14 Apr 2015: Canada Could Lose 70 Percent
Of Glaciers by End of Century, Study Finds

British Columbia and Alberta could lose 70 percent of their glaciers by the end of the 21st century, creating major problems

for local ecosystems, power supplies, and water quality, according to a study in Nature Geoscience. Wetter coastal mountain regions in northwestern British Columbia are expected to lose about half of their glacial volume, the researchers found, but the Rocky Mountains, in the drier interior portion of Canada, could lose 90 percent of their glaciers. “Soon our mountains could look like those in Colorado or California and you don’t see much ice in those landscapes,” said Garry Clarke, lead author of the study. Alberta and British Columbia have more than 17,000 glaciers and they play an important role in hydroelectric power production. The glaciers also contribute to the water supply, agriculture, and tourism, but the greatest impact of their loss could be on freshwater ecosystems, the researchers say. During the late summer, glacial melt provides cool, plentiful water to many of the region’s headwaters, acting as a thermostat for freshwater ecosystems, Clarke notes.
