'Poised to disintegrate': Antarctica's '#DoomsdayGlacier' is set to lose its #IceShelf this year
#WestAntarctica's "Doomsday Glacier" is on the brink of losing its ice shelf, further compromising the already melting ice mass and threatening to unleash devastating sea-level rises.
By Patrick Pester
"A vital ice shelf is about to break away from Antarctica's "Doomsday Glacier," further destabilizing one of the world's largest and most vulnerable glaciers.
The #ThwaitesGlacier is nicknamed the "Doomsday Glacier" because its collapse would send so much ice into the Southern Ocean that #GlobalSeaLevels would rise by 2.1 feet (65 centimeters or 26 inches), flooding coastal communities worldwide. This collapse could take centuries, but there is an imminent threat to Thwaites' eastern ice shelf, which will likely accelerate the glacier's demise.
"Researchers say that satellite images reveal that the Thwaites eastern ice shelf is about to detach from the glacier, New Scientist reported last week. While the glacier sits on land, the ice shelf is a floating body of ice that is attached to the glacier's mouth. Researchers still have a lot to learn about the glacier, but this shelf acts as a buttress, restraining the flow of ice from the glacier into the sea."
[...]
"Thwaites Glacier's slow collapse is part of a wider concern among scientists for the future of the West #Antarctic ice sheet. Thwaites is a key pillar of the ice sheet, protecting other ice from slipping into the ocean. If the whole ice sheet were to go, sea levels would rise by 10.8 feet (3.3 m), according to the British Antarctic Survey. The collapse of ice sheets like this one are considered tipping points, or 'points of no return,' in the fight against climate change — meaning that once they are crossed, they bring about permanent changes that cannot be reversed for many thousands of years."

The Dutch were already fucked, but now they are even more. But who cares about the Dutch, let's concentrate on the disasters going to happen in Bangladesh and other critical locations in the Global South.
Dr. Gilbz: *Antarctica might raise sea levels more than we thought*
https://youtube.com/watch?v=7THoXri-kdg
"The West Antarctic is currently chucking a load of ice into the ocean, adding rapidly to sea levels. And now, three new scientific studies have shown that the ice sheets may be more sensitive to warming than previously thought. These new findings could revise our sea level rise estimates upwards. I spoke to Dr Alex Bradley, who was involved in two of these new studies, about what this means, and why it doesn’t mean we should give up on climate action. Speaking of which... "

Interesting story at The Atlantic

about a #geoengineering idea to prevent #SeaLevelRise by grounding glaciers.Inspired by the history of the Kamb Glacier:

Slawek Tulaczyk wonders if the same could be deployed for #thwaites
https://www.scientificamerican.com/article/can-geoengineering-save-the-world-s-ice/Invest billions to keep #WestAntarctica buttress glaciers grounded to save trillions from rising seas?

Technofantasy (as Twila Moon says) distracting from the real work of reducing GHG emissions? -
Ocean water is rushing miles underneath the ‘#DoomsdayGlacier’ with potentially dire impacts on #SeaLevelRise
By Laura Paddison, CNN
Published May 22, 2024"The #ThwaitesGlacier in #WestAntarctica — nicknamed the 'Doomsday Glacier' because its collapse could cause catastrophic sea level rise — is the world’s widest glacier and roughly the size of Florida. It’s also #Antarctica’s most vulnerable and unstable glacier, in large part because the land on which it sits slopes downward, allowing ocean waters to eat away at its ice.
"#Thwaites, which already contributes 4% to global #Sea Level rise, holds enough ice to raise sea levels by more than 2 feet. But because it also acts as a natural dam to the surrounding ice in West Antarctica, scientists have estimated its complete collapse could ultimately lead to around 10 feet of sea level rise — a catastrophe for the world’s #coastal communities."

Already at today’s 1.2°C global warming, we cannot rule out that the ice sheets of #Greenland and #WestAntarctica may pass their TPs eventually, resulting in several meters of committed long-term #SeaLevelRise, and that parts of #Permafrost become subject to abrupt thaw. /5

Global Sea Level rise projections grossly under-estimated says major peer reviewed science #Cryosphere report, 'Two Degrees is Too High'. Report is by International Cryosphere Climate Initiative, estimates that 12 to 20 metres is likely from a 2C rise in temperature with eventual dissolution of most of Greenland, West Antarctica and parts of East Antarctica.
"We cannot negotiate with the melting point of ice."

The ground beneath #Antarctica's most vulnerable #glacier has been mapped for the first time, helping scientists to better understand how it is being affected by climate change. Analysis of the geology below the #Thwaites #Glacier in #WestAntarctica shows there is less sedimentary rock than expected—a finding that could affect how the ice slides and melts in the coming decades.

@osma Se olisi aikamoinen pala purtavaksi... ymmärtääkseni vesi virtaa keskimäärin ulospäin, koska suuret joet lisäävät niin paljon vettä Itämereen. Tarvittaisiin mittava pumppaamo!
