Polar bears are facing greater risk of starvation as Arctic ice melts and they endure longer ice-free seasons, researchers said in a study published Tuesday.
A new study finds that the animals are coping with the risk of starvation from global warming by swimming long distances and scavenging, but with little success
In a new study tracking the lives of polar bears near Churchill, Man., researchers aimed to find out what they live on during the summer. Some conserved energy while others scrambled for food, but nearly all lost weight raising concerns about starvation risks in the future as sea ice declines.
