Without action on climate change
Scientists predict we could lose wild polar bears by 2100. Polar bears roam the Arctic ice sheets and swim in that region's coastal waters.
They are very strong swimmers, and their large front paws, which they use to paddle, are slightly webbed.
Some polar bears have been seen swimming hundreds of miles from land—though they probably cover most of that distance by floating on sheets of ice.
Arctic Adaptations
Polar bears live in one of the planet's coldest environments and depend on a thick coat of insulated fur, which covers a warming layer of fat.
Fur even grows on the bottom of their paws, which protects against cold surfaces and provides a good grip on ice. The bear's stark white coat provides camouflage in surrounding snow and ice.
But under their fur, polar bears have black skin—the better to soak in the sun's warming rays.

Polar bears are the largest carnivorous land mammals on Earth.
They are about seven to eight feet long, measured from the nose to the tip of their very short tail.
Male Polar bears are much larger than the females.
A large male can weigh more than 1,700 pounds, while a large female is about half that size (up to 1,000 pounds).
