Providing hints that a reduction in coastal sea ice may make life difficult for polar bears, government biologists from Canada and the United States say they observed three instances of cannibalism among polar bears in a three-month stretch in 2004 along Alaskan and Yukon coasts. In the journal Polar Biology, the researchers said that no previous examples had been observed in the region in at least 24 years. Computer simulations project that the Arctic Ocean could become largely free of sea ice later in the century in summers if global warming intensifies

Oh, this can't be true. There's no such thing as global warming! Stupid NYtimes, being all political and making up stories.
