Swiss Alpine ski resorts face 40 drop in snow days

Alpine ski resorts could have 40% fewer snow days per year by the end of the century due to rising global temperatures.

A new study has estimated that from 2071, there would be snow on 137 days a year in the European Alps, 80 fewer than the current average. KEYSTONE/© KEYSTONE / CYRIL ZINGARO

Alpine ski resorts could have 40% fewer snow days per year by the end of the century, with natural snow cover potentially disappearing completely in one in eight resorts worldwide.

That is according to a study published in the scientific journal PLOS ONE. For the study, the research team, led by Veronika Mitterwallner from the University of Bayreuth in Germany, forecasted snow cover in seven major mountain regions worldwide: the Alps in Europe, the Andes, the Appalachian Mountains, the Australian Alps, the Japanese Alps, the Southern Alps in New Zealand and the Rocky Mountains. Gregor Mathes from the University of Zurich was also involved in the study.

“In all major ski regions, a substantial reduction in the number of days with natural snow cover is expected under every emission scenario assessed,” Mitterwallner said in a press release published in the journal.

80 fewer snow days per year

Assuming a strong global warming scenario, no more snow is to be expected in 13% of ski resorts between 2071 and 2100. In 20% of resorts, the number of days with snow cover would be halved.

Ski tourism to move to higher altitudes

Although ski resorts could resort to artificial snowmaking, the economic profitability of many ski resorts worldwide would be negatively impacted, according to the researchers. As a result, a shift of ski tourism to higher altitudes is to be expected – with serious consequences for Alpine flora and fauna.

The findings are in line with the results of previous studies, including one published in the journal Nature Communications in August, which concluded that a third of Swiss ski resorts would be at very high risk of a lack of snow if the climate warmed by 2°C.
