Polar Bear Status Report

This map by the Norwegian Polar Institute shows the status of the 19 polar bear subpopulations according to the latest IUCN Polar Bear Specialist Group report: 3 are declining, 6 are stable, 1 is increasing, and 9 have insufficient data to make a determination. Details...

Polar Bear Status Report

Scientists don't have solid figures on the number of polar bears worldwide because they lack data on some populations (see map above). This is because many polar bears live in remote areas that are difficult to survey.

However, biologists estimate there are roughly 20,000 to 25,000 polar bears. About 60% of those live in Canada. Polar bears are also found in the U.S. (Alaska), Russia, Greenland, and Norway (Svalbard).

Conservation status. In May 2008, the U.S listed the polar bear as a threatened species under the Endangered Species Act, citing sea ice losses in the Arctic from global warming as the single biggest threat to polar bears. Polar bears depend on sea ice for hunting, breeding, and in some cases, denning. 

The IUCN Polar Bear Specialist Group also lists sea ice losses from a warming Arctic as the biggest threat to polar bear survival. At their 2014 meeting, scientists reported that of the 19 populations of polar bears:

  • 3 are declining
  • 6 are stable
  • 1 is increasing
  • 9 have insufficient data

Current Trends of the World's 19 Populations 

Declining Stable Increasing Data deficient
Baffin Bay Davis Strait  M'Clintock Channel Arctic Basin
Kane Basin  Foxe Basin    Barents Sea
S. Beaufort Sea Gulf of Boothia    Chukchi Sea 
  N. Beaufort Sea   East Greenland 
  S. Hudson Bay   Kara Sea 
   W. Hudson Bay   Lancaster Sound
      Laptev Sea 
      Norwegian Bay 
      Viscount Melville Sound

 Results from long-term studies show:

  • Canada's Western Hudson Bay population: 22% decline since the early 1980s, directly related to longer ice-free seasons on Hudson Bay.
  • Southern Beaufort Sea population along the northern coast of Alaska and western Canada: plunged by about 40% over a 10-year study period from 2001-2010, dropping from about 1500 bears to 900 bears. 
  • Baffin Bay population, shared by Greenland and Canada: at risk from both significant sea ice loss and substantial over-harvesting.

Scientists predict that unless we take action to stop climate change, we could lose two-thirds of all polar bears by the middle of the century and all of them by the end of the century. Visit the Polar Bear Specialist Group's website for a summary on each population's status.

But some people are seeing more bears!

Some northern communities are reporting an increase in the numbers of polar bears on land. They believe this means an increase in population. Scientists attribute it to polar bears being driven ashore by lack of ice.

The U.S. Fish and Wildlife Service states, ". . . extensive scientific studies have indicated that the increased observation of bears on land is a result of changing distribution patterns and a result of changes in the accessibility of sea ice habitat."
