Ice thaw could spell bad news for polar bears
2013-02-14 20:07:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: A thaw of sea ice floating on the Arctic Ocean last year sent extra plant food to exotic creatures on the deep sea floor in a shift that might leave polar bears hungry at the surface, scientists said on Thursday. The study, using robot submarines down to 4,400 metres (14,400 ft) deep, could be a glimpse of radical changes for life in the sunless depths of the Arctic Ocean after ice thinned and shrank to cover a record low area in September 2012. Scientists found large amounts of algae growing...
Polar bears may require feeding by humans because of ailing ecosystem, researchers say

Toronto Star: Please feed the bears. That may be the new advice to heed after a dozen polar bear experts wrote a policy paper about the imminent problems facing the species due to rapid ecosystem changes in the Arctic. In every nature park, there are signs up saying dont feed the wildlife, said University of Albertas biologist Andrew Derocher, an expert on management of large Arctic mammals. Were not there yet, but we have to start looking at policy decisions and begin discussing options. Were...

Polar bears 'may need to be fed by humans'
2013-02-07 13:30:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: The day may soon come when some of the 19 polar bear populations in Canada, Alaska, Greenland, Norway, and Russia will have to be fed by humans in order to keep them alive during an extended ice-free season or prevent them from roaming into northern communities. Some bears may have to be placed in temporary holding compounds until it is cold enough for them to go back onto the sea ice. In worst-case scenarios, polar bears from southern regions may have to be relocated to more northerly climes that...

The Inconvenient Truth About Polar Bears
2013-02-02 20:36:00| Climate Ark Climate Change & Global Warming Newsfeed
National Public Radio: In 2008, reports of polar bears' inevitable march toward extinction gripped headlines. Stories of thinning Arctic ice and even polar bear cannibalism combined to make these predators into a powerful symbol in the debate about climate change. The headlines caught Zac Unger's attention, and he decided to write a book about the bears. Unger made a plan to move to Churchill, Manitoba, a flat, gray place on the Hudson Bay in northern Canada accessible only by train or plane. For a few months out...
