- These studies show the unique properties of soils in the permafrost region. To move further, we need to use this knowledge to better project how thawing permafrost will affect future climate, which means focusing on development of new types of models that account for landforms, says Gustaf Hugelius, researcher at the Department of Physical Geography and the Bolin Centre for Climate Research, Stockholm University.
