The province is long past the oppressive “heat dome” that caused cities to swelter last summer, but warmer temperatures this year had a lasting effect on the glacier that feeds Edmonton’s water supply. The Saskatchewan Glacier terminus saw 10 metres of thinning this year, said Brian Menounos, an earth sciences professor at the University of Northern British Columbia and Canada Research Chair in glacier change. It’s also the glacier that feeds the North Saskatchewan River, Edmonton’s sole source of drinking water.
