SNIP: A boatload of tourists in the far eastern Russian Arctic thought they were seeing clumps of ice on the shore, before the jaw-dropping realisation that about 200 polar bears were roaming on the mountain slope.

The bears had come to feast on the carcass of a bowhead whale that washed ashore, later resting around the food source. The crowd included many families, including two mothers trailed by a rare four cubs each, Gruzdev told AFP.

Climate change means ice, where polar bears are most at home, is melting earlier in the year and so polar bears have to spend longer on land, scientists say.

Studies have shown that, compared with 20 years ago, polar bears now spend on average a month longer on Wrangel Island because “ice is melting earlier and the ice-free period is longer”, said Eric Regehr, from the University of Washington, the lead American scientist on the US-Russian collaborative study of Wrangel Island polar bears.

Changing ice conditions could also be responsible for the increasing number of bears flocking there, Regehr said.

This autumn, the number of bears observed was 589, far exceeding previous estimates of 200-300, he said, calling it “anomalously high“.
