ANCHORAGE, Alaska (AP) - Some polar bears in the Arctic are shedding pounds during the time they should be beefing up, a new study shows. It's the climate change diet and scientists say it's not good.
They blame global warming for the dwindling ice cover on the Arctic Ocean that bears need for hunting seals each spring.
For their research, the scientists spied on the polar bears by equipping nine female white giants with tracking collars that had video cameras and the bear equivalent of a Fitbit during three recent springs. The bears also had their blood monitored and were weighed.
