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.
