As world temperatures soar, public outcry has focused on the threat to polar ice sheets and sea ice. Yet there is another impact of global warming—one much closer to home—that spells trouble for Americans: the extinction of alpine glaciers in the Rocky Mountains. The epicenter of the crisis is Glacier National Park, Montana, whose peaks once held one-hundred-and-fifty glaciers. Only twenty-five survive. The Park provides a window into the future of climate impacts for mountain ranges around the globe.
Alpine glaciers have already begun to disappear worldwide: The Alps, Andes, Cascades, Rockies, and Himalayas are suffering staggering losses. Glaciers provide more than fifty percent of our freshwater needs worldwide—for drinking, irrigation, and hydroelectric power. What’s more, alpine ice feeds innumerable watersheds that harbor ecosystems crucial to fish and wildlife. Nowhere is this truer than in the mountains of Montana.
