Where do Siberian polar bears live?
Polar bears live in Alaska, Canada, Russia, Greenland, and some northern islands owned by Norway, such as Svalbard. Polar bears depend on the sea ice, which forms above the open waters where their seal prey lives.
What do polar bears need to survive in their habitat?
Inhabiting the ice and sea of the Arctic, polar bears are well-equipped for survival in a harsh environment. Two coats of fur and a thick layer of blubber help insulate the polar bear’s body from the cold, keeping its temperature at an even 37° C (98.6° F).
Are there polar bears in Anchorage?

What do polar bears need to survive?
Polar bears need thermoregulation, because they want to survive in this extreme temperature. “Body temperature, which is normally 37C (98.6F), is maintained through a thick layer of fur, a tough hide, and an insulating layer of blubber. This excellent insulation keeps a polar bear warm even when air temperatures drop to -37C (-34F)” (sea- world).
Why are polar bears becoming extinct?
Polar bears are in serious danger of going extinct due to global warming. The bears were the first vertebrate species to be listed by the U.S. Endangered Species Act as threatened by extinction primarily because of global warming.
What is happening to polar bear habitat?
In all cases, the primary conservation concern for polar bears is habitat loss and reduced access to their seal prey due to climate change. Scientists predict that as the Arctic continues to warm, two-thirds of the world’s polar bears could disappear within this century.
