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...

Global Warming Will Open Arctic Shipping Routes
2013-03-07 13:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: Who said the effects of global warming are all negative? According to new research conducted by UCLA, melting sea ice during the late summer will make Arctic shipping channels much more accessible. The economy of the world depends on shipping as nearly all of a country's imports and exports are transported across the global by these large ships. Canals like the Suez and Panama have helped reduce the length of certain shipping routes, but nothing has been done in the Arctic region because of the...

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...

Melting Arctic Ice Will Make Way for More Ships and More Species Invasions
2013-03-06 17:29:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: The rare ships that have ventured through the harsh, icebound Arctic Ocean require reinforced hulls and ice-breaking bows that allow them to plow through dense ice as much as two meters deep, and face hazardous conditions in remote locations for long periods of time. Arctic sea ice now is melting so rapidly each summer due to global warming, however, that ships without ice-breaking hulls will be able to cross previously inaccessible parts of the Arctic Ocean by 2050. And light-weight ships equipped...
