Climate change is shrinking glaciers faster than ever, with 7 trillion tons lost since 2000

Climate change speeds up the melting of mountainous rivers in the world, according to a huge new study and found that it reduces more than twice the speed in the early first decade of the twentieth century.

The ice rivers in the world lost snow at a rate of about 255 billion tons (231 billion metric tons) annually from 2000 to 2011, but that accelerated to about 346 billion tons (314 billion metric tons) almost annually during the next decade, according to the study in This week magazine magazine.

In the past few years, The Melt accelerated more, with 604 billion tons (548 billion metric tons) in 2023 last year.

The study was based on an international effort that included 233 in appreciation of changes in the weight of the iceberg. In all, the ice escapes in the world have lost more than 7 trillion tons of ice (6.5 trillion metric) since 2000, according to the study.

“The thing that people should be aware of and perhaps their anxiety is that yes, the ice rivers are already declining and disappearing as we said. William Kuljan, the ice scientist in the geological survey of Denmark and Greenland and one of about 60 authors of the study, said that the rate of this loss is accelerating.

Ice rivers in Alaska melts The study found that the fastest rate in any of the 19 regions that were studied, and lost about 67 billion tons (61 billion metric tons) of ice per year, resulting in the largest ice loss in the network.

The newspaper said that the ice rivers in Central Europe lost the highest percentage of ice in any region, and it is now 39 % smaller than it was in 2000. College said it worries more than the Alps because “it was” high summer temperatures The Alps. “

Fifteen years ago, scientists were more worried than others It disappears in the endKuljan said.

“Ice rivers are non -political and unbiased Climate change guards“Their retreating a clear picture of the accelerated warming,” said Join Flapers, a professor of Earth Sciences at Simon Fraser University in Canada, who was not part of the study.

The ice scientist Colorado Ice Tid Skambus, who was not part of the study, said the ice rivers shrunk and grew in the past for well -understood local reasons that were not climate change. He said: “What is happening now is different and clear,” it is due to the increase in greenhouse gases caused by coal, oil and natural gas. … There is no amount of discourse, tweet, or advertising that will change that. “

Scambos, flowers, and other external scientists described realistic and accurate evaluation, however Not surprisingly.

Kuljan said that many places-such as those in the West, see additional water now from fast ice rivers and benefit from this reinforcement, but that will disappear soon while the ice rivers melts beyond the point of no return.

The melting of the ice rivers contribute to the rise in sea level than the ice loss in either Greenland or Antarctica. The paper said that the expansion of water only because it rises is playing a larger role in sea level rise.

The average loss of total ice rivers is similar, perhaps slightly lower than those in previous and less comprehensive studies. Kuljan said that this new work may lead to new predictions that will be more depressed in the future due to better information and warming.

“If you are losing 5.5 % of the global ice size for more than 20 years, it is clear that this is not sustainable,” said Col. “This will catch you.”

Kuljan said that more than 600 billion tons of ice losses in 2023 “seem amazing now, but it might seem very normal for 10 years from now.” “The mountainous mountain rivers as a whole can quickly turn to mass ice loss.”
