If the world is heated by 2.7 ° C due to the current trajectory of climate policies, then only 24% of the world’s current-day glaciers will remain, a new study published in science indication that glaciers are more sensitive to global warming, which was earlier estimated.
The study states that global temperature increases to 1.5 ° C – as adopted in Paris Climate Agreement – can preserve 54% or twice the glacier mass.
The study in the study of blaston in the Swiss village of Blaton, exactly a day after a spacious part of a glacier, fell into the valley, most of the villages of a mountain in the foothills were buried.
The estimated figures in the study were for global landscapes, and were slanting by very large glaciers around Antarctica and Greenland. The study warned that even though the temperature has stopped rising today, the world’s glaciers will still lose 39% of their mass compared to the level of 2020, and this would increase the sea level of 113 mm.
Among the weakest areas, according to the study, Scandinavia had glaciers, western Canada and Rockies and European Alps in the US.
In Scandinavia, no glacier ice will be left at 2 ° C warming, while Rocky and European Alps would be left only 10–15% of the glacier warming levels.
Even at the level of 1 ° C warming, these areas will lose half of their ice, the study states.

“Our study clearly makes it clear that every fraction of a degree matters,” the co-main author Dr. Harry Zecory says.
He said, “The option we make today will be echoed for centuries, determining how much our glaciers can be preserved,” he said.
“Glacier is good indicators of climate change as their retreat allows us to see with our own eyes how climate is changing … (but) The situation for glaciers is actually worse than appearing in the mountains today,” co-author Dr. Lillians say to the Shoister of Insbrook.
Although Indian glaciers – especially in Western South Asia – show a less estimated loss of 5% under current warming, the study underlines that these areas are highly sensitive to extra warming. For an additional 0.1 ° C increase in global temperature between 1.5 ° C and 3 ° C, the loss of glacier increases rapidly-about 2%at the feature, about 2%, even with malignant losses in Indian sub-regions.

India’s major river valleys, Ganges, Indus and Brahmaputra-North India, have supported millions of livelihoods in the North East and Indo-Getic plains. In the Hindu Kush Himalayas, only 25% of ice from 2020 levels will be left at 2 ° C of warming.
To achieve these results, a team of 21 scientists from 10 countries used eight glacier models to calculate the possible snow loss of over 200,000 glaciers worldwide under a wide range of global temperature scenarios.
The study used advanced simulation at a multi-century time, which suggests that some glacier systems-especially in polar areas-may take up to a thousand years to fully respond to today’s climate.
