CH Research Reports on Accelerating Melt of Canadian Glaciers

Research involving CH scientists has found that major glaciers in the Canadian Rockies are melting increasingly rapidly. This is primarily the result of a combination of less annual snowfall and higher temperatures in spring and summer, leading to the loss of multi-year snow or firn. Without this bright white insulating blanket, which has in the past helped to protect and preserve the glaciers through the warmer months, the ice absorbs greater amounts of solar energy and so melts more rapidly. Estimates from measurementys taken through the summer of 2016 suggest that around one metre of ice depth was lost every month, beginning several weeks earlier than usual as a result of early warm temperatures. This in turn does not bode well for water resources across the prairies through the growing seasons of years to come, as the major river systems rely largely on meltwater to maintain their flows.
