National Geographic: Emperors of the Ice
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.
