Glaciers in Switzerland, known to be the most abundant in the Alps, experienced a 5.5% reduction in ice volume this year, marking the second-largest decline ever recorded. This significant loss was attributed to heat waves and below-average winter snowfall, according to experts.
The GLAMOS Swiss glacier monitoring service and Swiss Academy of Sciences issued a statement on Thursday expressing concerns about the long-term survival of Alpine glaciers under such conditions. The report highlighted a concerning trend, noting that Switzerland’s ice volume has decreased by nearly 20% over the past five years alone.
Experts emphasized the impact of global warming on Europe, labeling it as the continent experiencing the fastest rate of warming globally. Matthias Huss, leading GLAMOS, stated unequivocally that the current warming trend is entirely due to human-induced climate change and the emission of fossil fuels.
In 2022, Switzerland witnessed a record retreat of glacier ice, which was exacerbated by a combination of summer heat, scant winter snowfall, and the deposition of reddish dust from the Sahara. The importance of winter snow cover was underscored by Huss, who explained its role in protecting ice from melting and providing a vital source for glacier nourishment.
The effects of climate change are not limited to Switzerland, as experts pointed to global warming contributing to a Himalayan slope collapse in Nepal and widespread glacier shrinkage in regions like Greenland and Antarctica over the past few decades.
While the absolute volume lost in Switzerland this year is less than in 2003, the percentage decline is more significant due to the substantial reduction in total ice volume over the years. The accelerated ice melt in Switzerland has resulted in the loss of a staggering 2.2 trillion liters of water from July to September, equivalent to four times the country’s annual water consumption.
Notably, glaciers like Allalin, Clarident, Rhone, and Aletsch, the largest in the Alps, experienced unprecedented melting this year. Huss emphasized the urgent need to stabilize the climate by reducing CO2 emissions to mitigate the adverse effects on glaciers, particularly in the Swiss Alps, where the situation is deemed nearly irreversible.
The experts highlighted the critical role of glaciers in the polar regions in regulating sea levels, emphasizing the need for immediate action to limit sea level rise, a threat to billions of coastal inhabitants worldwide.
