Between 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew from an average of three gigatons to 30 gigatons
The Greenland Ice Sheet isn’t the only place melting under a thickening blanket of heat-trapping greenhouse gases. A new study shows that Canada’s Arctic glaciers are also shedding ice at a rapidly increasing rate, making them a big factor in global sea level rise.
In a new study, glaciologists with the University of California, Irvine said that, between 2005 to 2015, surface melt off ice caps and glaciers of the Queen Elizabeth Islands grew by 900 percent, from an average of three gigatons to 30 gigatons per year, according to findings published last week in the journal Environmental Research Letters.

Modeling projects huge economic losses in fisheries
A fine-grained look at climate change impacts in Canada suggests that coastal First Nations people might be hit especially hard, with fisheries catch potentially declining by 50 percent in the next few decades. That represents losses between $6.7 and $12 million annually by 2050.
Alaska communities seek international review of Canadian projects that will affect their rivers
FRISCO — Mining and energy development in western Canada is making some Alaskans uneasy, as they eye potential impacts to pristine salmon streams in the region.
Citing a bilateral environmental treaty, activists this week will meet with British Columbia’s Minister of Energy and Mines, Bill Bennett, when he visits Juneau and will ask him to support an international review of mine developments in northwest B.C.
FRISCO — The toxic legacy of acid rain lives on in lakes in Canada, and possibly other places around the world, according scientists who say they’ve traced a trend of reduced calcium levels leading to a “jellification” of some lakes.
Specifically, the changes in water chemistry have reduced populations of calcium-rich plankton such as Daphnia — water fleas that dominate these ecosystems. Falling calcium levels mean Daphnia cannot get the nutrients they need to survive and reproduce, leading to a rise in other plankton species, including small jelly-clad organisms.
FRISCO — A seldom-used environmental provision of the North American Free Trade Agreement may help shed light on the Canadian government’s baffling stance on polar bear conservation.
Despite the growing threat from melting Arctic ice, the polar predators have only been awarded a low level of protection under Canadian environmental laws, triggering a petition process to the Secretariat of the Commission for Environmental Cooperation.
