  • “Snowball Earth” mystery solved

    The deep freeze of the Earth some 650 million years ago was not total.
  • Blue mussels à la Svalbard on the menu?

    Back when the Vikings ruled, blue mussels had a natural habitat in Svalbard. They disappeared when the climate cooled, but today blue mussels have re-established themselves at 78 degrees North. The Svalbard blue mussel is thus a clear and present climate indicator of a warming Arctic.
  • Arctic species will survive less ice

    Some of the species in the Arctic have adapted to minimal ice cover in summer. The scientists call their hypothesis the “Nemo hypothesis”.
  • Mice on ice

    Never heard of glacier mice? Actually, they are small moss balls forming on glacier surfaces. New research shows that there is lots of life in these fluffy balls.
  • Tourists bring alien seeds

    Tourists can unwittingly bring alien plant species to Svalbard. Increased travel activity and expected temperature increases might alter the island's ecosystem.
  • Arctic plants face an uncertain future

    A warmer climate will cause a substantial loss of habitat for most Arctic plants. Some species will cope, while others will experience an irrevocable loss of genetic diversity.
