Four Swiss university students covered an Alpine glacier with sheep's wool and managed to reduce its melting by more than 50% in just three months

Four students from the University of Lausanne (UNIL) in Switzerland successfully reduced the melting of an Alpine glacier by more than 50% over a three-month period. The initiative involved covering 200 square meters of the Tsanfleuron glacier in the Swiss Alps using blankets made of sheep's wool.

The project demonstrates a targeted, physical intervention to combat glacial melt at a localized scale. By utilizing sheep's wool to insulate a section of the ice, the university researchers achieved a significant reduction in ice loss during the three-month observation window.
