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...

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 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...

Independent: Bears have been seen catching and eating dolphins for the first time ever, after the marine mammals were left stuck in the Arctic Ocean because of global warming. It marks the first time that bears have been seen killing and eating dolphins. Usually, the dolphins only go up north during the warmer summer -- but this year they have arrived in spring. The bears catch the dolphins in a similar way to the seals that they usually eat. Both animals keep holes in the ice which they use to come up...

Polar Bears to People: Momentum on Climate Change

Huffington Post: In the past several months, there has been much troubling news for all who are concerned about polar bears. Atmospheric CO2 concentrations hit 400 parts per million, higher than any time in perhaps 3 million years. The global average air temperature for all of 2014 was the highest on record. The maximum extent of Arctic sea ice this winter was the lowest ever recorded. My colleagues and I published papers showing that: land-based foods cannot sustain polar bears forced off the melting ice; the key...
