The US Global Change Research Program today released the National Climate Assessment. The Assessment summarizes the impacts of climate change on the United States. Ecosystems Center Distinguished Scientist Jerry Melillo chaired the 60-member Federal Advisory Committee that produced the report. The Assessment was produced by a team of more than 300 experts and was extensively reviewed by the public and experts, including the National Academy of Sciences.
The Assessment unequivocally states that climate change is happening now. The U.S. and the world are warming, global sea level is rising, and some types of extreme weather events are becoming more frequent and more severe. These changes have already resulted in a wide range of impacts across every region of the Nation, its ecosystems and many sectors of the economy.
