Summary:
- Polar bears living in the Canadian Arctic are getting fatter, even as their sea ice habitat is melting due to climate change.
- Researchers found that polar bears in the Western Hudson Bay region have gained significant weight in recent years, likely due to their ability to hunt seals for longer periods as the sea ice forms later in the year.
- However, this short-term gain in weight may not be sustainable in the long run, as the overall decline in sea ice due to global warming could make it harder for polar bears to find and catch their prey, threatening their survival.
