"The U.S. 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), which mandates development of a coordinated interagency research program.
Participants in the USGCRP include:
Agency for International Development
Dept. of Agriculture
Dept. of Commerce, Natl. Oceanic & Atmospheric Admin.
Dept. of Defense
Dept. of Energy
Dept. of Health and Human Services, National Institutes of Health
Dept. of State
Dept. of Transportation
Dept. of the Interior, US Geological Survey
Environmental Protection Agency
National Aeronautics & Space Administration
National Science Foundation
Smithsonian Institution.
The Office of Science and Technology Policy, the Office of Management and Budget, and the Council on Environmental Quality provide oversight on behalf of the Executive Office of the President."
