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...
Schools, offices shut as typhoon bears down on Philippines

Reuters: Schools and government offices were shut in parts of the central Philippines on Thursday and residents stocked up on supplies and food, as provinces yet to recover from last year's devastating super-typhoon Haiyan braced for another category 5 storm. Typhoon Hagupit was churning across the Pacific around 860 km (585 miles) east of the island nation on Thursday, the local weather bureau said, packing winds of up to 195 kph (120 mph) with gusts of up to 230 kph. It was expected to strengthen...

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...

Polar bears facing 'worst-case trajectory' because of climate change
2014-11-27 00:39:00| Climate Ark Climate Change & Global Warming Newsfeed
Toronto Star: Even the High Arctic wont remain a haven for polar bears if the Earth continues to warm at the current pace, says an alarming new study. Published in PLOS One, an online science journal on Wednesday, the study warns that all regions of Canadas Arctic islands could potentially be ice-free for two to five months every year by the end of the century, triggering starvation and reproductive failure for polar bears. Conditions outside the islands could be worse for the bears. It doesnt look...

Shrinking Sea Ice Could Put Polar Bears In Grave Peril By 2100
2014-11-26 22:53:00| Climate Ark Climate Change & Global Warming Newsfeed
National Public Radio: A new study looks at the future of the Canadian Arctic Archipelago and finds that by the end of this century, the region might be ice-free for 2 to 5 months, something that puts bears in grave peril.
