U.S. regional climate change impacts
• Northeast: agricultural production, including dairy, fruit, and maple syrup, will be increasingly affected as favorable climates shift.
• Southeast: accelerated sea-level rise and increased hurricane intensity will have serious impacts.
• Midwest: under higher emissions scenarios, reductions in Great Lakes water levels will impact shipping, infrastructure, beaches, and ecosystems.
• Great Plains: projected increases in temperature, evaporation, and drought frequency exacerbate concerns regarding the region's declining water resources.
• Southwest: water supplies will become increasingly scarce, calling for trade-offs among competing uses, and potentially leading to conflict.
• Northwest: salmon and other cold-water species will experience additional stresses as a result of rising water temperatures and declining summer streamflow.
• Alaska: thawing permafrost damages roads, runways, water and sewer systems, and other infrastructure.
• U.S. islands in the Caribbean and Pacific: climate changes affecting coastal and marine ecosystems will have major implications for tourism and fisheries.
• The nation's coasts: significant sea-level rise and storm surge will affect coastal cities and ecosystems around the nation; low-lying and subsiding areas are most vulnerable.
