be achieved by using facade parameters. This work evaluates how the life cycle CO{sub 2} emissions of buildings are affected by facade parameters. The main focus is placed on direct and indirect CO{sub 2} emissions from three contributors, namely, chemical reactions during production processes (Pco{sub 2}), embodied energy (Eco{sub 2}) and operational energy (OPco{sub 2}). By means of the life cycle assessment (LCA) methodology, it has been possible to show that the greatest environmental impact occurs during the operational phase (80-90%). However, embodied CO{sub 2} emissions are an important factor that needs to be brought into the systems used for appraisal of projects, and hence into the design decisions made in developing projects. The assessment shows that masonry blocks are responsible for 70-90% of the total CO{sub 2} emissions of facade construction, mainly due to their physical characteristics. The highest Pco{sub 2} emissions factors are those of window elements, particularly aluminium frames. However, their contribution of CO{sub 2} emissions depends largely on the number and size of windows. Each square metre of glazing is able to increase the total CO{sub 2} emissions by almost 30% when compared with the same areas of opaque walls. The use of autoclaved aerated concrete (AAC) walls reduces the total life cycle CO{sub 2} emissions by almost 5.2% when compared with ordinary walls, while the use of thermal insulation with concrete wall reduces CO{sub 2} emissions by 1.2%. The outcome of this work offers to the building industry a reliable indicator of the environmental impact of residential facade parameters. - Highlights: Black-Right-Pointing-Pointer Life cycle carbon assessment of facade parameters. Black-Right-Pointing-Pointer Greatest environmental impact occurs during the operational phase. Black-Right-Pointing-Pointer Masonry blocks are responsible for 70-90% of the total CO2 emissions of facade construction.

Possible change in distribution of seaweed, Sargassum horneri, in northeast Asia under A2 scenario of global warming and consequent effect on some fish  

Science Journals Connector (OSTI)

Abstract Global warming effects on seaweed beds are already perceptible. Their geographical distributions greatly depend on water temperatures. To predict future geographical distributions of brown alga, Sargassum horneri, forming large beds in the northwestern Pacific, we referred to future monthly surface water temperatures at about 1.1° of longitude and 0.6° of latitude in February and August in 2050 and 2100 simulated by 12 organizations under an A2 scenario of global warming. The southern limit of S. horneri distribution is expected to keep moving northward such that it may broadly disappear from Honshu Island, the Chinese coast, and Korean Peninsula in 2100, when tropical Sargassum species such as Sargassum tenuifolium may not completely replace S. horneri. Thus, their forests in 2100 do not substitute those of S. horneri in 2000. Fishes using the beds and seaweed rafts consisting of S. horneri in East China Sea suffer these disappearances.

Final Report and Strategic Plan on the Feasibility Study to Assess Geothermal Potential on Warm Springs Reservation Lands. Report No. DOE/GO/15177  

SciTech Connect (OSTI)

In 2005 the Confederated Tribes of Warm Springs Tribal Council authorized an evaluation of the geothermal development potential on the Confederated Tribes of Warm Springs Reservation of Oregon. Warm Springs Power & Water Enterprises obtained a grant from the U.S. Department of Energy to conduct a geological assessment and development estimate. Warm Springs Power & Water Enterprises utilized a team of expert consultants to conduct the study and develop a strategic plan. The resource assessment work was completed in 2006 by GeothermEx Inc., a consulting company specializing in geothermal resource assessments worldwide. The GeothermEx report indicates there is a 90% probability that a commercial geothermal resource exists on tribal lands in the Mt. Jefferson area. The geothermal resource assessment and other cost, risk and constraints information has been incorporated into the strategic plan.

On the impact of urban heat island and global warming on the power demand and electricity consumption of buildings—A review  

Science Journals Connector (OSTI)

Abstract Urban heat island and global warming increase significantly the ambient temperature. Higher temperatures have a serious impact on the electricity consumption of the building sector increasing considerably the peak and the total electricity demand. The present paper aims to collect, analyze and present in a comparative way existing studies investigating the impact of ambient temperature increase on electricity consumption. Analysis of eleven studies dealing with the impact of the ambient temperature on the peak electricity demand showed that for each degree of temperature increase, the increase of the peak electricity load varies between 0.45% and 4.6%. This corresponds to an additional electricity penalty of about 21 (±10.4) W per degree of temperature increase and per person. In parallel, analysis of fifteen studies examining the impact of ambient temperature on the total electricity consumption, showed that the actual increase of the electricity demand per degree of temperature increase varies between 0.5% and 8.5%.

Global Optical Potential for the Elastic Scattering of $^{6}$He at Low Energies  

E-Print Network [OSTI]

A set of global optical potential has been derived to describe the interactions of $^{6}$He at low energies. The elastic scattering angular distribution data measured so far for many systems, ranging from $^{12}$C to $^{209}$Bi, have been considered within the framework of the optical model in order to find a global potential set to describe the experimental data consistently. We report that very good agreement between theoretical and experimental results has been obtained with small $\\chi^{2}/N$ values by using the derived potential set. The reaction cross section and volume integrals of the potentials have been deduced from the theoretical calculations for all studied systems at relevant energies.

Derivation of an optical potential for statically deformed rare-earth nuclei from a global spherical potential  

E-Print Network [OSTI]

The coupled-channel theory is a natural way of treating nonelastic channels, in particular those arising from collective excitations characterized by nuclear deformations. A proper treatment of such excitations is often essential to the accurate description of experimental nuclear-reaction data and to the prediction of a wide variety of scattering observables. Stimulated by recent work substantiating the near validity of the adiabatic approximation in coupled-channel calculations for scattering on statically deformed nuclei, we explore the possibility of generalizing a global spherical optical model potential (OMP) to make it usable in coupled-channel calculations on this class of nuclei. To do this, we have deformed the Koning-Delaroche global spherical potential for neutrons, coupling a sufficient number of states of the ground state band to ensure convergence. We present an extensive study of the effects of collective couplings and nuclear deformations on integrated cross sections as well as on angular distributions for neutron-induced reactions on statically deformed nuclei in the rare-earth region. We choose isotopes of three rare-earth elements (Gd, Ho, W), which are known to be nearly perfect rotors, to exemplify the results of the proposed method. Predictions from our model for total, elastic and inelastic cross sections, as well as for elastic and inelastic angular distributions, are in reasonable agreement with measured experimental data. These results suggest that the deformed Koning-Delaroche potential provides a useful regional neutron optical potential for the statically deformed rare earth nuclei.

Warm inflation in presence of magnetic fields  

SciTech Connect (OSTI)

We present preliminary results on the possible effects that primordial magnetic fields can have for a warm inflation scenario, based on global supersymmetry, with a new-inflation-type potential. This work is motivated by two considerations: first, magnetic fields seem to be present in the universe on all scales which rises de possibility that they could also permeate the early universe; second, the recent emergence of inflationary models where the inflaton is not assumed to be isolated but instead it is taken as an interacting field, even during the inflationary expansion. The effects of magnetic fields are included resorting to Schwinger's proper time method.

Global Potential for Biomethane Production with Carbon Capture, Transport and Storage up to 2050  

Science Journals Connector (OSTI)

Abstract Biomass in combination with carbon capture and storage (CCS) is one of few options that make a reduction of global CO2 concentration in the atmosphere possible. This option is likely to be required to meet climate targets. This study shows the global potential for combining bio-energy conversion with CCS (BE-CCS) up to 2050. The assessment focuses on two BE-CCS routes for the production of biomethane, based on gasification and anaerobic digestion. Routes for the production of power and liquid fuels have been addressed in an earlier study by IEAGHG. For the two routes the technical and economic potential was analysed. The results show that deployment of the global technical potential can result in negative greenhouse gas emissions (GHG) up to 3.5 Gt CO2-eq. on an annual basis in 2050. Including avoided emissions by replacing natural gas, the annual greenhouse gas emission savings could add up to almost 8 Gt of CO2-eq in 2050. The economic potential reaches up to 0.8 Gt of negative GHG emissions when assuming a CO2 price of 50 €/tonne.

We present results from a homogeneous analysis of the broadband 0.3-10 keV CCD resolution as well as of soft X-ray high-resolution grating spectra of a hard X-ray flux-limited sample of 26 Seyfert galaxies observed with XMM-Newton. Our goal is to characterise the warm absorber (WA) properties along the line-of-sight to the active nucleus. We significantly detect WAs in $65\\%$ of the sample sources. Our results are consistent with WAs being present in at least half of the Seyfert galaxies in the nearby Universe, in agreement with previous estimates . We find a gap in the distribution of the ionisation parameter in the range $0.5warm absorber flow is probably constituted by a clumpy distribution of discrete clouds rather than a continuous medium.

Progress in the Development of Global Medium-Energy Nucleon-Nucleus Optical Model Potentials  

E-Print Network [OSTI]

Two existing global medium-energy nucleon-nucleus phenomenological optical model potentials are described and compared with experiment and with each other. The first of these employs a Dirac approach (second-order reduction) that is global in projectile energy and projectile isospin and applies to the target nucleus 208-Pb. Here the standard S-V (isoscalar-scalar, isoscalar-vector) model has been extended to include the corresponding isovector components by introduction of a relativistic Lane model. The second of these employs a relativistic equivalent to the Schroedinger equation and is global in projectile energy, projectile isospin, and target (Z,A). Here, particular attention is given to predictions for the integrated scattering observables - neutron total cross sections and proton total reaction cross sections - and their sensitivity to the absorptive parts of the potential. Finally, current work is described and the influence of the nuclear bound state problem (treated in relativistic mean field theory) on the Dirac scattering problem is mentioned.

Chapter 8 - Rift Valley Fever Virus: A Virus with Potential for Global Emergence  

Science Journals Connector (OSTI)

Abstract Rift Valley fever virus (RVFV) is an important emerging zoonotic threat to veterinary and public health with potential to cause a severe socioeconomic impact on people’s livelihoods. The capacity of the virus to spread into new territories by crossing significant natural geographic barriers and re-emerge in endemic regions after long periods of silence, to cause large outbreaks in human and animal populations, constitutes a formidable challenge for public and veterinary health authorities as well as for scientific communities worldwide. In spite of recent advances in research on RVFV pathogenesis, molecular epidemiology, outbreak prediction, and development of new diagnostic tools and vaccines, some fundamental aspects of the epidemiology and ecology of the virus remain elusive. Large outbreaks of RVF are associated with anomalous high rainfalls leading to massive flooding and the resultant swarms of competent mosquito vectors transmitting the virus to a wide range of susceptible vertebrate species. However, the exact mechanism of RVFV natural transmission during interepizootic periods remains largely unknown, including the postulated long-term virus persistence in transovarially infected eggs of floodwater Aedes mosquito species, and the role of wild mammals as reservoirs. The presence of competent mosquito vectors in countries free of RVF, the wide range of mammals susceptible to the virus, the global changes in climate, and increased animal trade and travel are some of the factors that might contribute to international spread. This chapter provides the background to the major outbreaks, molecular biology and epidemiology of RVFV, and overviews aspects of ecology, host and vector range which make the virus a potential global emerging threat.

Global change and local solutions: Tapping the unrealized potential of citizen science for biodiversity research  

Science Journals Connector (OSTI)

Abstract The collective impact of humans on biodiversity rivals mass extinction events defining Earth’s history, but does our large population also present opportunities to document and contend with this crisis? We provide the first quantitative review of biodiversity-related citizen science to determine whether data collected by these projects can be, and are currently being, effectively used in biodiversity research. We find strong evidence of the potential of citizen science: within projects we sampled (n = 388), ?1.3 million volunteers participate, contributing up to $2.5 billion in-kind annually. These projects exceed most federally-funded studies in spatial and temporal extent, and collectively they sample a breadth of taxonomic diversity. However, only 12% of the 388 projects surveyed obviously provide data to peer-reviewed scientific articles, despite the fact that a third of these projects have verifiable, standardized data that are accessible online. Factors influencing publication included project spatial scale and longevity and having publically available data, as well as one measure of scientific rigor (taxonomic identification training). Because of the low rate at which citizen science data reach publication, the large and growing citizen science movement is likely only realizing a small portion of its potential impact on the scientific research community. Strengthening connections between professional and non-professional participants in the scientific process will enable this large data resource to be better harnessed to understand and address global change impacts on biodiversity.

A model for the contribution of macrophyte-derived organic carbon in harvested tidal freshwater marshes to surrounding estuarine and oceanic ecosystems and its response to global warming  

Science Journals Connector (OSTI)

Abstract The tidal freshwater marshes dominated by Phragmites australis (common reed) in the Chongxi Wetland are important components of the Yangtze River estuary in China. The litter from P. australis is exported to the surrounding estuarine area and the sea with the tidal flushing in the form of plant residue, particulate organic matter, and dissolved organic matter and is an important organic carbon resource of the East China Sea. A model was constructed using STELLA® software (version 9.1.3) to simulate the contribution of macrophyte-derived organic carbon to surrounding estuary and ocean ecosystems. The model is based on the monitoring and observational data from field surveys and published information on the Chongxi Wetland from 2008 to 2011, and the response of the total organic carbon flowing out of the wetland to global changes was also predicted in conditions of plant shoots that were annually harvested in winter. The results demonstrate the following: (1) the annual contributed organic carbon is 891 g C m?2, of which 612 g C m?2 flows out of the wetland directly as plant residue; (2) total organic carbon continually increases after a short decrease at the start of April of 2010, retains a high value from mid-July to mid-November and rapidly decreases to approximately zero during the harvest of the aboveground plant organs; and (3) accumulated annual organic carbon contributions to the surrounding estuarine and oceanic ecosystems are predicted to increase as the global average temperature rises, and the sea level increases.

Abstract The effects of a transatlantic trade agreement on the global forest sector were assessed with the Global Forest Products Model, conditional on previous macroeconomic impacts predicted with a general equilibrium model. Comprehensive tariff elimination per se had little effect on the forest sector. However, with deeper reforms and integration consumption would increase twice as much in percent in the US as in the EU. Net trade decreased in the US more than in the EU while it increased in Asia. Consumers and producers’ welfare increased by $7000 million in the EU and $14,000 million in the US, but decreased in some third countries, especially in Asia.

impacts of warming temperatures on California's electricity impacts of warming temperatures on California's electricity system Title Estimating impacts of warming temperatures on California's electricity system Publication Type Journal Article Year of Publication 2013 Authors Sathaye, Jayant A., Larry L. Dale, Peter H. Larsen, Gary A. Fitts, Kevin Koy, Sarah M. Lewis, and André Frossard Pereira de Lucena Journal Global Environmental Change Volume 23 Start Page 499 Issue 2 Pagination 499-511 Date Published 04/2013 Keywords EES-EG, electricity markets and policy group Abstract Despite a clear need, little research has been carried out at the regional-level to quantify potential climate-related impacts to electricity production and delivery systems. This paper introduces a bottom-up study of climate change impacts on California's energy infrastructure, including high temperature effects on power plant capacity, transmission lines, substation capacity, and peak electricity demand. End-of-century impacts were projected using the A2 and B1 Intergovernmental Panel on Climate Change emission scenarios. The study quantifies the effect of high ambient temperatures on electricity generation, the capacity of substations and transmission lines, and the demand for peak power for a set of climate scenarios. Based on these scenarios, atmospheric warming and associated peak demand increases would necessitate up to 38% of additional peak generation capacity and up to 31% additional transmission capacity, assuming current infrastructure. These findings, although based on a limited number of scenarios, suggest that additional funding could be put to good use by supporting R&D into next generation cooling equipment technologies, diversifying the power generation mix without compromising the system's operational flexibility, and designing effective demand side management programs.

The global energy challenges of the 21st century and the potential Russian contribution to world and regional nuclear power  

Science Journals Connector (OSTI)

The paper considers the world energy demand until the middle of the 21st century, as well as the possible solutions for this challenge. On the basis of the mathematical model developed at the Kurchatov Institute in 2003-2005, the vision of the global nuclear energy system and its potential contribution to the energy mix was analysed. The energy mix picture by mid-century would contain an 'unsatisfied demand' area (i.e., resources that should be used to meet the projected energy demand). Thus, the global energy challenges of the 21st century energy supply do not impose any upper limit on nuclear energy development, the scale of which would be determined by development opportunities. The key nuclear energy requirements, including the fuel supply, the need for innovative technologies and the extension of application spheres, are determined by the scale of its use. Being one of the founders of the First Nuclear Era, Russia has a unique experience in solving the key nuclear energy problems of the 20th century and is capable of making a worthy contribution to the challenges faced in the 21st century.

Code calculations are given of potential and the total force exerted on the sphere by the flowing plasma. This force is of crucial importance to the problem of dusty plasmas, and the present results are the first for a collisionless plasma to take account of the full self-consistent potential. They reveal discrepancies amounting to as large as 20% with the standard analytic expressions, in parameter regimes where the analytic approximations might have been expected

The potential of different artificial neural network (ANN) techniques in daily global solar radiation modeling based on meteorological data  

SciTech Connect (OSTI)

The main objective of present study is to predict daily global solar radiation (GSR) on a horizontal surface, based on meteorological variables, using different artificial neural network (ANN) techniques. Daily mean air temperature, relative humidity, sunshine hours, evaporation, and wind speed values between 2002 and 2006 for Dezful city in Iran (32 16'N, 48 25'E), are used in this study. In order to consider the effect of each meteorological variable on daily GSR prediction, six following combinations of input variables are considered: (I)Day of the year, daily mean air temperature and relative humidity as inputs and daily GSR as output. (II)Day of the year, daily mean air temperature and sunshine hours as inputs and daily GSR as output. (III)Day of the year, daily mean air temperature, relative humidity and sunshine hours as inputs and daily GSR as output. (IV)Day of the year, daily mean air temperature, relative humidity, sunshine hours and evaporation as inputs and daily GSR as output. (V)Day of the year, daily mean air temperature, relative humidity, sunshine hours and wind speed as inputs and daily GSR as output. (VI)Day of the year, daily mean air temperature, relative humidity, sunshine hours, evaporation and wind speed as inputs and daily GSR as output. Multi-layer perceptron (MLP) and radial basis function (RBF) neural networks are applied for daily GSR modeling based on six proposed combinations. The measured data between 2002 and 2005 are used to train the neural networks while the data for 214 days from 2006 are used as testing data. The comparison of obtained results from ANNs and different conventional GSR prediction (CGSRP) models shows very good improvements (i.e. the predicted values of best ANN model (MLP-V) has a mean absolute percentage error (MAPE) about 5.21% versus 10.02% for best CGSRP model (CGSRP 5)).

Warming impact on energy use of HVAC system in buildings of different thermal qualities and in different climates  

Science Journals Connector (OSTI)

Abstract In order to combat climate change, energy use in the building must be further reduced. Heating ventilation and air conditioning (HVAC) systems in residential buildings account for considerable fraction of global energy consumption. The potential contribution the domestic sector can make in reducing energy consumption is recognized worldwide. The driving energy of \\{HVACs\\} depends on the thermal quality of the building envelope (TQBE) and outside temperature. Definitely, building regulations are changing with the time toward reduce the thermal loads of buildings. However, most of the existing residential buildings were built to lower TQBE. For instant, 72% of residential dwellings in the 15-EU were built before 1972. To investigate the impact of warming on driving energy of \\{HVACs\\} of a residential building a computer model was developed. Three climate categories/cities were considered, i.e. Stockholm (cold), Istanbul (mild), and Doha (hot). In each city, two buildings were modeled: one was assumed to be built according to the current local buildings regulations (standard TQBE), while the anther was built to lower TQBE. The simulations were run for present and future (in 2050) outdoor designing conditions. The calculations show that the impact of the warming on annual driving energy of \\{HVACs\\} (reduction or increase) depends very much on the climate category and on the TQBE. Based on the climate and TQBE, the change in annual \\{HVACs\\} energy varies from ?7.4% (in cold climate) to 12.7% (in hot climate). In mild climate, it was shown that the warming does not have significant impact on annual \\{HVACs\\} energy. Improving the TQBE can mitigate the impact of the warming.

Global warming accelerates drought-induced forest death  

ScienceCinema (OSTI)

Many southwestern forests in the United States will disappear or be heavily altered by 2050, according to a series of joint Los Alamos National Laboratory-University of New Mexico studies. Nathan McDowell, a Los Alamos plant physiologist, and William Pockman, a UNM biology professor, explain that their research, and more from scientists around the world, is forecasting that by 2100 most conifer forests should be heavily disturbed, if not gone, as air temperatures rise in combination with drought. "Everybody knows trees die when there's a drought, if there's bark beetles or fire, yet nobody in the world can predict it with much accuracy." McDowell said. "What's really changed is that the temperature is going up," thus the researchers are imposing artificial drought conditions on segments of wild forest in the Southwest and pushing forests to their limit to discover the exact processes of mortality and survival. The study is centered on drought experiments in woodlands at both Los Alamos and the Sevilleta National Wildlife Refuge in central New Mexico. Both sites are testing hypotheses about how forests die on mature, wild trees, rather than seedlings in a greenhouse, through the ecosystem-scale removal of 50 percent of yearly precipitation through large water-diversion trough systems.

SUBTASK 7.2 GLOBAL WARMING AND GREEHOUSE GASES  

SciTech Connect (OSTI)

Evaluation of current climatic trends and reconstruction of paleoclimatic conditions for Devils Lake have been conducted based on diatom-inferred salinity for the last 2000 years. The 3-year cross-disciplinary research, funded by the U.S. Department of Energy (DOE) was carried out by the Energy & Environmental Research Center (EERC) and St. Croix Watershed Research Station (SCWRS) at the Science Museum of Minnesota. The results indicate that frequent climatic fluctuations resulting in alternating periods of drought and wet conditions are typical for the northern Great Plains and suggest that the severity and length of extremes exceeded those on modern record. Devils Lake has experienced five fresh periods and two minor freshening periods in the last 2000 years. Transitions between fresh and saline periods have been relatively fast, representing lake level changes that have been similar to those observed in the last 150 years. From 0 to 1070 A.D., Devils Lake showed more variable behavior, with fresh phases centered at 200, 500, 700, and 1000 A.D. From 1070 A.D. to present, Devils Lake was generally saline, experiencing two minor freshening periods at 1305-1315 and 1800-1820 A.D and the major current freshening from 1960 A.D. to present.

On modification of global warming by sulfate aerosols  

SciTech Connect (OSTI)

There is increasing evidence that the response of climate to increasing greenhouse gases may be modified by accompanying increases in sulfate aerosols. In this study, the patterns of response in the surface climatology of a coupled ocean-atmosphere general circulation model forced by increases in carbon dioxide alone is compared with those obtained by increasing carbon dioxide and aerosol forcing. The simulations are run from early industrial times using the estimated historical forcing and continued to the end of the twenty-first century assuming a nonintervention emissions scenario for greenhouse gases and aerosols. The comparison is made for the period 2030-2050 when the aerosol forcing is a maximum. In winter, the cooling due to aerosols merely tends to reduce the response to carbon dioxide, whereas in summer, it weakens the monsoon circulations and reverses some of the changes in the hydrological cycle on increasing carbon dioxide. This response is in some respects similar to that found in simulations with changed orbital parameters, as between today and the middle Holocene. The hydrological response in the palaeosimulations is supported by palaeoclimatic reconstructions. The results of changes in aerosol concentrations of the magnetic projected in the scenarios would have a major effect on regional climate, especially over Europe and Southeast Asia. 74 refs., 12 figs., 6 tabs.

Variance in trace constituents following the final stratospheric warming  

SciTech Connect (OSTI)

Temporal variances in the concentration of trace species are examined within the northern hemisphere stratosphere following the final warming. Variances are computed utilizing an annual cycle run of a tracer transport model and stratospheric balloon observations. The model uses winds generated with a general circulation model to transport N{sub 2}O. Regions of significant N{sub 2}O variance are produced immediately following the modeled final warming as zonally inhomogeneous N{sub 2}O anomalies are created during the warming, then advected passively about the pole by easterly winds. Diffusion rapidly dissipates these anomalies and decreases the associated stratospheric tracer variance to very low levels by June. On monthly timescales the 10 day normal mode explains up to 50% of the modeled variance of N{sub 2}O during summer. On these timescales potential temperature exhibits less variability than N{sub 2}O, as horizontal parcel displacements are relatively ineffective at inducing potential temperature variability. An examination of balloon observations of N{sub 2}O and other long lived trace species, between 40{degree} and 50{degree}N, indicates that the primary component of the tracer variance during June is on an interannual time scale. The authors attribute this interannual variability to stratospheric variability during the winter and early spring months imprinted onto the distributions of long lived tracers. Potential temperatures does not exhibit much interannual variability because it does not retain a memory of the previous winters circulation.

Review of comparative LCAs of food waste management systems - Current status and potential improvements  

SciTech Connect (OSTI)

Highlights: Black-Right-Pointing-Pointer GHG-emissions from different treatment alternatives vary largely in 25 reviewed comparative LCAs of bio-waste management. Black-Right-Pointing-Pointer System-boundary settings often vary largely in reviewed studies. Black-Right-Pointing-Pointer Existing LCA guidelines give varying recommendations in relation to several key issues. - Abstract: Twenty-five comparative cycle assessments (LCAs) addressing food waste treatment were reviewed, including the treatment alternatives landfill, thermal treatment, compost (small and large scale) and anaerobic digestion. The global warming potential related to these treatment alternatives varies largely amongst the studies. Large differences in relation to setting of system boundaries, methodological choices and variations in used input data were seen between the studies. Also, a number of internal contradictions were identified, many times resulting in biased comparisons between alternatives. Thus, noticed differences in global warming potential are not found to be a result of actual differences in the environmental impacts from studied systems, but rather to differences in the performance of the study. A number of key issues with high impact on the overall global warming potential from different treatment alternatives for food waste were identified through the use of one-way sensitivity analyses in relation to a previously performed LCA of food waste management. Assumptions related to characteristics in treated waste, losses and emissions of carbon, nutrients and other compounds during the collection, storage and pretreatment, potential energy recovery through combustion, emissions from composting, emissions from storage and land use of bio-fertilizers and chemical fertilizers and eco-profiles of substituted goods were all identified as highly relevant for the outcomes of this type of comparisons. As the use of LCA in this area is likely to increase in coming years, it is highly relevant to establish more detailed guidelines within this field in order to increase both the general quality in assessments as well as the potentials for cross-study comparisons.

Surface electromagnetic wave equations in a warm magnetized quantum plasma  

SciTech Connect (OSTI)

Based on the single-fluid plasma model, a theoretical investigation of surface electromagnetic waves in a warm quantum magnetized inhomogeneous plasma is presented. The surface electromagnetic waves are assumed to propagate on the plane between a vacuum and a warm quantum magnetized plasma. The quantum magnetohydrodynamic model includes quantum diffraction effect (Bohm potential), and quantum statistical pressure is used to derive the new dispersion relation of surface electromagnetic waves. And the general dispersion relation is analyzed in some special cases of interest. It is shown that surface plasma oscillations can be propagated due to quantum effects, and the propagation velocity is enhanced. Furthermore, the external magnetic field has a significant effect on surface wave's dispersion equation. Our work should be of a useful tool for investigating the physical characteristic of surface waves and physical properties of the bounded quantum plasmas.

Constraining warm dark matter with cosmic shear power spectra  

SciTech Connect (OSTI)

We investigate potential constraints from cosmic shear on the dark matter particle mass, assuming all dark matter is made up of light thermal relic particles. Given the theoretical uncertainties involved in making cosmological predictions in such warm dark matter scenarios we use analytical fits to linear warm dark matter power spectra and compare (i) the halo model using a mass function evaluated from these linear power spectra and (ii) an analytical fit to the non-linear evolution of the linear power spectra. We optimistically ignore the competing effect of baryons for this work. We find approach (ii) to be conservative compared to approach (i). We evaluate cosmological constraints using these methods, marginalising over four other cosmological parameters. Using the more conservative method we find that a Euclid-like weak lensing survey together with constraints from the Planck cosmic microwave background mission primary anisotropies could achieve a lower limit on the particle mass of 2.5 keV.

A warm and wet Little Climatic Optimum and a cold and dry Little Ice Age in the southern Rocky Mountains, USA  

SciTech Connect (OSTI)

In the next century, increases in atmospheric trace gas concentration could warm the global average temperature beyond what it has ranged during the past century. Examination of larger-than-historic climatic changes that have occurred in the past in specific regions provides realistic context for evaluating such potential future changes. This paper has contrasted the climatic manifestation of the Little Climatic Optimum or Medieval Warm Period (AD 900--1300) with that of the Little Ice Age (AD 1300--1850) in the northern Colorado Plateau region of the southwestern USA. The zenith of the Anasazi occupation coincides with the former and their demise coincides with the latter, when conditions became too cold and especially dry (in the summer) to support upland dry farming. During the height of the Little Climatic Optimum the region was characterized by a relatively long growing season and greater winter and summer precipitation than that of today. This resulted in a relatively rapid development of a potential dry-farming belt that was twice as wide as the present and areas that cannot be dry farmed today were routinely farmed by the Anasazi. Such conditions would be beneficial to dry farmers in the Four Corners region if those conditions were repeated in the near future.

I know that reptile blood is a bit different than mammal blood, but is that the difference or is it a difference in the other cells of the body? Replies: Warm blooded refers to an animals ability to maintain its body temperature at a constant level. Cold blooded animal's bodies stay at the temperature of environment around them (more or less). The mechanism by which a warm blooded animal does this is by generating heat, mostly through muscle movement (but by other biochemical processes too). An example of this is shivering. Warm blooded animals also cool themselves off by sweating, panting (and other ways). In mammals the hypothalamic area of the brain has much to do with controlling these reflex processes

Simulation of warm dense matter requires computational methods that capture both quantum and classical behavior efficiently under high-temperature, high-density conditions. Currently, density functional theory molecular dynamics is used to model electrons and ions, but this method's computational cost skyrockets as temperatures and densities increase. We propose finite-temperature potential functional theory as an in-principle-exact alternative that suffers no such drawback. We derive an orbital-free free energy approximation through a coupling-constant formalism. Our density approximation and its associated free energy approximation demonstrate the method's accuracy and efficiency.

Ultrafast Spectroscopy of Warm Dense Matter Print Ultrafast Spectroscopy of Warm Dense Matter Print Being neither solid, liquid, gas, nor plasma, warm dense matter (WDM) occupies a no man's land in the map of material phases. Its temperature can range between that of planetary cores (tens of thousands K) to that of stellar cores (hundreds of thousands K). Not only is it prevalent throughout the universe, it is relevant to inertial confinement fusion (ICF) and material performance under extreme conditions. However, because of its extreme temperatures and pressures, WDM tends to be drastically transient and thus difficult to study in the laboratory. Now, researchers have set up ultrafast x-ray absorption spectroscopy at the ALS to measure the electronic structure of WDMs, demonstrating that fast-changing electron temperatures of matter under extreme conditions can be determined with picosecond resolution.

Electrical conductivity of warm dense tungsten  

Science Journals Connector (OSTI)

Abstract The electrical conductivity of warm dense tungsten plasma has been investigated successfully by a linear mixture rule considering various interactions of electrons with electrons, atoms, and ions. The plasma composition is calculated by the nonideal Saha equation. The interesting regime for tungsten plasma spans from weakly coupled and nondegenerate regime to strongly coupled and partial degenerate state. The electrical conductivity calculated is in reasonable agreement with the exploding wire experiments and other theoretical models. The present result demonstrates that the theoretical model is valid for the electrical conductivity of tungsten plasma in the warm dense matter regime.

Long-term soil warming and Carbon Cycle Feedbacks to the Climate System  

SciTech Connect (OSTI)

The primary objective of the proposed research was to quantify and explain the effects of a sustained in situ 5oC soil temperature increase on net carbon (C) storage in a northeastern deciduous forest ecosystem. The research was done at an established soil warming experiment at the Harvard Forest in central Massachusetts – Barre Woods site established in 2001. In the field, a series of plant and soil measurements were made to quantify changes in C storage in the ecosystem and to provide insights into the possible relationships between C-storage changes and nitrogen (N) cycling changes in the warmed plots. Field measurements included: 1) annual woody increment; 2) litterfall; 3) carbon dioxide (CO2) efflux from the soil surface; 4) root biomass and respiration; 5) microbial biomass; and 6) net N mineralization and net nitrification rates. This research was designed to increase our understanding of how global warming will affect the capacity of temperate forest ecosystems to store C. The work explored how soil warming changes the interactions between the C and N cycles, and how these changes affect land-atmosphere feedbacks. This core research question framed the project – What are the effects of a sustained in situ 5oC soil temperature increase on net carbon (C) storage in a northeastern deciduous forest ecosystem? A second critical question was addressed in this research – What are the effects of a sustained in situ 5{degrees}C soil temperature increase on nitrogen (N) cycling in a northeastern deciduous forest ecosystem?

We consider the model of relativistic weakly interacting massive particles and try to impose an upper bound on their actual and past warmness through the analysis of density perturbations and comparison with the LSS data. It is assumed that the DM can be described by the recently invented model of reduced relativistic gas (RRG). The equation of state of the RRG model is closely reproducing the one of the Maxwell distribution, while being much simpler. This advantage of the RRG model makes our analysis very efficient. As a result we arrive at the rigid and model-independent bound for the DM warmness without using the standard (much more sophisticated) approach based on the Einstein-Boltzmann system of equations.

Storing images in warm atomic vapor  

E-Print Network [OSTI]

Reversible and coherent storage of light in atomic medium is a key-stone of future quantum information applications. In this work, arbitrary two-dimensional images are slowed and stored in warm atomic vapor for up to 30 $\\mu$s, utilizing electromagnetically induced transparency. Both the intensity and the phase patterns of the optical field are maintained. The main limitation on the storage resolution and duration is found to be the diffusion of atoms. A techniqueanalogous to phase-shift lithography is employed to diminish the effect of diffusion on the visibility of the reconstructed image.

Global Environmental Benefits Global Environmental Benefits Gasification Systems Global Environmental Benefits Environmental performance for future energy production systems is a much greater factor as emission standards tighten in the United States and worldwide. The outstanding environmental performance of gasification systems makes it an excellent technology for the clean production of electricity and other products. In addition, the reduction of CO2 emissions is one of the major challenges facing industry in response to global climate change. Other countries with coal reserves might potentially import technologies developed in the United States to enable low-cost gasification with carbon capture and EOR or sequestration. Not only will this benefit the U.S. gasification technology industry, but it will also result in a global environmental benefit through more affordable control of greenhouse gases (GHGs). See the U.S. Environmental Protection Agency (EPA) link below for a summary of the impact of fossil fuels without carbon capture on CO2 emissions, on the GHG contributions of different countries, and of the projected impact of developing countries to 2030:

Constructing warm inflationary model in brane-antibrane system  

E-Print Network [OSTI]

Recently, various observational data predict a possibility that inflation may naturally occur in a warm region. In this scenario, radiation is produced during the inflation epoch and reheating is avoided. The main question arises that what is the origin of warm inflation in 4D universe? We answer to this question in brane-antibrane system. We propose a model that allows all cosmological parameters like the scale factor a, the Hubble parameter H and phantom energy density depend on the equation of state parameter in transverse dimension between two branes. Thus, an enhancement in these parameters can be a signature of some evolutions in extra dimension. In our model, the expansion of 4D universe is controlled by the separation distance between branes and evolves from non-phantom phase to phantom one. Consequently, phantom-dominated era of the universe accelerates and ends up in big-rip singularity. Also, we show that as the tachyon potential increases, the effect of interaction between branes on the 4D universe expansion becomes systematically more effective, because at higher energies there exists more channels for flowing energy from extra dimension to other four dimensions. Finally, we test our model against WMAP and Planck data and obtain the ripping time. According to experimental data, $N\\simeq 50$ case leads to $n_{s}\\simeq 0.96$, where \\emph{N} and $n_{s}$ are the number e-folds and the spectral index respectively. This standard case may be found in $0.01 occurs is $t_{rip}=33(Gyr)$.

100 LPW 800 Lm Warm White LED  

SciTech Connect (OSTI)

An illumination grade warm white (WW) LED, having correlated color temperature (CCT) between 2800 K and 3500K and capable of producing 800 lm output at 100 lm/W, has been developed in this program. The high power WW LED is an ideal source for use as replacement for incandescent, and Halogen reflector and general purpose lamps of similar lumen value. Over the two year period, we have made following accomplishments: developed a high power warm white LED product and made over 50% improvements in light output and efficacy. The new high power WW LED product is a die on ceramic surface mountable LED package. It has four 1x1 mm{sup 2} InGaN pump dice flip chip attached to a ceramic submount in 2x2 array, covered by warm white phosphor ceramic platelets called Lumiramicâ?¢ and an overmolded silicone lens encapsulating the LED array. The performance goal was achieved through breakthroughs in following key areas: (1) High efficiency pump LED development through pump LED active region design and epi growth quality improvement (funded by internal programs). (2) Increase in injection efficiency (IE) represented by reduction in forward voltage (V{sub f}) through the improvement of the silver-based p-contact and a reduction in spreading resistance. The injection efficiency was increased from 80% at the start of the program to 96% at the end of the program at 700 mA/mm{sup 2}. (3) Improvement in thermal design as represented by reduction in thermal resistance from junction to case, through improvement of the die to submount connection in the thin film flip chip (TFFC) LED and choosing the submount material of high thermal conductivity. A thermal resistance of 1.72 K/W was demonstrated for the high power LED package. (4) Improvement in extraction efficiency from the LED package through improvement of InGaN die level and package level optical extraction efficiency improvement. (5) Improvement in phosphor system efficiency by improving the lumen equivalent (LE) and phosphor package efficiency (PPE) through improvement in phosphor-package interactions. Another achievement in the development of the phosphor integration technology is the demonstration of tight color control. The high power WW LED product developed has been proven to have good reliability. The manufacturing of the product will be done in Philips Lumiledsâ?? LUXEON Rebel production line which has produced billions of high power LEDs. The first high power WW LED product will be released to the market in 2011.

Integrated global background monitoring network  

SciTech Connect (OSTI)

This paper describes the background and elucidates the need for an integrated global background monitoring network. This network should: establish reference levels for pollutants that have potential for global contaminatin, serve as an early warning site for detecting global spread of pollutants, and establish baseline levels for selected ecosystem parameters against which data from more impacted areas can be compared. This paper proposes the following: (1) establish an integrated global background monitoring network for pollutants and ecosystem parameters; (2) pollutant measurements be multi-media; (3) carry out ecosystem parameter studies in conjunction with pollutant measurements; (4) the network be maintained for an indefinite period of time; (5) the network be established using the international biosphere reserve system as the universe from which a subset of monitoring sites are drawn; and (6) that the project be under the overall direction of the Global Environmental Monitoring System. 43 references, 1 figure, 1 table.

Warming systems prolong steam-turbine life, accelerate startup  

SciTech Connect (OSTI)

Cycling capability is one of the top challenges in the design, operation, and maintenance of today's powerplants. This article describes how permanent warming systems can be a powerful ally in meeting this challenge, particularly for aging steam turbines. The warming system is typically used to hold steam-turbine shell temperatures during short shutdowns (up to about three days), or to pre-warm shells after longer shut-downs. Permanent warming systems elevate metal temperature above 500 F, distinguishing them from heat tracing systems that operate at much lower temperatures for freeze protection or viscosity control. Permanent warming systems can reduced steam-turbine damage during both startup heating and off-line cooling, and can reduce plant startup time.

Sorption MechaniSMS for Mercury Sorption MechaniSMS for Mercury capture in WarM poSt-GaSification GaS clean-up SySteMS Background Power generation systems employing gasification technology must remove a variety of potential air pollutants, including mercury, from the synthetic gas steam prior to combustion. In general, efforts to remove mercury have focused on removal at lower temperatures (under 300 °F). The ability to remove mercury at warm-gas cleanup conditions (300 °F to 700 °F) or in the hot-gas cleanup range (above 1200 °F) would provide plant operators with greater flexibility to choose the treatment method best suited to conditions at their plant.
