Vanishing Joshua trees: climate change will ravage US national parks, study says

Park lands have warmed twice as fast as the rest of the country

America's national parks have warmed twice as fast as the US average and could see some of the worst effects of climate change, according to a new study.

Most of Joshua Tree national park could become uninhabitable for its eponymous trees, glaciers will continue to melt away at Glacier national park, and many other of America's most treasured beauty spots could be rendered virtually unrecognizable by climate change, Patrick Gonzalez, the lead author of the study, writes in the journal Environmental Research Letters.
