Land O' Lakes: Melting Glaciers Transform Alpine Landscape


from Der Spiegel:





Climate change is dramatically altering the Swiss Alps, where hundreds of bodies of water are being created by melting glaciers. Though the lakes can attract tourists and even generate electricity, local residents also fear catastrophic tidal waves.

In the 1990s, the first cracks began to appear in the mighty tongue of the Trift Glacier in the central Swiss canton of Bern. In 2002, the peak of the ice mass burst into thousands of pieces. Since it lay in a hollow, the water swelled into a lake rather than flowing out. The Trift Lake then became an attraction: Hundreds of tourists per day now visit the suspension bridge that hangs over this new body of water. "Many more people come to the glacier than before," says Wilfried Haeberli of Zürich University.

The geographer and his colleagues calculate that, in the coming years, hundreds of such lakes will come into being in the Swiss Alps alone. In Austria, the Andes and other mountainous regions heavily affected by climate change, similar dramatic environmental transformations are occuring. "The rapid melting of glaciers is radically changing the Alpine landscape," Haeberli reported at the annual meeting of the European Geosciences Union (EGU) in Vienna. The ice region is in many places becoming a landscape of lakes.

New bodies of water would bring opportunities as well as risks. Tourists could take in something new, and reservoirs could supply hydroelectric power. Towns in these regions, however, see a looming danger: Avalanches threaten to tumble into the lakes, sending tidal waves that could be dozens of meters high surging down into the valley. ....................(more)
