This report, prepared under the auspices of the President's National Science and Technology Council (NSTC), highlights the Program's recent research and describes future plans and goals. The U.S. Global Change Research Program (USGCRP) was established in 1989 and authorized by Congress in the Global Change Research Act of 1990. The first edition of Our Changing Planet was transmitted to the Congress as a supplement to the FY1990 budget. In just over a decade, the USGCRPhas generated remarkable improvements to our knowledge of Earth's global-scale environmental processes and helped identify and explain the causes and consequences of a series of global environmental changes, including ozone depletion and climate change.
