The United States Global Change Research Program.
"The U.S. Global Change Research Program (USGCRP) is mandated by the Global Change Research Act of 1990. Thirteen departments and agencies participate in the USGCRP, which was known as the U.S. Climate Change Science Program from 2002 through 2008. The program is steered by the Subcommittee on Global Change Research under the Committee on Environment and Natural Resources, overseen by the Executive Office of the President, and facilitated by an Integration and Coordination Office."
