The iconic glacier in Italy’s northern Gran Paradiso Park is at risk of disappearing by 2040 amid the climate crisis, the Italian Meteorological Society said Thursday.

“At the current rate of mass loss, it is likely that the Ciardoney glacier will not survive until 2040,” was the conclusion reached by the Italian Meteorological Society in a report following end-of-summer measurements taken on September 21 at the Ciardoney glacier in the Soana Valley, on the Piedmont side of the Gran Paradiso National Park.

The data were collected in collaboration with Iren Energia, Gran Paradiso National Park, the University of Turin, Sapienza University of Rome, Arpa Piemonte, and the Altra Quota association, as part of observation campaigns led by the Italian Glaciological Committee Foundation.

“A lack of spring snow and, above all, the extreme and prolonged summer heat have caused massive losses of glacial mass,” the report—released via social media—continued.

“Over three years, 2.2 million cubic meters of ice have been lost, representing a volume of water runoff sufficient to fill, on average, about 250 Olympic-sized swimming pools per year.”
