Our Frozen Planet: Our frozen planet is changing. In this final episode, we meet the scientists and people dedicating their lives to understanding what these changes mean, not just for the animals and people who live there, but for the world as a whole. Our journey begins in the Arctic, where every summer huge quantities of ice calve from the edges of Greenland’s melting glaciers. On top of the ice cap itself, glaciologist Alun Hubbard descends into a moulin to try to understand the mechanisms that are driving this historic loss of ice.       Elsewhere in the Arctic,

Frozen Lands: In the far north of our planet lies the largest land habitat on earth, home to snow-covered forests and the icy open tundra. These are lands of extremes that push animals to their limits: in winter they are so cold that much of the ground has remained frozen since the last ice age. To stand any chance of survival, animals must adapt in extreme ways: here a super pack of wolves, 25 strong, has come together to take on the only large prey available to them in winter, American bison.       On the featureless tundra, an

Frozen South: Antarctica is the most hostile of all earth’s frozen worlds. Yet even here, amongst some of the most challenging conditions on the planet, life finds a way not just to survive, but thrive. Our journey begins at the far edge of the continent, on its far-flung sub-Antarctic islands. Here we meet king penguins that, to feed at sea, must face the danger of ferocious leopard seals lurking in the shallows. On another island, we witness for the first time male Antipodean wandering albatross partnering up with each other as the females in their population are disappearing due to

Frozen Peaks: Mountains create frozen habitats on every continent on Earth, and each of these high-altitude worlds holds unique challenges for its surprising and remarkable life. We begin our journey close to the equator – the furthest point from the poles – in East Africa. Here on the high slopes of Mount Kenya, during the day the tropical sun keeps the cold at bay, but at night the frost descends. During this cycle of freeze and thaw, a pregnant high-casqued chameleon must choose the right time to give birth if her newborns are to escape the deadly night freeze.  

Frozen Ocean: At the top of our planet lies a magical realm, the Arctic Ocean. After four months of winter darkness, the sun returns to reveal a frozen ocean covered in ice. Mother polar bears emerge from their hillside dens and lead their cubs down to the sea ice to hunt, while a young male and female bear forge a surprising friendship out on the ice.       For others, the frozen sea is a trap. A pod of beluga whales has been confined to an ice hole for five months, slowly starving to death as the food around

Frozen Worlds: Journeying from pole to pole, we reveal the surprising frozen worlds that exist across the planet and the remarkable animals that make them their home. We begin our journey in the far south, in the most hostile place on earth, the frozen continent of Antarctica. After being raised on the ice in winter, emperor penguin chicks find themselves abandoned by their parents in spring. To survive, they must find their own way across the treacherous sea ice to the rich waters of the Southern Ocean.       The waters surrounding Antarctica may be the richest of all,
