They lost 2% of their volume in 2020, reports the Swiss Academy of Sciences.
They have lost 2% of their volume this year. Swiss glaciers have continued to melt at an alarming rate, and snowfall on the largest glacier in the Alps has never been lower, warns a study by l’Swiss Academy of Natural Sciences, published Friday October 16.
These figures correspond to the average observed over the past ten years, but are nonetheless “very disturbing”, explained to AFP the author of the report Matthias Huss, in charge of the Glamos glacier monitoring network. “These numbers are a little lower than the last three years, when we had extremely high temperatures, but still the glaciers lost a lot of mass”, emphasizes the scientist.
Over the past 60 years, Swiss glaciers have lost as much water as there is in Lake Constance, an expanse 63 kilometers long on the Austrian-German-Swiss border, the report insists.
One of the most worrying measures concerns the Aletsch, the largest glacier in the Alps, which stretches over 82 square kilometers. Since the beginning of the 21st century, he has seen his forehead recede a kilometer. And for a little over a hundred years that the measurements are made, “this year marks the lowest snowfall ever” recorded, underlines Matthias Huss.
