In the frozen wilderness of Antarctica, where oceans ice over and just staying alive is an achievement, one creature has perfected the art of survival - the emperor penguin. Emperor penguins are sublimely built to conquer the cold - but in a world threatened by climate change, can they take the heat? Parts of Antarctica are warming, giving birth to huge icebergs, and the consequences could be catastrophic in a place where all life is touched by the ice. Using Crittercam, scientists hitch a virtual ride under the ice with the emperor penguin to study the impact of climate change on the penguin's world. Approximately 52 minutes long.
