Polar bears could vanish by the end of the century, scientists predict

Arctic sea ice has been steadily decreasing since the beginning of satellite records in 1979, but a new study comes with a chilling (or perhaps, warming) prediction: By the end of this century, Arctic sea ice may disappear during the summer, which could drive polar bears and other ice-dependent species to extinction.

The “Last Ice Area” is a region containing the oldest, thickest Arctic ice. It spans an area of more than 380,000 square miles (1 million square kilometers) from the western coast of the Canadian Arctic Archipelago to Greenland’s northern coast. When scientists named the 13-foot-thick (4 meters) ice region, they thought it would last for decades.
