"The United States Global Change Research Program (USGCRP) supports research on the interactions of natural and human-induced changes in the global environment and their implications for society. The USGCRP began as a Presidential initiative in 1989 and was codified by Congress in the Global Change Research Act of 1990 (P.L. 101- 606). The statute directs the implementation of a program aimed at 'understanding and responding to global change, including the cumulative effects of human activities and natural processes on the environment.' On June 11, 2001, President Bush announced the establishment of the U.S. Climate Change Research Initiative to study areas of uncertainty and identify priority areas for investment in climate change science. The definition of this new initiative is underway, and is expected to lead to changes in USGCRP climate research activities in FY 2003 and beyond. These changes will be highlighted in the next annual report of the USGCRP."
