• Winters in Siberian permafrost regions have warmed since millennia

      Press release

    • Reinhard Süring Foundation honours permafrost researcher Moritz Langer

      Award-winning
      AWI permafrost researcher Moritz Langer received the climate award of the Reinhard Süring Foundation. The award is endowed with a prize money of 1500 euro and honours Langer outstanding [...] outstanding study: Satellite-based modeling of permafrost temperatures in a tundra lowland landscape, published in the scientific journal Remote Sensing of Environment.

    • Researchers measure record erosion on Alaskan riverbank

      Permafrost
      According to estimates, Alaska's thawing permafrost soils cost the USA several 100 million dollars every decade – primarily because airports, roads, pipelines and settlements require relocation

    • A glance into the future of the Arctic

      Permafrost
      Throughout the Arctic, ice wedges are thawing at a rapid pace. Changes to these structures, which are very common in permafrost landscapes, have a massive impact on the hydrology of the tundra

    • Siberian larch forests are still linked to the ice age

      Climate and Vegetation
      The Siberian permafrost regions include those areas of the Earth, which heat up very quickly in the course of climate change. Nevertheless, biologists are currently observing

    • AWI's Friends' Association honours permafrost researcher for extraordinary achievements

      Award
      Permafrost researcher Dr Jens Strauss, AWI Potsdam, was awarded "Young Scientist 2015". With this award the chairmen of the Friends' Association acknowledge the researcher's outstanding achievements

    • Great potential for comprehensive monitoring of the water masses in the ocean

      climbing temperatures. In addition, the rivers are carrying large amounts of sediment from thawing permafrost. How the Arctic Ocean will react to such changes is a very big question, which is concerning scientists

    • Retreating permafrost coasts threaten the fragile Arctic environment

      Permafrost
      Permafrost makes up a quarter of the landmass in the Northern Hemisphere. Climate change means that Arctic coasts are thawing and eroding at an ever greater pace, releasing additional greenhouse

    • Beavers are changing the face of the Arctic

      Permafrost
      Beavers are highly effective ecosystem engineers: if a given landscape isn’t quite to their liking, they simply rearrange the terrain. And that’s what they’ve been doing for millennia in [...] to their findings, the animals could change entire ecosystems and contribute to the thawing of permafrost soils, as they report in the journal Global Change Biology.
