Glaciers in Switzerland, known for housing the most glaciers in the Alps, experienced a 5.5% reduction in ice volume this year, marking the second-largest decline on record. This significant loss was attributed to heat waves and low snowfall during winter, as reported by experts.
According to the GLAMOS Swiss glacier monitoring service and Swiss Academy of Sciences, the long-term survival of Alpine glaciers is doubtful under these conditions. The trend has intensified in recent years, with a nearly 20% decrease in ice volume in Switzerland over the past five years.
The findings underscore growing concerns about the detrimental effects of global warming on Europe, the continent experiencing the most rapid temperature rise worldwide. Matthias Huss, the head of GLAMOS, emphasized that the current warming is entirely due to human-induced climate change, stating that without emissions from fossil fuels, such warming would not occur.
In 2022, Switzerland witnessed a record retreat of glacier ice, mainly due to a combination of summer heat, reduced winter snowfall, and the deposition of reddish dust from the Sahara. Huss highlighted the importance of winter snow cover in protecting glaciers from melting and facilitating the formation of new ice.
The impact of accelerated glacier melting extends beyond Switzerland, affecting regions like the Himalayas, Greenland, and Antarctica. The loss of 2.2 trillion liters of water from Swiss glaciers between July and September is four times the country’s annual water consumption. Switzerland, a key water source for Europe, supplies vital rivers such as the Danube, Po, Rhine, and Rhone.
Notable glaciers like Allalin, Clarident, Rhone, and Aletsch, the largest in the Alps, experienced unprecedented melting this year. Experts have conducted assessments to analyze the runoff and crevices resulting from the flowing water, using red dye to trace water movements.
Huss emphasized the urgent need to stabilize the climate by reducing CO2 emissions to safeguard glaciers, particularly in the Swiss Alps. He highlighted that immediate action is crucial to protect polar ice sheets and mitigate rising sea levels, which pose a significant threat to coastal populations worldwide.
