The beauty of the Arctic is breathtaking. For as long as we can remember, the Arctic has been associated with inhospitable cold. But the climate is changing, and with it the northern polar region, which begins beyond latitude 66.5 degrees north. Climate change is now happening four times faster north of the Arctic Circle than on the rest of the planet, making the future outlook dire. At the moment it is still possible for polar bears to raise their cubs, but hunting is becoming increasingly difficult on the drastically shrinking pack ice. The disappearance of the ice also affects the marine fauna. The wintry ice bridge between Canada and Greenland is threatened with collapse. The unstoppable melting of the permafrost, which has held the tundra together for thousands of years, is worrying. But the Arctic is still one of the wildest and loveliest regions on earth. A documentary visit to the Arctic - as long as it still exists.
