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 tried different strategies to maintain energy reserves on land, including resting, scavenging and foraging, but almost all lost weight rapidly.

Polar bears face starvation risk in longer ice-free Arctic periods, scientists warn

In a new study tracking the lives of polar bears near Churchill, Man., researchers aimed to find out what they live on during the summer. Some conserved energy while others scrambled for food, but nearly all lost weight — raising concerns about starvation risks in the future as sea ice declines.

Climate change and loss of sea ice putting polar bears at risk of starvation, collar cameras show

By SETH BORENSTEIN
AP Science Writer With Arctic sea ice shrinking from climate change, many polar bears have to shift their diets to land during parts of the summer. A new study looking at Hudson Bay polar bears tries to figure out if they can keep up their roly-poly figure, which is what’s needed. Tuesday’s research found that an overwhelming number of them are dropping the pounds no matter what they do to try to beef up their weight. They may…
