| Summary |
A journey to the polar extremes of our planet. These frozen worlds undergo extreme seasonal transformation, from the total darkness and of the polar winter to summer when the sun never sets. There are incredible shots of humpback whales feeding, with underwater vision revealing how they create a net of bubbles in which to catch their prey. At the end of the Antarctic summer the sea around the continent freezes and the ice expands, doubling the size of Antarctica. While all other life flees north, the emperor penguins are just arriving to breed. When the sun arrives in the Arctic, this frozen ocean encircled by continents begins to change. A male polar bear has spent the winter out on the sea ice, hunting for seals, but now his ice world is literally melting away beneath him; there is vision from the air of the bear swimming more than 100 kilometres in search of ice from which to hunt seals. Finally he arrives at an island where a colony of walruses has landed to breed, but the bear comes off the worst. And, two years on, Planet Earth catches up with the two cubs that were filmed emerging from their den at the start of the series. Independent from their mother, they are now facing incredible survival challenges as climate change transforms the planet's ice worlds |
