Glaciers' wane not all down to humans : Nature News

Is it all down to man-made global warming? Not according to a recent study, which finds that about half of the glacier loss in the Swiss Alps is due to natural climate variability — a result likely to be true for glaciers around the world.

"This doesn't question the actuality, and the seriousness, of man-made climate change in any way," says Matthias Huss, a glaciologist at the University of Fribourg in Switzerland, who led the study. "But what we do see is that current glacier retreat might be equally due to natural climate variations as it is to anthropogenic greenhouse warming."
