The U.S. Global Change Research Program (USGCRP) was established by Presidential Initiative in 1989 and mandated by Congress in the Global Change Research Act (GCRA) of 1990 to “assist the Nation and the world to understand, assess, predict, and respond to human-induced and natural processes of global change.”
The U.S. Global Change Research Program is a confederation of the research arms of 13 Federal departments and agencies, which carry out research and develop and maintain capabilities that support the Nation’s response to global change.
Interagency Working Groups (IWGs) are the primary USGCRP vehicles for implementing and coordinating global change research activities within and across agencies.
