Polar Bear Attacks: Scientists Warn of Fresh Dangers in Warming Arctic

"CHURCHILL, Manitoba -- A polar bear attack in Canada that left two people injured has brought new warnings from scientists of a dangerous rise in human-bear encounters in a warming Arctic."

"The friends had just walked out of the door in the pre-dawn hours after a party when the young polar bear crept up behind them, unheard and unseen.

By the time, the bear was driven off by neighbours wielding a shovel, banging pots and pans, and firing multiple rounds from a shotgun, two people were badly mauled: the young woman who was the original target of the attack and an older male neighbour who tried to come to her rescue."
