Global Warming and the Polar Bear

A Polar bears prefer to live in extremely cold artic climates . They live only in the Northern Hemisphere , on the arctic ice cap , and they spend most of their time on coastal areas . Polar bears are widely

spread in Canada , extending from the northern arctic islands south to the Hudson Bay area . They are also found in Greenland , on islands off the shore of Norway , on the northern coast of the former Soviet Union , and on the northern and northwestern coasts of Alaska in the United States .

B The polar bear is the largest members of the bear family . Males Polar Bears stand from eight to 11 feet tall and generally weigh from 500 to 1,000 pounds , but can weigh as much as 1,400 pounds .

Female bears generally stand eight feet tall and weigh 400 to 600 pounds , except some , which can reach 700 pounds . The reason the polar bear weighs so much is that it stores about a four - inch layer of fat to keep it warm . The polar bear has a long , narrower head and nose , and small ears . It has coat that appears white but , each individual hair is actually clear and hollow . This helps the

polar bear keep warm . The polar bears coat helps it blend in with its snowy surroundings , this adaptation helps the Polar Bear hide while hunting . The polar bears front legs are slightly pigeon - toed , and fur covers the bottoms of its paws . These adaptations help polar bears keep themselves from slipping on ice .
