“In general, observations of cannibalism may be consistent with the idea that as bears become more nutritionally stressed due to sea ice loss —which there is evidence for in some parts of the Arctic —they will seek out alternative food sources,” Regehr said. “However, the bears [in this study] were all in pretty good body condition. A fat bear wouldn’t be very motivated to risk attacking another polar bear just for food. So, we should certainly be cautious in interpreting these observations and remain open to other explanations.”
Stirling agreed. “We do not have the information to separate those two possibilities.”
So, they were pretty much failing to practice science, just throwing blame out. And, even if true, it still wouldn’t prove AGW.
