The White Planet (2006)

"The White Planet" is an extraordinary documentary that examines the impact that global warming is having on the adorable, yet endangered denizens of the North Pole. Featuring astonishing cinematography often at breathtaking proximity, the film makes stars of the local wildlife who prove themselves to be as idiosyncratic, funny and charming as anything that the Ice Age films could come up with - seals with inflatable nostrils, giant walruses with unicorn-like horns (the narwhals) and half a million caribou who make up the world’s second largest yearly migration - but only if the weather report is promising enough.
