Swiss researchers have for the first time quantified the loss of snowfall across the country, revealing an average decline of 8cm per decade over the past 25 years, with some data extending back to 1962. The study, based on measurements from 350 stations, highlights a near-total loss of snow cover in lower areas of the Swiss central plain, while higher mountain regions have maintained similar snow depths.
The findings pose a significant economic threat to ski resorts situated at lower altitudes, which rely heavily on artificial snow. Snow-making machines can account for up to 50% of a resort's energy costs, making them expensive to operate. Swiss ski resorts range from 1,500 metres to the highest ski lift at 3,600 metres, leaving those at lower elevations particularly vulnerable.
The Institute for Snow and Avalanche Research in Davos is sharing the data with the ski industry, including cable car operators, and incorporating it into apps that help tourists predict local skiing conditions. The research underscores the broader impact of the climate crisis on winter tourism in Europe.
