They are also part of the cryospheric surface observation Years like this one will accelerate that dramatically and I think sooner or later we are going to have to issue death certificates for glaciers like they do in Iceland.

Ice stations have several data gaps, mainly in middle and upper ice station During the summer, significant amounts of glacial rock flour flow into the lake from Peyto glacier, and these suspended rock particles are what give the lake a unique bright, turquoise colour.

Few glaciers will remain in the interior and Rockies regions, the study concluded, while glaciers nearer the Pacific Ocean, particularly those in northwestern BC, would survive in a diminished state. The biggest loss, they predicted, would occur between 2020 and 2040, with potential implications of those reduced/depleted glaciers including impacts on aquatic ecosystems, agriculture, forestry, alpine tourism and water quality..
