A new study finds that polar bears in Svalbard are beginning to leave their dens with cubs one week earlier than before 2016, a trend that may be linked to climate change and the resulting loss of sea ice.

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

Shorter periods of sea ice on Hudson Bay as a result of climate change translate into fewer polar bears in Churchill region.

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