In the first episode of Greenland: Survival At The Edge Of The World, we trek onto the second largest ice sheet in the world, one of the best places to see the impacts of a warming climate. By air we see the stunning ice fjords fed by the majestic glacier behind it. In the fishing town of Ilulissat we sample the local cuisine and ancient crafts, then onto the beautiful lake of Tasersuatsiaq, home to the giant muskox, a specialised survivor from the Ice Age.

In this episode, we take to the ice on dog sled to see how the Inuit hunt in this extreme environment. Onboard The Kisaq, we head through rough weather and pass huge colonies of seabirds – guillemots and kittiwakes and giant icebergs, where we see first-hand the effect of climate change as they crumble into the ocean. Small fishing villages dot the coastline where local fishermen use traditional methods unchanged for centuries.
