The Yamal Peninsula: a stretch of peatland that extends from northern Siberia into the Kara Sea, far above the Arctic Circle. To the east lie the shallow waters of the Gulf of Ob; to the west, the Baydaratskaya Bay, which is ice-covered for most of the year. Yamal in the language of the indigenous Nenets means "the end of the world." It is a remote, wind-blasted place of permafrost, serpentine rivers and dwarf shrubs, and has been home to the reindeer-herding Nenets people for over a thousand years. Today, the Nenets' nomadic way of life is under threat from the effects of climate change, making the tundra increasingly unpredictable, and from the discovery that the peninsula contains the largest gas reserves on the planet.
