MORTERATSCH GLACIER, Switzerland \u2014 From the way 45-year-old Swiss glaciologist Andreas Linsbauer bounds over icy crevasses, you would never guess he was carrying 10 kg of steel equipment needed to chart the decline of Switzerland\u2019s glaciers.<\/p>\n
Normally, he heads down this path on the massive Morteratsch Glacier in late September, the end of the summer melt season in the Alps. But exceptionally high ice loss this year has brought him to this 15-square-kilometer (5.8-square-mile) amphitheatre of ice two months early for emergency maintenance work.<\/p>\n
The measuring poles he uses to track changes in the depth of the pack are at risk of dislodging entirely as the ice melts away and he needs to drill new holes. <\/p>\n
The Alps\u2019 glaciers are on track for their highest mass losses in at least 60 years of record keeping, data shared exclusively with Reuters shows. By looking at the difference in how much snow fell in winter, and how much ice melts in the summer, scientists can measure how much a glacier has shrunk in any given year.<\/p>\n Since last winter, which brought relatively little snowfall, the Alps have sweltered through two big early summer heatwaves \u2014 including one in July marked by temperatures near 30 Celsius (86 Fahrenheit) in the Swiss mountain village of Zermatt.<\/p>\n During this heatwave, the elevation at which water froze was measured at a record high of 5,184 meters (17,000 feet) \u2014 at an altitude higher than Mont Blanc\u2019s — compared with the normal summer level of between 3,000-3,500 meters (9,800-11,500 feet).<\/p>\n \u201cIt\u2019s really obvious that this is an extreme season,\u201d Linsbauer said, shouting over the roar of rushing meltwater as he checked the height of a pole jutting out of the ice.<\/p>\n Most of the world\u2019s mountain glaciers \u2014 remnants of the last ice age \u2014 are retreating due to climate change. But those in the European Alps are especially vulnerable because they are smaller with relatively little ice cover. Meanwhile, temperatures in the Alps are warming at around 0.3C per decade \u2014 around twice as fast as the global average.<\/p>\n If greenhouse gas emissions continue to rise, the Alps glaciers are expected to lose more than 80% of their current mass by 2100. Many will disappear regardless of whatever emissions action is taken now, thanks to global warming baked in by past emissions, according to a\u00a02019 report<\/a>\u00a0by the U.N. Intergovernmental Panel on Climate Change.<\/p>\n Already, Morteratsch is much changed from the glacier depicted on the region\u2019s tourist maps. The long tongue that once reached deep into the valley below has shrunk back by nearly 3 kilometers (2 miles), while the depth of the snow and ice pack has thinned by up to 200 meters (656 feet). A parallel glacier Pers flowed into it until 2017 but has now receded so much that an expanding strip of grit lies between them.<\/p>\n The dire situation this year raises concern that the Alps\u2019 glaciers might vanish sooner than expected. With more years like 2022, that could happen, said Matthias Huss, who leads Glacier Monitoring Switzerland (GLAMOS<\/a>).<\/p>\n \u201cWe are seeing model results expected a few decades in the future are happening now,\u201d Huss said. \u201cI did not expect to see such an extreme year so early in the century.\u201d<\/p>\n Reuters spoke with glaciologists in Austria, France, and Italy who confirmed that glaciers there were on track for record losses. In Austria, \u201cthe glaciers are snow-free up to the summits,\u201d said Andrea Fischer, a glaciologist at the Austrian Academy of Sciences.<\/p>\n Seasonal snowfall, apart from replenishing ice lost during summer, protects glaciers from further melt by providing a white cover that reflects sunlight back out to atmosphere better than darker ice \u2014 sullied by dust or pollution \u2014 can do.<\/p>\n But at the Grand Etret glacier in northwest Italy, only 1.3 metres (4.2 feet) of snow had accumulated during this past winter \u2014 2 metres (6.6 feet) less than the annual average for the 20 years up to 2020.<\/p>\n This year\u2019s Alpine ice losses, registered even before the biggest melt month of August, surprised scientists to some extent, as many of the glaciers had already lost their lower-lying snouts. Because they had retreated up the mountain, where temperatures are cooler, scientists thought they should have been better protected.<\/p>\n \u201cYou can easily imagine the final results after summer will be \u2026 extensive loss of glacier coverage in the Italian Alps,\u201d said Marco Giardino, vice president of the Italian Glaciological Committee.<\/p>\n Data shared exclusively with Reuters shows that Morteratsch is now shedding about 5 centimeters (2 inches) a day and is already in a worse state than it would normally be at the end of an average summer, according to data from GLAMOS and the Universite libre de Bruxelles.<\/p>\n The nearby Silvretta Glacier has lost about 1 meter (3.3 feet) more than at the same point in 1947 \u2014 the worst year in its database stretching back to 1915.<\/p>\n Himalayan glaciers are also on track for a record ice loss year, scientists told Reuters. When the summer monsoon season arrived in the Kashmir region, for example, many glaciers had already been shrunk drastically, with their snowlines starting high up the mountain, after a March-May heatwave marked by temperatures above 48C (118F) in northern India.<\/p>\n An early June expedition in India\u2019s Himachal Pradesh found that the Chhota Shigri Glacier had lost much of its snow cover. \u201cThe highest temperature in over a century in March through May clearly had its impacts,\u201d said glaciologist Mohd Farooq Azam at the Indian Institute of Technology Indore.<\/p>\n Vanishing glaciers are already endangering lives and livelihoods. Earlier this month, a glacier collapse on the Marmolada in Italy killed 11 people.\u00a0read more\u00a0<\/a>Days later, a collapsing glacier in the Tian Shan mountains of eastern Kyrgyzstan triggered a massive avalanche, sending ice and rocks hurdling toward passing tourists.<\/p>\n Above the Swiss village of Saas Fee, a path leading to a mountain hut once passed through a summer snowfield on top of the Chessjen Glacier.<\/p>\n \u201cIt\u2019s too dangerous now,\u201d due to the risk of falling rocks, once held together by hard-frozen ice, said hutkeeper Dario Andenmatten while gazing out over a barren landscape dotted with glacial lakes. Nearby, the rumble of stones tumbling from the mountain could be heard.<\/p>\n Swiss residents worry that the glacier losses will hurt their economy. Some area ski resorts of the Alps, which rely on these glaciers, now cover them with white sheets to reflect sunlight and reduce melting.<\/p>\n Swiss glaciers feature in many of the country\u2019s fairy tales, and the Aletsch Glacier is considered a UNESCO World Heritage Site. Losing the glaciers \u201cmeans losing our national heritage, our identity,\u201d said hiker Bernardin Chavaillaz. \u201cIt\u2019s sad.\u201d<\/p>\n<\/div>\n[ad_2]\n [ad_1] MORTERATSCH GLACIER, Switzerland \u2014 From the way 45-year-old Swiss glaciologist Andreas Linsbauer bounds over icy crevasses, you would never guess he was carrying 10 kg of steel equipment needed to chart the decline of Switzerland\u2019s glaciers.
