USGCRP Global Climate Change Impacts in the United States

This report from the U.S. Global Change Research Program (USGCRP) summarizes the science of climate change and its impacts on the U.S., now and in the future. The report includes climate change impacts by U.S. regions and sectors. The regions addressed include: Alaska, Coastal, Islands, Northwest, Southwest, Midwest, Northeast, and Southwest. The sector chapters include: agriculture, ecosystems, energy supply and use, human health, society, transportation, and water resources.

For more detailed information and direct links to each chapter, each sector report is represented individually in this clearinghouse. (Please see 'Global Climate Change Impacts in the U.S. - Agriculture' etc.) 

The report is intended to support policy and decision making at national and regional levels, pertaining to the reduction of greenhouse gas emissions and to the development of adaptation strategies that can help reduce or avoid some of the undesirable impacts of climate change.

The report draws from a large body of scientific information. The foundation of this report is a set of 21 Synthesis and Assessment Products (SAPs), which were designed to address key policy-relevant issues in climate science. In addition, other peer-reviewed scientific assessments were used, including those of the Intergovernmental Panel on Climate Change, the U.S. National Assessment of the Consequences of Climate Variability and Change, the Arctic Climate Impact Assessment, the National Research Council's Transportation Research Board report on the Potential Impacts of Climate Change on U.S. Transportation, and a variety of regional climate impact assessments.

Some adaptation options that are currently being pursued in various regions and sectors to deal with climate change and/or other environmental issues are identified in this report.
