Polar Bears Appear Where They Never Were Before

Polar bears have been rummaging through science camps at the top of Greenland's ice sheet far inland, where they were never expected, and Polar bears are coming into communities more often these days, says Kristin Laidre, a marine biologist at the University of Washington’s Polar Science Center, and an authority on polar bear populations in Greenland. “It’s happening all over the Arctic, and it’s something that’s only going to be an increasing problem as we continue to lose sea ice,” she says.
