Annual polar bear migration underway: How climate change could be impacting it
2013-11-22 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
National Geographic: In the past month, hundreds of polar bears have strolled past a small town in Canada. It's part of their annual migration back to Hudson Bay, where sea ice is reforming after months of summer melt. To get to the ice each autumn, they traverse Churchill, Manitoba-the "polar bear capital of the world." These animals are the most studied group of polar bears on Earth. The renowned Ian Stirling, now retired from the Canadian Wildlife Service, began his groundbreaking research here 40 years ago....
Canada refusal protect polar bears comes under scrutiny

Guardian: Canada's closest allies and neighbours have called for a formal investigation into the government's refusal to offer full protection to polar bears threatened with extinction because of climate change. The secretariat of the Central Environmental Commission (CEC) said this week there were "central open questions" about Canada's decision to offer only limited protection to polar bears. The CEC, which was set up by America, Canada, and Mexico under the North America free trade agreement, went on...

Climate change threatening polar bears in Canada
2013-11-14 01:30:00| Climate Ark Climate Change & Global Warming Newsfeed
NBC News: Polar bears currently outnumber the residents of a small town in Canada's tundra, but that may change soon. Climate change has sped up the ice melting season in Churchill, Manitoba, a town of about 800 residents -- and 900 polar bears. Experts say the perennial thaw now begins in mid-June, a full 30 days earlier than three decades ago, which means the polar bears spend more time on land. It also means the bears are eating less and birthing smaller cubs that are not as likely to survive. Scientists...

'Missing Heat' Discovered Hiding Out in Polar Regions, Africa
2013-11-13 22:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Researchers say they have uncovered the climate system's "missing heat" and, in so doing, have punched a hole in the argument that global warming has slowed or even stopped altogether during the last 15 or so years. Following decades of a steady, upward march, global temperatures suddenly stagnated back in the late 1990s. However, the study notes, climate records are based on observational data that only accounts for 84 percent of the planet. The Polar regions and Africa are largely excluded,...

Polar bear attacks: scientists warn of fresh dangers in warming Arctic
2013-11-04 08:44:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: A polar bear attack in Canada that left two people injured has brought new warnings from scientists of a dangerous rise in human-bear encounters in a warming Arctic. The friends had just walked out of the door in the pre-dawn hours after a party when the young polar bear crept up behind them, unheard and unseen. By the time, the bear was driven off by neighbours wielding a shovel, banging pots and pans, and firing multiple rounds from a shotgun, two people were badly mauled: the young woman...
