Alpine glaciers, goodbye. Their disappearance below 3,500 meters is inexorable by 2050. This is the alarm raised by Legambiente and the Italian Glaciological Committee (CGI). The rise in temperatures of the last 15 years, caused by climate change, leaves no way out for these high-altitude water reserves: within a century, most of them will vanish permanently.
“In the last century – reads the study of Legambiente and the Italian Glaciological Committee (CGI) – Alpine glaciers have lost 50 percent of their area. Of this 50 percent, 70 percent have disappeared in the last 30 years ”.
An example? The Calderone Glacier, the only one in the Apennines, located on the Gran Sasso massif, in Abruzzo, has “now become an authentic ‘black glacier'”, that is “detrital”, notes the meteorological association AQ Caput Frigoris, which on its page Facebook, in a post entitled “Cauldron: a nightmare month”, compares a photo taken on 11 August with one taken on 11 July.
The impressive images allow you to “note a significant and rapid reduction of the already tested surface snow cover “. “To the eloquence of the images – writes AQ Caput Frigoris – we add the measurements made by our weather station at Rifugio Carlo Franchetti (a short distance from the glacier, ndc), 2433 m asl, which record average temperatures of + 12.5 ° C for the month in July and + 13 ° C in the current month of August “. “In addition to the temperatures, the significant action of the wind – concludes the association – should be added, capable of making substantial changes to the pre-existing snow accumulations”.
