    like what we now see in eastern Siberia. Today’s Arctic, with ice-covered Greenland, Siberian permafrost and sea ice at the North Pole, is a holdover of that glacial world. But for how much longer? As

  • Arctic coasts in transition

    Permafrost
    Arctic coasts are characterized by sea ice, permafrost and ground ice. This makes them particularly vulnerable to the effects of climate change, which is already accelerating rapid coastal

  • Thawing Permafrost is Shaping the Global Climate

    Permafrost
    How is climate change affecting the permanently frozen soils of the Arctic? What will the consequences be for the global climate, human beings, and ecosystems? And what can be done to stop [...] an AWI group led by Moritz Langer has now created an interactive map of the past and future of permafrost. Both publications arrive at the same conclusion: to put a stop to the dangerous trends in these

  • Permafrost contains more nitrogen than previously assumed

    New Study
    As a result of global warming, permafrost regions around the world are thawing now. As they do, climate-relevant greenhouse gases containing carbon (carbon dioxide, methane) and nitrogen (nitrous [...] climate forecasts. Whereas substantial research has been conducted on the carbon reservoirs in permafrost, we still know comparatively little about nitrogen. A team of experts led by the Alfred Wegener

  • Future emissions from ‘country of permafrost’

    By the end of this century, permafrost in the rapidly warming Arctic will likely emit as much carbon dioxide and methane into the atmosphere as a large industrial nation, and potentially more than the U.S. has emitted since the start of the industrial revolution. More information on the findings of an international team inculding scientists from the Alfred Wegener Institute can be found in this press release by the Northern Arizona University...
