As ice melts, polar bears migrate north

Washington Post: It was just a theory, but for years scientists believed what years of observation was telling them. As Arctic sea ice melted because of climate change, polar bears appeared to be inching their way toward a final refuge in the icy Canadian archipelago. Now a new study of polar bear DNA backs that up. Scientists who research the animals across the Arctic teamed up to produce a paper showing that the "directional gene flow" of recent polar bear generations is "moving towards areas with more persistent...

Warming leads to more run-ins with polar bears

Agence France-Presse: Word spread quickly: a polar bear, then two, were spotted near this remote Inuit village on the shores of Hudson Bay, about 1,800 kilometers (1,120 miles) north of Montreal. Children were whisked indoors. Hunters armed with rifles set out from Kuujjuarapik on snowmobiles in a blizzard to kill the intruders, before the bears could get close enough to take a bite out of any of the town's 1,500 residents. Clashes between bears and people so far south of the Arctic were unheard of a century ago....

Canadas High Arctic polar bears running out of time
2014-12-08 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Edmonton Journal: Until this year, Andrew Derocher was convinced Canadas High Arctic islands, where the sea so far remains frozen, would always support some polar bears while populations declined elsewhere. But a new study modelling melting sea ice shows that wont likely be the case, says the University of Alberta professor and Canadas foremost expert on polar bears. Its pretty clear, by the end of the century all those areas will have problems sustaining a population of polar bears, Derocher said in an interview...
No Refuge for Polar Bears in Canadian Archipelago
2014-12-01 18:01:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: When habitat is free of sea ice for 180 days, for instance, it's estimated that 9 to 21 percent of adult male polar bears face starvation, with other ages and classes being more vulnerable. Polar bears could face mass starvation and reproductive failure across the entire Canadian archipelago by the end of the century, suggesting an area once considered a last refuge for the animals may no longer be a very good one, according to a new study. While polar bears have long been the poster child...
