How do polar bears survive in the arctic environment?
They’re built for it! Polar bears love the Arctic climate, where winter temperatures can plunge to -45º C (-50º F). Polar bears are insulated by two layers of fur and a layer of blubber that can measure 11.5 cm (4.5 inches) thick. Their compact ears and small tail also prevent heat loss. In fact, polar bears have more problems with overheating than they do from the cold—especially when they run.
