Title: Earth Systems Science and Engineering

Abstract

Providing the essential energy and water systems to support human needs while understanding and addressing their environmental consequences is a watershed problem for the 21st century. The LLNL Earth System Science and Engineering Program seeks to provide the scientific understanding and technological expertise to help provide solutions at both global and regional scales. Our work is highly collaborative with universities, laboratories and industrial partners across the world and involves observational data, laboratory experiments, and numerical simulations. The energy systems we have enjoyed for the last 100 years have resulted in the advanced standard of living in the developed world and a major emerging problem with climate change. Now we face a simultaneous realization that our reliance on fossil fuels is a source of conflict and economic disruption as well as causing potentially abrupt, even catastrophic global climate change. The climate and energy problem is perhaps the greatest challenge ever faced by mankind. Fossil fuel remains the least expensive and most available source of energy and the basis of our economy. The use of fossil fuels, especially over the last 100 years has led to a 30% increase in CO{sub 2} in the atmosphere. The problem is growing. The population ofmore » the Earth will increase by several billion people in the next 50 years. If economic growth is to continue, the demand for energy is estimated to approximately double in the next 50 years so that we will need approximately 10 TW more energy than the 15 TW we use now. Much of this demand will come from the developing world where most of the population growth will occur and where advanced energy technology is not generally used. The problem affects and is affected by a complex system of systems. The climate and energy problem will affect resources, social structure and the probability of increased conflict. No one person, no one nation, no one technology can solve the problem. There is no parallel precedent on which to model a solution. On these grounds, we have chosen to tackle four key tasks: (1) Understanding the natural Earth system and anthropogenic systems examining key forcings and processes driving these systems and the interactions between systems; (2) Identify climate change impacts important to society and develop strategies and technologies to adapt to the climate change that is inevitable given past, current, and potential emissions; (3) Developing strategies and technologies to reduce/eliminate greenhouse gas emissions thereby mitigating climate change while generating energy that is economically and socially viable; and (4) Engaging with appropriate economic, legal, social, and political structures to inform key decisions.« less

  • This project studied theoretical and practical methods for the categorization, analysis and synthesis of computing systems. In particular, an Emulation Laboratory was developed for the analysis of computer architectures and interpretive computer designs. A memory hierarchy management study developed techniques to improve the performance of multilevel virtual memory systems. Efforts in the areas of parallel processors and program representation continued, together with a newly initiated study on topology of algorithms. 1 figure.
  • Global Systems Science is an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand problems of global impact. The ``big ideas`` of science are stressed, such as the concept of an interacting system, co-evolution of the atmosphere and life, and the important role that individuals can play in both affecting and protecting our vulnerable global environment. The target audience for this course encompasses the entire range of high school students from s nine tough twelve. The course involves students actively in learning. Global Systems Science is divided into fivemore » volumes. Each volume contains laboratory experiments; home investigations; descriptions of recent scientific work; historical background; and consideration of the political, economic, and ethical issues associated with each problem area. Collectively, these volumes constitute a unique combination of studies in the natural and social sciences from which high school students may view the global environmental problems that they will confront within their lifetimes. Collectively, they constitute a unique combination of studies in the natural and social sciences through which high school students may view the global environmental problems that they will confront within their lifetimes. The five volumes are: A Planet Under Siege: Are We Changing Earths Climate; A History of Fire and Ice: The Earth`s Climate System; Energy Paths: Use and Conservation of Energy; Ecological Systems: Evolution and Interdependence of Life; and, The Case of the Missing Ozone: Chemistry of the Earth`s Atmosphere.« less

  • The major objective in the work funded under this contract was to continue work begun under the ONR contract N0014-82-K-0335 related to adaptive grid methods for engineering problems in fluid dynamics and the development of parallel algorithms for the same class of problems. Subjects treated include: Adaptive numerical methods for incompressible flow; Composite grid generation; Software systems for scientific computation; and Algorithm development for parallel computation.
  • The work explored the linking of modern developing machine learning techniques (manifold learning and in particular diffusion maps) with traditional PDE modeling/discretization/scientific computation techniques via the equation-free methodology developed by the PI. The result (in addition to several PhD degrees, two of them by CSGF Fellows) was a sequence of strong developments - in part on the algorithmic side, linking data mining with scientific computing, and in part on applications, ranging from PDE discretizations to molecular dynamics and complex network dynamics.
