Den frosne planet

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 frozen continent of Antarctica.

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. However, with climate change, it is warming faster than anywhere else on Earth.

Mountains create frozen habitats on every continent on Earth, and each of these high-altitude worlds holds unique challenges for its remarkable life. Today, due to climate change, our frozen peaks are undergoing rapid change.

Antarctica is the most hostile of all Earth's frozen worlds. Yet even here, 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.

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.

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.
