Polar bears weakened by pollution as well as warmth

Daily Climate: Greenlands polar bears have a thyroid problem. Their endocrine systems, too, are being disrupted. In both cases the culprit agency is environmental pollution by a range of long-lived industrial chemicals and pesticides. Kristin Mller Gabrielsen of the Norwegian University of Science and Technology in Trondheim and colleagues report in the journal Environmental Research that they examined the liver, muscle and kidney tissues taken from seven polar bears killed by Inuit hunters in East Greenland...

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...
Canadas High Arctic polar bears running out of time

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...
