In today's climate debate, there is only one factor that cannot be calculated in climate models - humans. How can we nevertheless understand our role in the climate system and manage the crisis? Climate change is a complex global problem. Increasingly extreme weather events, rising sea levels, and more difficult living conditions - including for us humans - are already the order of the day. Global society has never faced such a complex challenge. For young people in particular, the frightening climate scenarios will be a reality in the future. For the global south, it is already today. To overcome this crisis, different perspectives are needed. "THE UNPREDICTABLE FACTOR" goes back to the origins of the German environmental movement, accompanies today's activists in the Rhineland in their fight against the coal industry and gives a voice to scientists from climate research, ethnology and psychology.

Taleb, who came to a refugee camp at the age of five in 1975 and returned there after his studies abroad, tells of his life as a displaced person, his gratitude for the reception and support in Algeria, and his hope that the Sahrawis may one day return to their homeland.

Thule, Greenland, also called Qaanaaqis, one of the northernmost towns in the world. As the climate warms and the ice caps begin to melt, the gentle balance of life for the people of this community is in jeopardy. On the other side of the globe, the melting ice caps are raising sea levels around the Polynesian island nation of Tuvalu, threatening to wipe the island right off the map. Though a world apart, these two communities are intricately connected as environmental balance begins to tip and traditional ways of life are threatened. 'ThuleTuvalu' is a stunning documentary addressing the high price of a hundred years of development and how two very different communities are now bound together in facing an uncertain future.
