The Arctic and Antarctic experience the most extreme seasons on Earth. Time-lapse cameras watch a colony of emperor penguins, transforming them into a single organism. The film reveals new science about the dynamics of emperor penguin behaviour.
In the north, unique aerial images show a polar bear swimming more than 100km. Diving for up to two minutes at a time.
