The U.S. Global Change Research Program (USGCRP) is a Federal program mandated by Congress to coordinate Federal research and investments in understanding the forces shaping the global environment, both human and natural, and their impacts on society.
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.”
USGCRP comprises 13 Federal agencies that conduct or use research on global change and its impacts on society, in support of 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.
The USGCRP budget crosscut represents funds self-identified by agencies as their contributions to USGCRP research.
Since 1989, USGCRP has submitted annual reports to Congress called Our Changing Planet. The reports describe the status of USGCRP research activities, provide progress updates, and document recent accomplishments.In particular, Our Changing Planet highlights progress and accomplishments in interagency activities. These highlights represent the broad spectrum of USGCRP activities that extend from Earth system observations, modeling, and fundamental research through synthesis and assessment, decision support, education, and public engagement.
