A new study warns of this Antarctic mega-glacier 120 km wide and 600 km long whose melting is accelerating and which alone would raise the waters of the oceans by 1 to 3 meters. Explanations.
While our eyes are focused on Hurricane Danielle (will come, won’t come? Damage, no damage?), one of the greatest environmental threats to humanity in the very medium term could come not from the Atlantic Ocean, but from the regions of the South Pole.
It is called Thwaites, but it is also called the “Glacier of the Apocalypse” because of the disastrous consequences for humanity if this glacier were to detach from the Antarctic continent. 600 km long, 120 wide, this behemoth threatens to tip over into the ocean. On its own, it is likely to raise the level of the oceans by one to three meters, recalls The Midi Dispatch.
And that’s what it’s doing: due to global warming, “Thwaites is really clinging on” to the continent, warns a team of scientists in a recent study published on September 5 in Nature Geoscience. In question, hot currents diverted by climate change which accelerate its melting. According to Geoa previous study had highlighted the imminent rupture, within 5 years, of the part of the glacier which still held it to the Antarctic continent.
This news only confirms the previous one: scientists were able to measure, using an underwater robot, the evolution of a glacier of gigantic proportions which melts two times faster than estimated between 2011 and 2019, i.e. 2.1 km per year currently. Suffice to say that it melts faster than expected, and that“a similar quick withdrawal will probably happen in the near future”warn the scientists quoted by TF1. Making it more than likely, in the years to come, its fall and then its drift in the oceans. With an inevitable rise in water levels, from 1 to 3 m, whereas according to the UN, more than 40% of humanity lives less than 100 km from the coast.
