The Aletsch glacier. Meanwhile, a jewel of Valais listed as a UNESCO World Heritage Site, valais: aletsch glacier could disappear is rapidly disappeared, according to a recent study by Legambientethe Italian glaciological foundation and Cipra Italia. Considered the largest Alpes Glacier with its 20 km in length. it is back on average 40 meters per year since 2000, according to data from the Swiss Glamos glacier surveillance network.
This white giant could completely disappear by 2100 if the current global warming trends continue. The study reveals that the Alps have warmed 2.9 ° C from the pre -industrial era, twice as much as the world average, according to the Swiss Federal Climate Service.
Risks of collapse
The accelerated melting of the Aletsch glacier is accompanied by worrying geological risks. According to Legambiente, “the melting of glaciers and the instability of the mountains go hand in hand”. The Italian organization notes the presence of “unstable valais: aletsch glacier could disappear moraines. open fractures and active deformations along the slopes overlooking the glacier”, increasing the risk of collapse.
Faced with this alarming situation. Legambiente launched a manifesto calling for the European Union and Switzerland to strengthen their climatic policies. The organization notably requests European surveillance of the cryosphere. transnational governance of glaciers, accompanied by more ambitious adaptation and attenuation policies.
According to the most pessimistic climatic models, only a few glacial caps at the highest altitudes could survive in 2100. Despite the recent snow falls in July. the state of the glacier remains critical, with visible blackening on its sides and a significant loss of thickness, particularly at the level of its terminal language.
