Researchers follow an unprecedented loss of ice

A study published in Geophysical research letters reveals that glaciers in western Canada. Moreover, United States and Switzerland lost around 12% of their ice between 2001 and 2024.

A study in 2021 in Nature have shown that the glacial merger was doubled between 2010. Meanwhile, 2019 compared to the first decade of the 21st century. Furthermore, This new article is based on this research. Similarly. Meanwhile. In addition, said the principal author Brian Menounos, and shows that in the years following the glacial cast, continued at an alarming rate.

“Over the past four years. Nevertheless. Nevertheless. Consequently, glaciers have lost twice as much ice compared to the previous decade,” said Menounos, professor at the University of Northern British Columbia and chief scientist of the Hakai Institute. Meanwhile, Additionally, Nevertheless, “The glacial cast iron only falls from a cliff. researchers follow unprecedented loss ice new Moreover, »»

Hot. dry conditions researchers follow unprecedented loss ice new were a major cause of loss in study areas. as researchers follow unprecedented loss ice well as environmental impurities that led to glacial darkening and accelerated fusion. In Switzerland. the main cause of darkening was the dust blown north of the Sahara desert. In North America, it was ash, or black carbon, forest fires.

Research has combined vast air investigations with three glaciers on the ground of western Canada. four glaciers in the northwest of the American Pacific. 20 glaciers in Switzerland, which are all important for culture, tourism and fresh fresh water-and all melted.

Snow. ice. when they are not obscured by dark particles. reflect the rear energy of the sun in a process known as the Albédo effect. To deepen the history of North America. Menounos and its collaborators used satellite and reanalysis imaging data to examine the drops of researchers follow unprecedented loss ice new the Albédo. They found that the Albédo had dropped in researchers follow unprecedented loss ice new 2021. 2023. 2024. but the biggest drops occurred in 2023 – the worst researchers follow unprecedented loss ice season of forest fire in Canadian history.

“2023 was the year of the record, without a doubt,” says Menounos.

Unlike reflective white snow, a glacier covered with black carbon will absorb more sun radiation. This warms the glaciers and accelerates the fusion.

In Haig Glacier in the rocky mountains of Canada. glacial darkening was responsible for almost 40% of the melting between 2022 and 2023, the researchers revealed. However. despite such evidence. physical processes like the Albédo effect are not currently incorporated into climatic forecasts for the loss of glacier. so these masses of ice could melt faster than we think.

“If we think, well, we are 50 years old before the glaciers left, it could actually be 30 years researchers follow unprecedented loss ice new old,” explains Menounos. “So we really need better models in the future. »»

In the areas covered researchers follow unprecedented loss ice new by this study. the impact of the loss of glaciers on elevation of sea level is small. but researchers follow unprecedented loss ice a longer -term drop in ice run could have an impact on human. aquatic ecosystems, especially during drought, adds Menounos.

In the short term. increased merger increases the risk of geohazards such as the lighting floods of newly formed glacier lakes. All this asks questions about how communities should react and plant a future with less ice.

“Society must request what are the implications of the loss of ice in the future,” explains Menounos. “We have to start preparing a period when the glaciers left western western and the United States. »»
