YouTube Description

as posted by the channel

The leader of a team that spent 20 years monitoring hundreds of polar bears in Norway's Svalbard Arctic archipelago tells CBS News he was surprised to see the bears thriving as climate change shrinks the sea ice cover in the region. Tina Kraus looks at the remarkable discovery, what's behind it, and why it doesn't come with any guarantees for the bears' future.
