Polar Bears Face Increasing Starvation Risk as Sea Ice Melts

A new study using GPS and video collars reveals the dire consequences of climate change on polar bear survival in Hudson Bay.

Polar bears are struggling to adapt to longer ice-free periods, leading to significant weight loss and increased risk of starvation.
Research involving GPS and video collars on 20 polar bears in Hudson Bay reveals their futile efforts to find sufficient food on land.
Alternative food sources on land, such as berries and bird carcasses, do not provide enough energy to offset the bears' weight loss.
The loss of sea ice habitat, crucial for hunting seals, is the primary threat to polar bear survival, with climate change accelerating the trend.
Scientists call for urgent action to mitigate CO2 emissions to preserve polar bear populations and their Arctic habitat.
