Due to the rapid melting of sea-ice, polar bears are becoming endangered. They are losing the habitat that they hunt, breed and den on. The melt off of the arctic last summer was equal to the size of Alaska, Texas and Washington state combined. This melting was not predicted to happen for another 30 years. This melting results in a shorter hunting season for polar bears and less polar bears. The best-studied population, Western Hudson Bay, has decreased by 22% since 1987.
This is all evidence that global warming is happening. Arctic ice is rapidly melting, temperatures are warming, and polar bear populations are decreasing.
