bears can give birth to cubs on sea ice, increasing numbers
of female
bears now come ashore in Alaska in the summer and fall40 and den on land.41 In Hudson Bay, Canada, the
most studied population in the Arctic, sea ice is now absent for three weeks longer than just a few decades ago, resulting in less body fat, reduced survival

bears, 42 and a population now estimated to be in decline43 and projected to be in jeopardy.44 Similar
polar bear population declines are projected for the Beaufort Sea region.45
