Causes of twentieth-century temperature change near the Earth's surface
Article Abstract:
Temperature changes during the past 30-50 years are unlikely to be due entirely to internal climate variability, and are attributed to greenhouse gases and sulphate aerosols from human activities. A coupled atmosphere-ocean general circulation model was used to study the patterns of time/space changes in near-surface temperature. Solar forcing may have contributed to temperature changes early in the century, although a combination of anthropogenic causes and natural variability may also be a possible explanation. Anthropogenic components were largely responsible for the warming between 1946 and 1996.

Nearly synchronous climate change in the Northern Hemisphere during the last glacial termination
Article Abstract:
Evidence of four major hydrological oscillations in the Owens basin, California, occurring during the last glacial termination, is presented, using accelerator mass spectrometry dates on bulk organic carbon. The observations support recent climate simulations which suggest that cooling of the North Atlantic Ocean leads to cooling of the North Pacific Ocean, resulting in a drier climate in western North America.

Quantifying the uncertainty in forecasts of anthropogenic climate change
Article Abstract:
Research is presented concerning the forecasting of global climate change between 2000 and 2050. The influence of human activities on global warming and the difficulty of accurately predicting temperature changes are discussed.
