Climate change in mountain regions

Climate change is a reality today, and some of the best evidence comes from mountain areas: over the last century, glaciers in the European Alps and the Caucasus Mountains have shrunk to half their size, while in Africa only 8 percent of Mount Kenya's largest glacier remains. If current trends continue, by the end of this century many of the world's mountain glaciers, including all those in Glacier National Park in the United States, will have vanished entirely.
