Italy\u2019s Ventina glacier, one of the biggest in northern Lombardy, has melted so much due to climate change that geologists can no longer measure it the way they have for the past 130 years.<\/p>\n
After this year\u2019s hot summer, geologists discovered that the simple stakes used as benchmarks to measure the glacier\u2019s retreat each year are now buried under rockslides<\/a>. Debris has made the terrain too unsteady for future in-person visits.<\/p>\n The Lombardy Glaciological Service said Monday that it will now use drone imagery and remote sensing to keep track of the ongoing shrinkage.<\/p>\n Geologists say that the Ventina glacier has already lost 1.7 kilometres in length since the first measuring benchmarks were positioned at the front of the glacier in 1895.<\/p>\n The melting has accelerated in recent years, with the glacier losing 431 metres in the last 10 years, nearly half of that since 2021, the service said. It’s another example of how accelerating global warming is melting and shrinking Europe\u2019s glaciers, causing a host of environmental and other impacts.<\/p>\n \u201cWhile we could still hope until the 1980s that there would be normal cycles (of retraction) or at least a contained retraction, in the last 40 years something truly striking has occurred,\u201d said Andrea Toffaletti, a member of the Lombardy Glaciological Service.<\/p>\n Hot summers and less snow are melting Italy’s glaciers<\/p>\n Italy\u2019s mountain glaciers, which are found throughout the Alps and Dolomites in the north and along the central Apennines, have been receding for years, thanks to inadequate snowfall in the winter and record-setting hot summers. <\/p>\n Glaciers always melt some in summer, with the runoff fueling mountain streams and rivers.<\/p>\n But the hot summers are \u201cno longer able to guarantee the survival of the winter snowpack,\u201d which keeps the glacier intact<\/a>, Toffaletti said.<\/p>\n \u201cIn order to regenerate and remain in balance, a certain amount of residual snow from the winter must remain on the glacier’s surface at the end of the summer. And this is happening less and less frequently,\u201d said Toffaletti.<\/p>\n
