How climate change could spell the end of America's Yellowstone Park

Yellowstone National Park: On a recent northern autumn afternoon in the Lamar Valley, visitors watched a wolf pack lope along a thinly forested riverbank, 10 or so black and grey figures shadowy against the snow. A little further along the road, a herd of bison swung their great heads as they rooted for food in the sagebrush steppe, their deep rumbles clear in the quiet, cold air.
