Climate change taking big bite out of alpine glaciers

Across the Alps, glaciers have lost half their volume since 1900. And there is no letting up: Melting has accelerated since 1980. Most Alpine glaciers will be gone by the end of this century, scientists say. There is already enough heat-trapping pollution in the air to melt nearly all the ice, even if greenhouse gas emissions are cut to zero immediately, said climate physicist Carl-Friedrich Schleussner, who works as a scientific advisor for the NGO Climate Analytics.
