"In the frozen wilderness of Antarctica, where oceans ice over and just staying alive is an acheivement, one creature has prefected 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 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."
