By 2100, Greenland will suffer the highest glacial loss in the last 12,000 years
The current rate of loss has already caught up with that of the warm period 12,000 years ago. The glacial layer in the images has advanced and receded many times over the last millennium. However, recent studies show that the rate of loss has reached its highest rate in the last 12,000 years.
Greenland will lose much more ice by 2100 than in the last 12,000 years, according to the scientists’ report in the journal Nature on October 1.
Since 1990, Greenland has been losing glaciers at an ever-increasing rate. Glacier loss on the island raises world sea levels by about 0.7 millimeters each year. So, how does this rapid loss of glacier compare to hot periods lasting 3000 years?
Glacier geologist Jason Briner, from the University of Buffalo in New York, and his colleagues have drafted an ice change schedule of nearly 12,000 years from the beginning of the Holocene universe 11,700 years ago to 2100. The researchers combined the simulated climate and glacial physics with eyes of the dimensions of ice sheets marked with glacial cliffs.
These cliffs are a mark of the borders of the historic glacial plains. Recalibrated climate simulations, including spatial changes in temperature and precipitation across the island, contributed to recreating historical temperature changes.
Greenland lost about 6,000 billion metric tons of its glaciers every century during the hot period between 10,000 and 7,000 years ago, the team estimates. However, these rates are almost the same as the rate of loss in the last 20 years, about 6,100 billion metric tons per century.
Experts state that this speed will increase even more in the next century. Future greenhouse gas emissions are vital for this rate. They predict that this rate, which is approximately 8,800 billion metric tons per century in a low-rate greenhouse gas emission scenario, could reach up to 35,900 billion metric tons in a high emission scenario.
Briner; states that low oscillation can slow this loss, but whatever people do, glaciers will suffer the biggest loss in their history.
