Global Change Impacts & Adaptation

National Climate Assessments

Part of the US Global Change Research Program (USGCRP) charter is to conduct National Climate Assessments (NCA), which provides a report to the President and the Congress that evaluates, integrates, and interprets the findings of the federal research program on global change every four years. The National Climate Assessments act as a status report on climate change science and impacts. They are based on observations made across the country and compare these observations to predictions from climate system models. The NCA aims to incorporate advances in the understanding of climate science into larger social, ecological, and policy systems, and with this provide integrated analyses of impacts and vulnerability.

The Office of Research and Development's Global Change Research Program (GCRP) in the U.S. Environmental Protection Agency's (EPA) representative in the USGCRP. As such the GCRP participates in the USGCRP National Climate Assessments by providing stakeholder-oriented, assessments of the potential consequences of global change (particularly climate variability and change) on air quality, water quality, aquatic ecosystems, and human health in the United States. The tabs below represent the work that GCRP has done as part of the First and Second National Climate Assessment.

 USGCRP Regional Assessments

The publications and reports listed below represent the body of work that ORD's Global Change Research Program developed as part of the First National Climate Assessment.


 NCEA GCRP Supplemental Regional Assessments

The publications and reports listed below represent the supplemental work conducted by ORD's Global Change Research Program as follow up to the work done as part of the First National Climate Assessment. This information is not part of the First National Climate Assessment but is intended to further some of the research and findings that began during the First National Climate Assessment.
