 | Dawn strikes the mountains rising above St. Mary’s Lake in Montana’s Glacier National Park. When the park was created in 1910, it had 150 glaciers. Now there are 27. If warming trends continue, all those glaciers are likely to disappear in the next 25 years. “There are some things that are absolutely incontrovertible…: that greenhouse gases are increasing, that they are increasing because of human activity, that the planet is actually getting warmer, and that some part of that warming is due to greenhouse gases.”
