Climate change has reached the indigenous Nenets people in the north of Siberia. The nomads' herds of reindeer move on thin ice. The warming in the Russian Arctic is becoming dramatically visible. Huge craters open in the thawing permafrost and expose dangerous viruses and bacteria. Forest floors dry out and the taiga catches on fire. The pack ice off the coast is melting and depriving polar bears of their habitat so that they approach human settlements in their desperation. The changes in the nature of the Arctic Circle combine with the measurements of researchers and observations of the indigenous people to form a disturbing overall picture: In the Russian Arctic, Pandora's box has been opened!
