Air warming trends linked to permafrost warming in the sub-Arctic catchment of Tarfala, Sweden
Recent ground temperature records from the 100-m-deep borehole near the Tarfala Research Station in northern Sweden reveal that permafrost is warming at a pace consistent with the rate of measured air temperature increase at the site. Here we investigate whether air temperature increase is the main...
