SCNAT Press Release 9. April 2018

For the first time since 2009, the warming trend of alpine permafrost was temporary interrupted in debris slopes and rock glaciers. In these snow-influenced environments, the ground surface was exceptionally cold due to the long-lasting snow cover in spring 2016 and its late arrival in winter 2016/17. The newest results of the Swiss Permafrost Monitoring Network PERMOS show that this marked cooling propagated down to 10m and even 20m at cold sites, e.g. at Stockhorn (3400 m asl) near Zermatt (VS). However, no interruption of the warming trend was observed in steep permafrost terrains, not influenced by snow.
