Today the U.S. Global Change Research Program released its Third National Climate Assessment.  The report which was overseen by the National Climate Assessment and Development Advisory Committee (NCADAC) was authored by over 300 experts and received over 4,000 public comments.  The report discusses how:

Climate change is already affecting the American people. Certain types of weather events have 2 become more frequent and/or intense, including heat waves, heavy downpours, and, in some 3 regions, floods and droughts. Sea level is rising, oceans are becoming more acidic, and glaciers 4 and arctic sea ice are melting. These changes are part of the pattern of global climate change, 5 which is primarily driven by human activity.

The 827 page report, is broken out into three main sections discussing: sectors (water; energy; transportation; agriculture; forests; ecosystems; human health; energy, water and land; urban; indigenous peoples; land use and land cover change; rural communities; and biogeochemical cycles); regions (Northeast, Southeast, Midwest, Great Plains, Southwest, Northwest, Alaska, Hawai’i and Pacific Islands, and Oceans & Coasts); and response strategies (Decision Support, Mitigation, Adaptation, Research Needs, and Sustained Assessment).
