USGCRP Global Climate Change Impacts in the US - Ecosystems

This report is one of seven sector-specific chapters from the United States Global Change Research Program's 2009 National Climate Assessment, "Global Climate Change Impacts in the U.S."   The 'Ecosystems' chapter presents current and projected impacts to ecosytems in the U.S. from climate change.  Ecosystem processes, migration seasons, species range and distribution shifts, extinction, desertification, and ocean acidification among other impacts are fully described relative to the effects of climate change. A brief example of adaptation is included demonstrating the preservation of coastal wetlands by preparing for sea-level rise. The benefits that ecosystems provide to society and the potential loss of these ecosystem services are also described.
