Majestic, increasingly hungry and at risk of disappearing, the polar bear is dependent on something melting away on our warming planet: sea ice.

It turns out that a bit of melting helps support larger populations of seals, which are the bears’ main food supply. But this benefit will likely dwindle as sea ice continues to melt due to climate change, said Brandon Laforest, senior specialist of Arctic species and ecosystems with WWF-Canada.

Nearly 60 polar bears have been stranded on the Arctic coast near a remote village in Russia's Far East after warm winter weather hampered their hunting routine.

More polar bears on land have been encountering more people in the Arctic, a perfect storm of dangerous conditions, one scientist says.

The habitat overlap of polar bears and their main prey, ringed seals, is disappearing and the bears are instead getting closer to nesting birds.

A recent study shows that polar bears' mercury levels are declining as melting ice drives them onshore. But is it all good news? Read on.

Seven polar bears, including a wounded mother bear with two cubs, were scared away by rescuers after they got dangerously close to reindeer herders at several locations on the Yamal peninsula. There are concern over rising numbers of the Arctic’s largest predators leaving their natural habitat and coming closer to humans.
