Will polar bears make it back to shore?

The future looks bleak for this polar bear and her cub huddled on a rapidly shrinking iceberg 12 miles out to sea.

The pair became stranded after climbing onto the chunk of ice during a expedition to hunt seals. Soon the ice floe shrank down to just a few yards and rapidly drifted down the Olga Strait of Svalbard in Norway.

But although the bears look frightened, huddled together in the centre of the iceberg, experts predicted that the agile swimmers will be able to get safely back to shore.


Images of polar bears stranded out at sea are often used to highlight the affect of global warming on the North Pole.

Sea ice has retreated dramatically in the past decade and some scientists predict that the Arctic could be largely ice free during the summer in the next 20 years.

Eric Lefranc, 40, who took the photograph while cruising in the area, doubted the cub would survive.

"If she was able to leave her baby, the mother would probably have survived but our guide was quite pessimistic about the survival of the cub, who probably drowned," he said.

"Some of the members on our trip were in despair. They wanted to take the bears with us and bring them to the nearest land which was obviously impossible."

However Chris Packham, the BBC presenter of Springwatch and animal expert, said polar bears have adapted to such conditions.

"Being so isolated, their fate may look doomed but I think there will have been a happy ending," he said.

"Polar Bears have four-inch thick blubber to keep them warm, big paws that act as flippers and waterproof fur – that means they are incredibly well suited to the water.

"An adult can swim up to 50 miles at five or six miles per hour so the mum here should have no trouble completing the 12 miles back.

"The cub will struggle more and certainly faces an exhausting swim but I imagine it will have been OK if they paced the journey."
