Western Hudson Bay polar bear population has fallen 27% in just five years, according to Canada government report, suggesting climate crisis is impacting animals
Polar bears depend on the sea ice to hunt, staking out over seal breathing holes. But the Arctic is now warming about four times faster than the rest of the world.
This has made the population not only the best studied group in the world, but also the most famous, with the local bear-viewing economy valued at $5.30 million annually. Around Hudson Bay, seasonal sea ice is melting out earlier in the spring, and forming later in the fall, forcing bears to go for longer without food.
This change in demographics doesn't fit with the idea that bears are moving out of western Hudson Bay, he added.
