Historical and projected climate change trends for the United States and U.S. national parks

Research published in Environmental Research Letters examined historical and projected trends in anthropogenic climate change for the United States and all 417 U.S. national parks. Results show that temperature in the national park area increased at double the U.S. rate from 1895 to 2010 and precipitation decreased on a greater fraction of the national park area than the U.S. as a whole. Continued climate change could expose a greater fraction of national park area to projected temperature increases >2°C, the upper limit of the Paris Agreement goal. The data page includes GeoTiff files of historical and projected climate change trends for the 50 U.S. states, the District of Columbia, American Samoa, Guam, Puerto Rico, and the U.S. Virgin Islands and a data table with individual results for each of 417 national parks.
