Melting Glaciers Mean Double Trouble for Water Supplies
New research shows that as ice disappears, overall evaporation speeds up.

Mountain glaciers long have been known to be in retreat as the planet warms. But the process is occurring even more rapidly than previously believed, scientists said earlier this month in San Francisco at a meeting of the American Geophysical Union.
For example, said Garry Clarke, professor emeritus of glaciology at the University of British Columbia in Vancouver, Canada, the massive glaciers of Canada’s Saint Elias region, now comprised of nearly 98 cubic miles of ice (453 cubic kilometers), are likely to be cut in half by 2100, even under middle-of-the-road climate-change scenarios.
“[And] that’s the good news,” Clarke said.
In parts of the Canadian Rockies, he said, today’s glaciers will all but disappear completely, while others will shrink to remnants just 5 to 20 percent of their current size.
“We think that we will be witness over the next century mainly to the disappearance of the glaciers of western North America,” he said.](http://25.media.tumblr.com/tumblr_lwopu0D6sM1qe649zo1_500.jpg)
