Two large glaciers in Antarctica, Pine Island and Thwaites, has reached a point of no return in terms of the melting process It reached a point of no return, experts confirmed after observations that a satellite took over.
This could collapse the shelf of West Antarctica with enough ice to raise the ocean level by more than three meters, according to a study published in the journal Cryosphere by researchers in Northumbria University.
“It simply came to our notice then Pine Island she had entered an unstable retirement stage had already been relieved, but our study is the first to confirm that it has exceeded this critical threshold“, He said Sebastian Rosier, who leads the study.
Both the glacier Pine Island and Thwaites they have been under surveillance for years because they both contributes about 10% to sea level rise, Explain Massimo Frezzotti, researcher at Italian National Agency for New Technologies (ENEA)
“So far, the glaciological models have not been able to reproduce the data that emerged from the satellite observations. The warning indicators extracted from the comments were reproduced in this model, which confirms that the thresholds they have already been overtaken due to the entry of warm water from the ocean”, Mrs. Frezzotti.
Maximum also explains that the water temperature in Antarctic is -2 degrees, but 2.3 degree water enters with a high melting temperature.
The collapse that this could cause would lead to Venice being completely under water, he continues Frezzotti: “This could collapse the cover and lead to a global sea level rise of three meters. Just to give an example of consequences, Venice would be completely submerged”.
