Much of the research on the interactions of natural and human-induced changes in the global environment and the implications for society is coordinated by the United States Global Change Research Program (USGCRP). The USGCRP was established through a presidential initiative in 1989 as a multiagency effort to:

  • develop and coordinate a comprehensive and integrated program to increase the effectiveness and usefulness of government-supported global change research;

  • address scientific uncertainties about natural and human-induced Earth system changes;
