Rome (AP) – The largest Italian benchina glacier in northern Lombardy has It melted very much Climate change has made geologists unable to measure as they did in the last 130 years.
After this year Hot summerGeologists have discovered that simple stakes, which are used as benchmarks to measure glacial withdrawals each year, are buried under rocks and debris that have made the topography too unstable for future in-person visits.
Lombardy Glaciological Service said Monday it will use drone imaging and remote sensing to track ongoing contractions.
Geologists say that the Benchna Glacier has already lost 1.7 km (1 mile) as the first measurement benchmark was placed in the front of the glacier in 1895.
Melting has accelerated in recent years, with the glacier losing 431 meters (471 yards) over the past decade, losing almost half of that since 2021. This is another example of how to accelerate global warming It has melted and reduced European glaciers, causing many environmental and other effects.
“We could still hope for a normal cycle (of retraction) or at least a containment withdrawal until the 1980s, but something really impressive has happened over the last 40 years,” said Andrea Tofaretti, a member of the Lombardi Glacier Service.
The whole of the northern Alps and dolomite, and the mountain glaciers of Italy along the central Apennines I’ll retreat for yearsthanks to insufficient snowfall and record-breaking hot summers in winter. Glaciers always melt some in the summer, and runoff burns creeks and rivers in the mountains.
But the hot summers “can no longer guarantee that winter snow will survive,” Tofaretti said, leaving the glacier intact.
“A certain amount of residual snow from winter needs to remain on the surface of the glaciers at the end of summer to regenerate and maintain balance. This is happening more and more frequently,” Tofaretti said.
According to the Lombardy Service, the Alps represent a climate hotspot, doubles the global average of temperature rises since before the Industrial Revolution, resulting in losses of more than 64% of the volume of Alpine glaciers.
In February, Nature reported a natural journal on a study showing that it lost ice at a rate of approximately 255 billion tons (23.1 billion tons) per year between 2000 and 2011, but it went faster to approximately 346 billion tons (314 billion tons) per year in the following December.
