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 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, the U.S. Global Change Research Program (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.
