The melting of Canada's glaciers is irreversible

New Scientist: See Canada's glaciers while you still can. Their melting is irreversible, according to projections based on real-world data and validated by satellite images. By the end of the century, a fifth of the Canadian ice sheet - the world's third largest - could be gone for good, raising average global sea levels by 3.5 centimetres. If the whole ice sheet melts, it would raise the global sea level by about 20 centimetres, a fraction of the 70 and 7 metre rises expected respectively if Antarctica and...

Canadian glaciers face 'big losses'
2013-03-07 16:11:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: The glaciers of the Canadian Arctic Archipelago will undergo a dramatic retreat this century if warming projections hold true. A new study suggests the region's ice fields could lose perhaps as much as a fifth of their volume. Such a melt would add 3.5cm to the height of the world's oceans. Only the ice of Greenland and Antarctica is expected to contribute more. The assessment is reported in the Geophysical Research Letters journal. "This is a very important part of the world where there...

Big Melt Expected for Canadian Arctic Glaciers
2013-03-07 15:44:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: A fifth of Canada's Arctic Archipelago glaciers may disappear by the end of the century, contributing 1.4 inches (3.5 centimeters) to sea-level rise, new research finds. For the study, published online Thursday (March 7) in the journal Geophysical Research Letters, scientists used computer models to predict how the glaciers would respond to future climate change. The results were not reassuring. "Even if we assume that global warming is not happening quite so fast, it is still highly likely that...

Canada's Arctic glaciers headed for unstoppable thaw: study
2013-03-07 12:12:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Canadian glaciers that are the world's third biggest store of ice after Antarctica and Greenland seem headed for an irreversible melt that will push up sea levels, scientists said on Thursday. About 20 percent of the ice in glaciers, on islands such as Ellesmere or Devon off northern Canada, could vanish by the end of the 21st century in a melt that would add 3.5 cm (1.4 inch) to global sea levels, they said. Governments are trying to understand every likely centimeter of sea level rise caused...

Canadian Arctic May Lose 20% of Glaciers by 2100, Study Shows
2013-03-07 09:37:00| Climate Ark Climate Change & Global Warming Newsfeed
Bloomberg: A fifth of Canadas Arctic glaciers may disappear this century, raising sea levels as their retreat becomes harder to reverse, scientists said. An increase in average global temperatures of 3 degrees Celsius (5.4 Fahrenheit) would be sufficient to melt the ice from glaciers on Canadas northern islands, according to a statement e-mailed today by the British Antarctic Survey, whose researchers contributed to the study. The Arctic has become a harbinger of climate change, with the effects of...
