4 Ways Polar Bears Are Dealing With Climate Change

National Geographic: It's a tough time to be a polar bear. The Arctic predatorswhich depend on constantly diminishing amounts of sea ice to catch marine mammals such as sealsare declining in number, and fast. There are fewer than 25,000 polar bears left in the wild, according to the nonprofit organization Polar Bears International. Near the southern Beaufort Sea (map), for instance, the population has dropped about 40 percent between 2001 to 2010, from 1,500 to 900 bears. And as their habitat shrinks, they've have...

Polar bears are in more trouble than we thought
2015-07-19 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Quartz: Polar bears have been a face of climate change for years. We`ve long understood that the melting sea ice is drastically reducing their means of foraging for seals, their main food source. We even know that pollution puts their penile bone density at risk. But now, scientists have identified another threat to polar bears: Summer ice melt. Researchers from the University of Wyoming found (paywall) that polar bears aren`t able to adapt to low food supplies by reducing their metabolisms during...
Polar bears can't adapt melting Arctic, will waste away

InsideClimate: Polar bears have been one of the species hit hardest by climate change over the last decade, experiencing population declines up to 40 percent in some areas. Even so, scientists have long held out hope the mammals might adapt in some way to their melting Arctic habitat and reboundor at least stabilize in numbersas the world continues to warm. But new research published Thursday in the peer-reviewed journal Science deals a blow to that optimism. Eight U.S.-based scientists tested a leading hypothesis...
What's the future of polar bears? Studies say they may soon be extinct

Christian Science Monitor: Polar bears could soon be extinct due to global warming, says a recently released government report. According to the report, which is part of the US Fish and Wildlife Service's recovery plan for the polar bear, approximately a third of all polar bears could face imminent danger from greenhouse gas emissions in as little as 10 years. "Polar bears are in big trouble," Rebecca Noblin, Alaska director for the Center for Biological Diversity, told the Associated Press. "There are other steps we...

Polar bears will die out if global warming is not reversed, US report finds

Independent: Polar bears will be wiped out if humans don't reverse the trend of global warming, according to a blunt report by the US goverment. In a draft recovery plan for polar bears produced by the US Fish and Wildlife Service, it says: "The single most important step for polar bear conservation is decisive action to address Arctic warming." "Short of action that effectively addresses the primary cause of diminishing sea ice, it is unlikely that polar bears will be recovered." Polar bears eat, mate and...
