SCNAT Press Release 6. February 2017

Since the beginning of the PERMOS borehole monitoring activities 15 to almost 30 years ago, permafrost temperatures were never as warm as in 2016. This warming trend was particularly important at several 10 m depth and most pronounced at cold sites, e.g. at Stockhorn (3400 m asl) near Zermatt (VS). This is shown by the newest results of the Swiss Permafrost Monitoring Network PERMOS. The exceptionally high permafrost temperatures are a result of the continuously warm conditions at the ground surface over the past years and decades. The alpine permafrost is in a strong disequilibrium with the climatic conditions.
