Not just the Marmolada, the iconic glacier of the Dolomites—over the coming decades, other glaciers in these mountains could also shrink and eventually disappear. This is stated for the first time in a study conducted by the Institute of Polar Sciences of the National Research Council and Ca' Foscari University of Venice, recently published in the journal The Cryosphere. In 2023, the last year examined in the study, the total number of glaciers was 9, despite the Marmolada glacier being fragmented into four distinct glacial entities, bringing the total to 12. The total area of these last 12 glaciers has decreased from just over 4 square km in the 1980s to just under 2 square km today, a loss of 56%, with 33% of this reduction occurring since 2010. Overall, glaciers' average topographic surface decreased by 28.7 meters between 1980 and 2023, with 33% of that drop occurring between 2010 and 2023. Temperature data are also interesting: an increase of +2.0°C has been documented, with an average of +0.5°C per decade during the last 40 years. At the same time, the statistics show a slight rise in snowfall, but only at high altitudes, a phenomena that, according to the researchers, is insufficient to compensate for the increased melting caused by longer and warmer summers.
