Experts: Most glaciers in Alps to vanish by 2050

Most glaciers will disappear from the Alps by 2050, scientists told a conference on climate change Monday, basing their bleak outlook on evidence of slow but steady melting of the region's continental ice sheets. Glaciers in western Austria's Alpine province of Tyrol have been shrinking by about 3 percent a year, meaning their mass decreases annually by roughly a meter (3 feet), said Roland Psenner of the University of Innsbruck's Institute for Ecology. "The average density of glaciers in the Alps is 30 meters (100 feet), so it seems rather certain that there won't be any more glaciers in the year 2050 except for a few high ones that lay above 4,000 meters (13,000 feet)," Psenner said.
