Rising temperatures are melting an area of the Swiss Alps where scientists have been working to collect centuries-old ice cores that contain evidence of past environmental conditions
By analyzing ice collected from glaciers, scientists can study the past composition of the atmosphere and better understand how humans have altered the climate. But the rapid melting of ice may be compromising this critical data, according to a study of the Corbassière glacier in Switzerland.
As part of the Ice Memory initiative, PSI researchers, with colleagues from the University of Fribourg and Ca' Foscari University of Venice as well as the Institute of Polar Sciences of the Italian National Research Council (CNR), analyzed ice cores drilled in 2018 and 2020 from the Corbassière glacier at Grand Combin in the canton of Valais.
Melting of glaciers due to climate change has destroyed climate records. Read more here. Global warming has caused widespread surface lowering of mountain glaciers, revealing that they are no longer appropriate for a climate archive.
The Corbassière glacier at the Grand Combin in canton Valais is melting faster than previously thought, says a study by Swiss and Italian scientists.
