In the WTF category: Polar bear cannibalism due to melting Arctic?

You know, there's only one of 19 polar bear populations verified to be climbing, most of the rest stable or declining.

A quick primer on polar bear ecology: It's backwards from you'd expect. They gain weight in winter, lose weight in summer. Why? Because their main diet is seal. They hunt them on the ice during the winter. Less ice, less opportunity to hunt.More global warming = less ice = less polar bears.

Now, it seems that desperate polar bears are eating their young around Hudson's Bay.

Nothing to see here folks...
