Swiss Glaciers Have Melted By A Terrifying Rate In Last 2 Years, Study Finds

GENEVA (AP) — A Swiss Academy of Sciences panel is reporting a dramatic acceleration of glacier soften within the Alpine nation, which has misplaced 10% of its ice quantity in simply two years after high summer season warmth and low snow volumes in winter.
Switzerland — house to essentially the most glaciers of any nation in Europe — has seen 4% of its complete glacier quantity disappear in 2023, the second-biggest decline in a single yr on prime of a 6% drop in 2022, the most important thaw since measurements started, the academy’s fee for cryosphere remark mentioned.
Experts on the GLAMOS glacier monitoring center have been on the lookout for a doable excessive soften this yr amid early warning indicators in regards to the nation’s estimated 1,400 glaciers, a quantity that’s now dwindling.
“The acceleration is dramatic, with as much ice being lost in only two years as was the case between 1960 and 1990,” the academy mentioned. “The two extreme consecutive years have led to glacier tongues collapsing and the disappearance of many smaller glaciers.”
Matthias Huss, head of GLAMOS, which participated within the analysis, mentioned in an interview that Switzerland has already misplaced as much as 1,000 small glaciers, and that “now we are starting to lose also bigger and more important glaciers.”
“Glaciers are the ambassadors of climate change. They make it very clear what is happening out there because they respond in a very sensitive way to warming temperatures,” he mentioned. “The study underlines once again that there is big urgency to act now if you want to stabilize (the) climate, and if you want to save at least some of the glaciers.”
The staff mentioned the “massive ice loss” stemmed from a winter with very low volumes of snow — which falls on prime of glaciers and protects them from publicity to direct daylight — and high summer season temperatures.
All of Switzerland — the place the Alps reduce a swath by way of a lot of the southern and central components of the nation — was affected, and glaciers within the southern and jap areas melted nearly as quick as in 2022′s document thaw.
“Melting of several meters was measured in southern Valais (region) and the Engadin valley at a level above 3,200 meters (10,500 feet), an altitude at which glaciers had until recently preserved their equilibrium,” the staff mentioned.
The common loss of ice thickness was as much as 3 meters (10 toes) in locations such because the Gries Glacier in Valais, the Basòdino Glacier within the southern canton, or area, of Ticino, and the Vadret Pers glacier system in jap Graubuenden.
The scenario in some components of the central Bernese Oberland and the Valais was much less dramatic — comparable to for the Aletsch Glacier in Valais and Plaine Morte Glacier within the canton of Bern, as a result of they enjoyed extra winter snowfall. But even in such areas, “a loss of over 2 meters of the average ice thickness is extremely high,” the staff mentioned.
Snow depths measured within the first half of February have been typically larger than within the winters of 1964, 1990 or 2007, which have been additionally characterised by low snowfalls, the staff mentioned. But snow ranges sank to a brand new document low within the second half of the month of February, reaching solely about 30% of the long-term common.
Over half of automated monitoring stations above 2,000 meters which were in place for not less than a quarter-century tallied record-low ranges of snow on the time.
After that, a particularly heat June precipitated snow to soften two to 4 weeks sooner than normal, and mid-summer snowfalls melted in a short time, the staff mentioned.
Swiss meteorologists reported in August that the zero-degree Celsius level — the altitude the place water freezes — had risen to its highest stage ever recorded, at practically 5,300 meters (17,400 toes), which implies that all of the Swiss Alpine peaks confronted temperatures above freezing.
