Canary in the coal mine – national parks

David Frey: National Parks are a climate change canary. National parks across the country are facing landscape-altering changes at the hands of global warming. Most famous is the melting ice at Glacier National Park in Montana. The question at hand is: How long will it be until that name is a misnomer? How long until those beautiful glaciers are gone for good? Not long.
