Our Changing Planet: The FY 1993 U.S. Global Change Research Program. A Report bythe Committee on Earth and Environmental Sciences a Supplement to the U.S. President's Fiscal Year 1993 Budget

摘要

The USGCRP was established as a Presidential initiative in the FY 1990 Budget tohelp develop sound national and international policies related to global environmental issues, particularly global climate change. The USGCRP is implemented through a priority-driven scientific research agenda that is designed to be integrated, comprehensive, and multidisciplinary. It is designed explicitly to address scientific uncertainties in such areas as climate change, ozone depletion, changes in terrestrial and marine productivity, global water and energy cycles, sea level changes, the impact of global changes on human health and activities, and the impact of anthropogenic activities on the Earth system. The USGCRP addresses three parallel but interconnected streams of activity: documenting global change (observations); enhancing understanding of key processes (process research); and predicting global and regional environmental change (integrated modeling and prediction).
