SCNAT Press Release 08. April 2021

The warming trend of the last two decades in permafrost in the Swiss Alps continues and intensifies during the hydrological year 2019/2020. This is shown by more than 20 years of measurements within the framework of the Swiss permafrost monitoring network PERMOS: permafrost temperatures have reached record levels in many places, as have the thickness of the active layer (the uppermost layer of the ground that thaws in summer) and the rock glacier velocity.
