Frozen Planet

From the Poles to the highest mountain peaks, there are surprising frozen worlds found on every continent – home to unique and remarkable animals.

This edition looks at the Arctic Ocean, as after 4 months of winter darkness the sun returns. Mother polar bears emerge from their dens, a pod of beluga whales confined to an ice hole wait for release, harp seal mothers teach their pups.

Explore ice worlds born of altitude. Found on every continent, these icy ‘islands in the sky’ pose a range of challenges for the animals who choose to live there.
