The melting of the Great Aletsch glacier
The project is part of a serie for Reuters and its clients called "Earthprints" that look at the impact of Global Warming at 10 selected places around the world We went on and around the Great Aletsch glacier, one of Europe's biggest glaciers, that coils 23 km (14 miles) through the Swiss Alps - and yet this mighty river of ice could almost vanish in the lifetimes of people born today because of climate change. The glacier, 900 metres thick at one point, has retreated about 3 km since 1870 and that pace is quickening. Andreas Vieli, a professor who heads the University of Zurich's group of glaciology experts, said the Aletsch may lose 90 percent of its ice volume by 2100, with the lower reaches melting away.
