The climate crisis has resulted in a decrease in snowfall throughout Italy, from the Alps to the Apennines. The snowpack is becoming more fragile. The Alps are particularly hard hit, with the length of the snowpack shortening by an average of one month over the previous century due to air warming of around 2 °C. Even the late snowfalls of previous April did not provide the expected effects. Legambiente, based on an examination of numerous scientific and international studies, including one conducted by the CIMA Foundation, asks everyone to think about what is happening at high altitudes as well as in the valley. The environmental association also identifies three priorities for action that require additional attention: the need for more mitigation and adaptation policies and strategies at the national and territorial levels, as well as increased awareness and discussion among Alpine and Apennine resorts regarding the decrease in snowfall and the consequences of the climate crisis. However, it is also imperative for tourists to experience the mountains in winter in a more sustainable manner, rather than chasing for snow. According to the most recent estimations, Italy is one of the Alpine countries that rely the most on artificial snow, with 90% of slopes covered. Investment in a winter mountain tourist offer that emphasizes slow and gentle tourism is essential, as it celebrates the majesty of natural snow in a sober and equally natural manner. More and more research show that there is less and less snow in the Alps. According to a December 2024 study published in the International Journal of Climatology by experts from the University of Trento and Eurac Research in Bolzano, the amount of snow in the Italian Alps has reduced by 50% during the last century. Between 1920 and 2020, snow fell by 34%, with significant disparities in the northern and southwestern Alps: -23% and nearly -50%, respectively. A study published in 2023 in the journal Nature Climate Change (Recent waning snowpack in the Alps is unprecedented in the last six centuries) provides similar confirmations. The study revealed that the snowpack in the central Alps has never been so ephemeral in the last six centuries. Furthermore, atmospheric warming of roughly 2°C has reduced snow duration by an average of one month during the last century.
