From wildfires burning in Yosemite National Park, California, to glaciers melting in Glacier Bay National Park, Alaska, published scientific research has detected changes in United States national parks and attributed them to human-caused climate change. Since 1895, climate change has exposed the national parks to twice the heating of the country as a whole and to more severe aridity. Without cuts to pollution from cars, power plants, deforestation, and other human sources, continued climate change threatens the unique ecosystems, plants, and animals in parks. Meeting the Paris Agreement goal could lower projected heating by two-thirds, reducing risks of severe wildfire, disappearances of plants and animals, and other threats to our national parks.
