In a transnational study, data regarding the Alpine-wide snow depth from 1971 to 2019 was now assembled and analyzed. A decreasing snow level in the winter (from December to Februar) was recorded at 82 percent of all monitoring stations, in spring (March to May) even at 90 percent of the monitoring stations. Depending on the altitude, the number of days with snow is reduced by 22 to 27 days in the northern Alps and by 24 to 34 days in the Southern Alpine region. The trends are clear, even if the correlation with climate change is not explicitly discussed in this publication of The Cryosphere.
