Polar bears dying at a rapid rate near Canada's "Polar Bear Capital" as Arctic sea ice disappears

Polar bears in Canada's Western Hudson Bay — on the southern edge of the Arctic — are continuing to die in high numbers, a new government survey of the land carnivore has found. Females and bear cubs are having an especially hard time.

Researchers surveyed Western Hudson Bay — home to Churchill, the town called "the Polar Bear Capital of the World" — by air in 2021 and estimated there were 618 bears, compared to the 842 in 2016, when they were last surveyed.

"The actual decline is a lot larger than I would have expected," said Andrew Derocher, a biology professor at the University of Alberta who has studied Hudson Bay polar bears for nearly four decades. Derocher was not involved in the study.
