A 3D computer simulation, released this week as part of a study into the glaciers of British Columbia reveal how much impact the changing climate could have on the region. Garry Clarke, professor emeritus at the University of British Columbia who co-authored the report, says that melting glaciers will change the amount of water delivered to the salmon-spawning beds and shatter visions of future ski resorts. It estimates that by 2100 the glaciers in the Rocky Mountains will be almost gone with the Columbia Mountains also suffering badly. The southern coast mountains and those in the northwest near the Yukon and Alaska borders should survive the study says. While the new simulation is a stark warning of what could occur there is a positive note; it shows that if climate change stabilizes the glacier melt could be less dramatic and outlast the predictions.
