U.S. Climate Impacts Report

June 2009 | Global Climate Change Impacts in the United States

This report, which confirms previous evidence that global temperature increases in recent decades have been primarily human-induced, incorporates the latest information on rising temperatures and sea levels; increases in extreme weather events; and other climate-related phenomena. It is the first such report in almost a decade to break out those impacts by U.S. region and economic sector, and the first to do so in such great detail.
