Greenhouse gas emissions remain primary threat to polar bears
2015-07-03 17:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Greenhouse gas emissions remain the primary threat to the preservation of polar bear populations worldwide. This conclusion holds true under both a reduced greenhouse gas emission scenario that stabilizes climate warming and another scenario where emissions and warming continue at the current pace, according to updated U.S. Geological Survey research models. Under both scenarios, the outcome for the worldwide polar bear population will very likely worsen over time through the end of the century....

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...
Study: Polar bears could feel global warmings sting by 2025

Associated Press: About a third of the world`s polar bears could be in imminent danger from greenhouse gas emissions in as soon as a decade, a U.S. government report shows. The U.S. Geological Survey, the Interior Department`s research arm, said updated scientific models don`t bode well for polar bear populations across the world, especially in Alaska. The report released this week is part of the U.S. Fish and Wildlife Service`s recovery plan for the polar bear. It is expected to be published Thursday in the...
Polar bears are changing diet because of global warming study

Blue and Green: Researchers in Norway have spotted a polar bear eating a dolphin for the first time and have suggested that climate change is pushing the species further north in the Arctic region. Effects of warmer climate is making polar bears adapting to other preys that are not usually hunted, according to scientists in Norway, who published their findings in a new study. The team first saw a polar bear eating the carcasses of two white-beaked dolphins in the Norwegian Arctic in spring 2014. During the following...

Polar bears 'have started eating dolphins due to climate change'
2015-06-12 15:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Agence France-Presse: Polar bears have been spotted eating dolphins in the Arctic for the first time ever by Norwegian scientists, who believe global warming could have caused the bears to expand their diet. Polar bears feed mainly on seals but Jon Aars at the Norwegian Polar Institute has photographed dolphins being devoured by a bear and published his findings in the latest edition of Polar Research this month. "It is likely that new species are appearing in the diet of polar bears due to climate change because new...
