"Die Vorstellung eines Klebers, der den Berg zusammenhält, ist für grosse Hanginstabilitäten [...] unpassend", sagt #SLF Forscher Robert Kenner über die gängige Meinung, #Permafrost sei wie ein Kleber.

1/3 The #GLAMOS winter snow accumulation report for Swiss glaciers in 2026 is out! Snow depth measurements on 25 glaciers across Switzerland were carried out in April/May together with colleagues from the Universities of Zurich and Fribourg. #Glaciology #SwissGlaciers
🏔️❄️New book chapter on GLACIAL HAZARDS now published in ‘Comprehensive Cryospheric Science and Environmental Change’.

Der #Klimawandel schreitet voran. In der Schweiz ist es im Jahresmittel bereits rund 3 °C wärmer als in der vorindustriellen Zeit. Eine neue Darstellung zeigt, wann in den verschiedenen Jahreszeiten eine Erwärmung von 1, 2 und 3 °C erreicht wurde. MeteoSchweiz-Blog: https://bit.ly/4tRF7IT
Weathered rock layers beneath the soil influence how groundwater moves during storms. The findings of a new study, led by ETH Zurich researcher Seulgi Moon (formerly UCLA), help explain when and where shallow landslides occur and could improve hazard prediction.
📢 Paper alert!
Anja Rubin et al. used surface exposure dating and runout modelling to elucidate the triggering mechanisms of the Sierre landslide, providing insights into landscape dynamics during the transition to the Holocene.

New preprint from our group! Our PhD student Janosch Beer and several VAW members present a borehole thermometry and radar dataset on englacial temperatures across 6 small Swiss glaciers.
The paper is open for community discussion on EGUsphere!
