Two great glaciers of Antarctica, the Pine Island i Thwaites, they reached a point of no return as to the fusion process reached a point of no return, experts confirmed after observations that picked up a satellite.
This could collapse the platform of West Antarctica, with enough ice to raise the level of the oceans more than three meters, According to a study published in the journal Cryosphere conducted by researchers at the Northumbria University.
“The possibility that Pine Island had entered an unstable stage of retreat had already been relieved, however our study is the first to confirm that it exceeded this critical threshold“, He said Sebastian Rosier, Who leads this study.
Both the glacier Pine Island i Thwaites they have been under surveillance for years since both they contribute about 10 percent of sea level rise, explain Massimo Frezzotti, Researcher at the Italian National Agency for New Technologies (ENEA)
“Until now, glaciological models had not been able to reproduce the data that emerged with satellite observations. The warning indicators extracted from the observations were reproduced in this model, which confirms that the limit thresholds they were already surpassed, due to the entry of hot water from the ocean”, God Frezzotti.
Maximum also explains that the water temperature in the Antarctica is -2 degrees, however enter waters of 2, 3 degrees with high melting temperature.
The collapse that could cause this fact would lead to Venice being completely under water, he continues Frezzotti: “This could collapse the cap and lead to a global rise in sea level by three meters. Just to give an example of its consequences, Venice would be completely submerged”.
