Climate change is expected to lead to fewer overall avalanches in Switzerland by 2100, but will increase the incidence of wet snow avalanches significantly. Researchers warn that the safest approach may involve closing ski resorts situated in vulnerable locations.
Recent studies conducted by the WSL Institute for Snow and Avalanche Research (SLF) predict that climate change will significantly alter avalanche behavior in Switzerland by the year 2100. While there will be a general decline in the frequency of avalanches, the risk associated with wet snow avalanches is expected to rise. Specifically, researchers indicate that increased winter temperatures, anticipated to rise by approximately five degrees Celsius, will lead to fewer dry snow avalanches and a higher prevalence of wet snow avalanches.
Climate change poses a significant threat to avalanche dynamics in mountainous regions, especially in the Swiss Alps. As temperatures rise, the overall snowpack will change, leading to fewer dry snow avalanches while increasing the risk of wet snow avalanches—a condition where the snow becomes damp due to rain or melting processes. This shift necessitates reevaluation of safety measures in ski resorts located in avalanche-prone areas.
In summary, climate change is anticipated to bring about a transformative impact on avalanche behavior in Switzerland by 2100. While the frequency of dry snow avalanches is projected to decline, the dangers posed by wet snow avalanches will increase, highlighting the need for proactive measures such as the closure of ski resorts in high-risk areas to mitigate potential hazards for the public.
