The measures introduced after the avalanche winter of 1999 have proved their worth. This is shown by the event analysis of January 2018.


Exceptional snowfall in the north and short-term 'very high' avalanche danger.


The SwissForestLab/NFZ Summer School "Forest Resilience" for doctoral students will take place in Davos from 18 to 24 August. Apply until 6 May!


On May 24 2019 a WSL symposium on 'Learning from extreme events' for scientists and practitioners will take place in Davos (in German).


The PROSNOW project aims to provide meteorological and climatological forecasts to optimise snow management in ski resorts.


Under a limited warming scenario, glaciers would keep about one-third of their volume. Under strong warming, the Alps would be ice free by 2100.


SLF measurements reveal that a quarter of a million cubic metres of rock collapsed at Flüela Wisshorn shortly after midnight on March 19 2019.


The multi- and interdisciplinary WSL investigates complex topics such as avalanche danger or drought. For more information see the Annual Report 2018.


SLF is investigating which properties of a forest determine the level of protection it provides and how this could be altered by climate change.


New data reveal that temperatures in the upper layers of the permafrost have reached record values after a period of cooling (German or French).


Floods, landslides and debris flows caused some CHF 200 million of damage in Switzerland in 2018.


The ETH Board appointed landscape researcher Anna M. Hersperger as a member of the WSL-Directorate.


SLF collects and archives interesting facts on avalanche accidents. There is now an overview of all accidents known to SLF during the current year.


How does climate change affect winter sports? More than 20 scientists point out the spots where our knowledge is lacking, and where we need to act.


A new method that automatically computes avalanche starting zones facilitates the simulation of avalanches on a large scale.


Three experts will present the current scientific knowledge on global climate change and discuss future impacts on mountain sports.


The winter of 1998/99 claimed many lives and caused extensive damage to property in the Alps. What lessons have been learned from this experience?


How does a gliding avalanche form? What should snow sports enthusiasts consider in the terrain?


A new estimate for the glacier ice volume all around the world indicates the volume of glaciers in Asia has been overestimated.
