Wissenschaftler warnen vor Viren aus dem Eis

  • An aerial view shows thermokarst lakes outside the town of Chersky in northeast Siberia August 28, 2007. For millennia, layers of animal waste and other organic matter left behind by the creatures that used to roam the Arctic tundra have been sealed inside the frozen permafrost. Now climate change is thawing the permafrost and lifting this prehistoric ooze from suspended animation. Zimov, a scientist who for almost 30 years has studied climate change in Russia's Arctic, believes that as this organic matter becomes exposed to the air it will accelerate global warming faster than even some of the most pessimistic forecasts.

  • Scientists said on October 20 that they had dug up an entire 23,000-year old woolly mammoth, with the tusks shown here being loaded at the Jarkov site in this undated photo, from the Siberian permafrost and transported it intact and still frozen. Radar imaging techniques were used to "see" the creature in its icy grave, and is the first time a mammoth carcass from the Siberian permafrost has been excavated under such cold conditions, according to Dick Mol of the Museum of Natural History in Rotterdam.
