LiveScience: Polar bears, the iconic victims of climate change, are shifting their migration patterns because of changes in sea ice. The bears are arriving on land earlier and departing later, a new study found, and it's threatening their access to food. A team of researchers studied the migration patterns of polar bears (Ursus maritimus) in Hudson Bay, Canada, using satellite-tracking data collected between 1991 and1997 and 2004 and 2009. They found that the rate at which sea ice melts and re-freezes, as...

Anchorage Daily News: It's long been known that the brown bears found on islands in Southeast Alaska are more closely related to polar bears than other brown bears. Now scientists wonder if they're a harbinger of what's to come for polar bears in the warming high Arctic. Researcher Beth Shapiro of the University of California in Santa Cruz told the Canadian Press the bears on Admiralty, Baranof and Chichagof islands (known as the ABC bears) appear to be descended from a polar bear population that got cut off from other...

He had to climb a ridge of sand to get to where the bear had last been seen, and when he got to the top he found it waiting on the other side. "I saw the black of its nose," he recalls.

Guardian: It all comes down, once again, to our old friend the precautionary principle. And, once again, the world has told our old friend to get stuffed. The 178 nations who make up the Convention on Trade in Endangered Species summit in Bangkok were essentially asked this question: is the future threat to polar bears from the rapid melting of sea ice by global warming so great that the additional pressure of hunting for rugs should be outlawed? The US, allied with Russia, argued yes, absolutely. They...
