Some of the coldest permafrost on Earth might be more vulnerable to thawing than previously thought. In the PERMANOR project led by the University of Oslo, an international research team has investigated so-called thermokarst processes which can significantly accelerate thawing of permafrost.
Det er bred enighet blant klimaforskere om at vintrene i Skandinavia generelt blir varmere og våtere. Dette erfarer vi allerede, og et bredt spekter av klimamodeller viser at denne utviklingen vil fortsette i fremtiden for store deler av Arktis. Men disse modellene viser ikke hva som vil skje på lokalt nivå.
Aerial photos taken by drones are of great help for documenting changes at the ground for researchers at Department of Geosciences. Photos of the thawing of permafrost get attention, and in the May edition of the journal Nature Climate Change is one of their photos of decreasing permafrost in North of Norway chosen as a cover photo.
