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.
