Polar bears risk starvation as they face longer ice-free periods in the Arctic

Bears use ice to access food, but study of animals in Canada shows them struggling to adapt to more time on land amid climate crisis

Polar bears use the ice that stretches across the ocean surface in the Arctic during colder months to help them access their main source of prey - fatty ringed and bearded seals.
