Understanding global change is critical to our Nation’s welfare and economic vitality. USGCRP conducts state-of-the-art research to understand the interactive processes that influence the total Earth system—which includes the atmosphere, oceans, land, ice, ecosystems, and people.
Across America and around the world, people are making decisions to effectively minimize and prepare for global change. USGCRP creates a strong scientific foundation for informing and enabling these decisions.
Assessments are essential tools for linking science and decision making. USGCRP has a legal mandate to conduct a National Climate Assessment every four years, focused on climate impacts across the Nation now and in the future.
The long-term strength of U.S. global change research depends on close engagement with international efforts. USGCRP's international partnerships enhance scientific exchange and enable more informed, science-based decisions—domestically and globally.
