America’s national parks are warming up and drying out much faster than the rest of the United States, according to a new study on the impacts of climate change on U.S. parks published in the journal Environmental Research Letters. The changing conditions are threatening protected ecosystems from the Everglades in Florida to Denali National Park in Alaska.
America’s national parks are warming up and drying out much faster than the rest of the United States, according to a new study on the impacts of climate change on U.S. parks published in the journal Environmental Research Letters. The changing conditions are threatening protected ecosystems from the Everglades in Florida to Denali National Park in Alaska.
The study found that the 417 protected areas in the U.S. national parks system warmed an average 1 degree Celsius (1.8 degrees Fahrenheit) between 1885 and 2010 — twice the average U.S. rate — with the most significant temperature increases happening in Alaska. Annual precipitation in parks, which cover a combined 85 million acres, declined 12 percent over the same period, compared to a 3 percent average drop across the U.S.
