- Polar bears in Canada's Hudson Bay are at risk of starvation due to climate change, which is lengthening periods without Arctic Sea ice.
- Despite their efforts to find food on land, extended ice-free periods are causing the bears to lose weight and increasing their risk of starvation.
- To ensure the long-term survival of polar bear populations, it is crucial to reduce greenhouse gas emissions and limit global warming.

Polar bears living in Canada's Hudson Bay face extinction due to hunger. Although these animals have already expanded their diet, climate change makes their survival impossible as periods without ice in the Arctic Ocean are getting longer.
Polar bears are unlikely to withstand ever longer Arctic summers. These periods force them to spend more time on dry land, where they are unlikely to be able to adapt to those conditions and will even risk dying of starvation, according to a new study published in Nature Communications.

A study by the U.S. Institute of Geological Studies indicates that polar bears face an increased risk of starvation because they spend more time on land. Since the early 1980s, the duration of ice in western Hudson Bay has been reduced by three weeks.
Researchers at USGS and Washington State University who placed cameras on 20 bears for three summers.
The new Arctic: Amid record heat, ecosystems morph and wildlife struggle
Walruses have traversed the Arctic for millennia, gregarious pinnipeds that rest en masse on drifting pack ice, diving to feed on crabs, clams and other seafloor delicacies. Icy platforms also serve as safe birthing and nursery grounds. But as the far north rapidly warms and sea ice disappears, some herds now huddle on overcrowded shorelines, with deadly consequences for young calves: Because more disturbances occur on shore than at sea, calves …
Polar bears face starvation risk in longer ice-free Arctic periods, scientists warn
Polar bears are at risk of starvation in longer ice-free seasons in the Arctic, despite their ability to adapt their diet and behaviour, scientists have warned. Climate change is increasing the time some areas of the Arctic are ice-free each year, forcing polar bears– which are specialised to use the ice to hunt their preferred food of seals – to spend longer on land in those regions. Polar bears monitored by scientists in a new study led by re…
