Alpine glaciers in retreat.

Swiss glaciers are melting away at an accelerating rate and many will vanish this century if climate projections are correct. The Rhone glacier has been a tourist attraction since the middle of the nineteenth century.
The scenic glacier next to the road over the Furka pass retreated dramatically over the past 150 years. Pictures from 1870 show the ice reaching to the village of Gletsch in the valley. Now the ice is almost 3 km further back disappearing behind the edge
of a 450 m high ice-polished slope. A lake is forming at the foot of the shrinking Rhone glacier.
