With a warmer climate, the sea ice is melting and more species are moving to northern latitudes. For killer whales, the melting sea ice provides new roaming opportunities further north into the Arctic Ocean.
When the polar bears are forced to spend more time on land than on the ice, the risk of them starving to death increases, a new study shows. This shows, say the researchers, that Polar Bears will find it difficult to adapt to a changing climate with warmer summers. "Polar bears are not grizzly bears wearing white coats. They're very, very different." said Charles Robbins, director of the Washington State University Bear Center and co-author of the study in the journal Nature Communications.
