Climate change: Canada glaciers to shrink by 70 per cent by 2100

The study, published in the journal Nature Geoscience, was headed by Garry Clarke, a professor at the University of British Columbia in Vancouver. The team used a computer model that combined four well-known scenarios for global warming this century, with data about three glacier-covered regions and dynamics of ice melt. Even at the lowest projected warming, most of the glaciers are essentially doomed, according to their forecast. "When the glaciers have gone, we lose the important services they provide: a buffer against hot, dry spells in late summer that keeps headwater streams flowing and cool, and sustains cool-water aquatic species."
