Antarctic "Doomsday Glacier" is accelerating melting, and the current situation is at stake

[Global Times Comprehensive Report] The "Doomsday Glacier" located on the Antarctic Earth -Siwitz Glacier will accelerate the ablation in the next few years, and the current situation is at stake.

Antarctic Siwitz Glacier

According to a paper report on the 6th, a paper published on the "Natural Earth Science" on the 6th stated that scientists draw a map of melted historical trajectory for this glacier. Evolution. Studies have found that due to the influence of the earth's warming, the bottom of Siwitz Glacier is constantly suffering from warmth. At a certain time in the past, the bottom of the glacier began to fall off from the sea bed, and now it is melting at a rate of about 2.1 kilometers per year. This is Speed ​​is twice that scientists observed 10 years ago. Earth physicist Robert Ratt said: "Switz Glacier is really deducted from its 'nails'. In the short term, it is likely that after a few years, we can see that the glacier retreats to the sea bed to the sea bed. Outside the shallow ridge. "

Siwitz glaciers are over the United States Florida. If they are all melted, they are enough to raise the sea level by more than 4 meters, so they are called "Doomsday Glacier". (Luke)
