Climate change a factor in whitebark pine extinction threat
The U.S. Fish and Wildlife Service has determined that whitebark pine faces an "imminent" risk of extinction because of factors including climate change. This is the first time the federal government has identified climate change as one of the driving factors for why a broad-ranging tree species could disappear. A recent study found that 80% of whitebark pine forests in the Greater Yellowstone ecosystem are dead or dying.
