Seventy per cent of glacier ice in British Columbia and Alberta could disappear by the end of the 21 st century, creating major problems for local ecosystems, power supplies, and water quality, according to a new study by UBC researchers.
The study found that while warming temperatures are threatening glaciers in Western Canada, not all glaciers are retreating at the same rate. The Rocky Mountains, in the drier interior, could lose up to 90 per cent of its glaciers. The wetter coastal mountains in northwestern B.C. are only expected to lose about half of their glacier volume.
"Most of our ice holdouts at the end of the century will be in the northwest corner of the province," said Garry Clarke, professor emeritus in the Department of Earth, Ocean and Atmospheric Sciences. "Soon our mountains could look like those in Colorado or California and you don't see much ice in those landscapes." ...[Continue reading on UBC News]
