Its melting should result in up to three meters of sea level rise and all coastal areas should therefore be swallowed. And it could happen much sooner than expected ….
For those who are still skeptical of the consequences of global warming, the data shows us is likely to suffer an upheaval very soon.
In fact, the Thwaites Glacierlocated in Antarctica and nicknamed the glacier by scientists “Judgment Day”ie the glacier of the Apocalypse is about to dissolve much faster than expected.
Yes, those who study it had drawn the Wake Up a few months ago: the analyzes were already very worrying, but the phenomenon has significantly worsened.
Last December, large cracks portended the worst. And the research published on Monday 5 September in the journal Nature does not bode well, quite the contrary.
Because the melting of this glacier would be dramatic
It should be understood that this is the largest glacier on Earth. It extends 120 kilometers – is around UK size – and has a depth of about 800 to 1,200 meters in Antarctica.
Scientists have been studying it closely for many years to analyze the global forecast of sea level rise.
Up to 3 meters of sea level rise and swallowing of coastal areas
And most importantly, it contains enough ice to lift sea level above 65 cm if it came off and melted.
New #ThwaitesGlacier Research: High-resolution mapping of the sea floor in West Antarctica has revealed periods of rapid retreat in the history of the Thwaites Glacier, providing critical information on how it might behave in the future.

An elevation that would be even greater: up to three meters because the melting of this glacier will lead to the melting of the surrounding glaciers.
All coastal areas would therefore be completely submerged, which is almost worrying 40% of the world population.
Because according to the United Nations, about 40% of the human population lives less than 100km from the coast.
Worrying data collected
A team of researchers was thus able to study the melting of this glacier in a different way. So far, only satellite images have been examined.
But with the advances in technologysome kind of underwater robot was able to collect glacier information while going underwater.
And the data are not the most reassuring, they are very worrying.
Marine geophysicist and co-author of the study, Dr Robert Larter of the British Antarctic Survey, says: “The Thwaites Glacier is really hanging by a thread todayand we should expect to see big changes on small time scales in the future – even from year to year – once the glacier retreats past a shallow ridge in its bed. “
