A new study has revealed that the Antarctic ice sheet can pass the extinction point in as little as 10 years due to global warming, revealing the sad state of the world’s climate and ecosystem once again . ) revealed.

In other words, this means that the point of no return for ice sheet destruction came much sooner than anticipated and we may already be in the middle of this process. Considering that the sea level is rising globally and the natural habitats of animals in Antarctica are on the verge of extinction , it is certain that this will have very serious consequences .

Results match previous ice loss patterns

Get a better idea of ​​how dire the situation is right now. On behalf of the researchers, the researchers examined the past 20,000-year of the continent’s last history, up to the last ice age, through ice samples extracted from the seafloor. As they leave Antarctica, the icebergs float in a large channel known as “ Iceberg Alley ” (Iceberg Channel). Debris from these icebergs also accumulates on the seafloor, providing researchers with a ‘historical record’ about 3.5 kilometers (2.2 mi) underwater . Combining this natural logbook with computer models of the ice sheet harekedollar series, the team identified eight stages of ice sheet retreat over the last millennium. In each case, the destabilization and subsequent rebalancing of the ice sheet took place over a period of about ten years.

paleoclimatologist Zoë Thomas of the University of New South Wales in Australia, “Our study shows that in the past, when the ice sheet retreated, periods of rapid cudollarse loss only were very abruptly within a decade or two . “Interestingly, after the ice sheet continued to recede for several centuries, this rapid loss of cudollarse stopped again in just a few 10 years,” adds.

Considering that the current change in the Antarctic ice sheet is in line with the past events described by the researchers, this is already in the midst of a new tipping point as we have seen before elsewhere in the world and in the Arctic It means we can be. According to the researchers, more evidence for these tipping points can be found in previously analyzed samples from the region, and this latest study also matches earlier patterns of ice sheet loss in the region . Commenting on this issue, geophysicist Michael Weber of the University of Bonn in Germany said, “Our findings indicate that the acceleration of Antarctic ice floe loss in recent decades marks the beginning of a period of self-sustaining and irreversible ice sheet retreat and significant global sea level rise. The increasing number of proofs showing that he can do it is consistent” .
