Abstract

The distribution and abundance of Sphagnum spores in North America and Eurasia are mapped for the past 21ka, as described in Gajewski et al. (2002). In summary, spore data were taken from existing pollen data bases, as were radiocarbon chronologies. The abundance of Sphagnum spores was mapped at 2000-year intervals beginning 21000 years BP (before present). The present-day distribution of abundant Sphagnum spores corresponds closely to areas with peatland development, with maximum Sphagnum abundance between 630 and 1300 mm annual precipitation and between -2° and 60°C mean annual air temperature. Carbon content of peatlands was generated from estimated peatland area, calculated values of peat thickness, and specified values of bulk density (112 × 103-3) and fraction of carbon (51.7%).To access the older version of this data package see: http://cdiac.ess-dive.lbl.gov/trends/ecosystems/gajewski2.html

Simulated precipitation changes in Central Asia since the Last Glacial Maximum

Journal Article Zhang, Xiaojian ; Li, Jiarui ; Gao, Meng ; ... - Quaternary International

According to the article, the availability of freshwater has been and remains a crucial concern in westerlies-dominated arid Central Asia. Understanding precipitation changes in this area and the underlying mechanisms, therefore, is of great importance. This study explores precipitation changes in Central Asia (35°–50° N and 50°–70° E) since the Last Glacial Maximum (LGM) and their control factors using results from the “Simulation of Transient Climate Evolution over the last 21,000 years”. Transient simulations reveal that a wet climate occurred during the LGM, the Bølling-Allerød warm period, and the middle Holocene, and a dry climate occurred during Heinrich event 1,more »« less
Biochemical bases for the biogeography of C3/C4 grasses and implications for changing distributions since the last glacial maximum

Journal Article Collatz, G J ; Clark, J S ; Berry, J A - Bulletin of the Ecological Society of America

Differential distributions of C3 and C4 grass taxa correlate with geographic and climatic factors. A simple model based on the temperature dependence of the photosynthetic quantum yield of C3 plants and the lack of response of the C4 quantum yield to temperature is used to predict the global distribution of C4 grasses at current atmospheric CO2 concentrations and climate. The model predicts a cross over temperature at which the quantum yield responses intersect; at temperatures above the cross over point C4 grasses are favored over C3. The cross over temperature is about 22{degrees}C at current atmospheric CO2 concentrations. Using thismore »« less

Modeling precipitation δ¹⁸O variability in East Asia since the Last Glacial Maximum: temperature and amount effects across different timescales

Journal Article Wen, Xinyu ; Liu, Zhengyu ; Chen, Zhongxiao ; ... - Climate of the Past (Online)

Water isotopes in precipitation have played a key role in the reconstruction of past climate on millennial timescales and longer. But, for midlatitude regions like East Asia with complex terrain, the reliability behind the basic assumptions of the temperature effect and amount effect is based on modern observational data and still remains unclear for past climate. In the present work, we reexamine the two basic effects on seasonal, interannual, and millennial timescales in a set of time slice experiments for the period 22–0 ka using an isotope-enabled atmospheric general circulation model (AGCM). Our study confirms the robustness of the temperaturemore »« less
