Polar bear paws (IMAGE) University of Washington Caption This photo shows the rear paws of a polar bear temporarily sedated for research in East Greenland in 2022. The bear has large chunks of ice frozen onto its feet, which the researchers removed. It is one of two polar bears showing this type of buildup, which appears to be a new phenomenon affecting some polar bears in the Far North.
