Analysis: what the polar bears reveal about the climate crisis

Russian environmental authorities have deployed a team of specialists to a remote Arctic region to sedate and remove dozens of hungry polar bears that have besieged the people living there.

The move came after officials in the Novaya Zemlya archipelago, with a population of about 3,000 people, appealed for help.

"There's never been such a mass invasion of polar bears," said Zhigansha Musin, the head of the local administration. "They have literally been chasing people."
