National Geographic: Emperors of the Ice
7.00 52 minutes 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? Using Crittercam, scientists take a virtual ride under the ice with the emperor penguin to study the impact of climate change on the penguin's world.
