#Thwaites and #PineIsland #Glaciers Rapid Melting Could Cause Four Foot Global Sea Level Rise

March 4, 2020

"Over the weekend of February 8-9, 2020, a significant calving event was observed by the European Space Agency’s Sentinel satellites on Thwaites’ neighbor #PineIslandGlacier. A 120-mile ice chunk—approximately the size of three San Franciscos—broke off the glacier’s front and splintered into several smaller icebergs, one of which was huge enough to receive its own name, B-49. Pine Island Glacier’s unstable state is evidenced by the diminishing time between calving events; prior events this century happened in 2001, 2007, 2013, 2015, 2017, and 2018. Between Thwaites and Pine Island, the amount of ice lost from Antarctica’s ice shelves is rapid and indicates a serious future threat. Both are susceptible to the encroachment of warm sea level because the “grounding line,” where the glaciers meet bedrock, lies below sea level. These two glaciers form the gateway to a large supply of frozen water on land that if released into the sea would cause global sea levels to rise by an estimated four feet. Although Pine Island Glacier appears to have stabilized for now, the threat of an increasingly unstable ice shelf yielding larger and larger icebergs (marine cliff instability) may cause dangerously fast losses of ice in West Antarctica."

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.

If (when?) #Thwaites #glacier melts, 10 feet of sea level will submerge #Miami.

Ja. Wie das genau vonstatten geht, ist schwieriger zu kapieren und zu merken, als die Liste davon, was #ElNino und #LaNina in verschiedenen Weltregionen bewirken.

Dieses kurze Clipchen hab ich gestern erst entdeckt, und hab dadurch wieder ein bisschen mehr verstanden, wie das mit dem #ENSO funzt https://oceantoday.noaa.gov/elninolanina/
Aber genau erklären und begründen könnte ich es immernoch nicht. Dafür brauch ich wohl noch 10 Explainer...
Ging /geht mir bei #Thwaites auch so. Immer, wenn ich wieder was Neues dazu lese, eine neue Grafik sehe oder so, versteh ich ein bisschen mehr. Aber 1 paper allein oder 1 Pub-Sci-Artikel allein schafft das nie.

Yes, good read for me as layperson, too.
Ross gyre is a feauture new to me.It's 1000km2 in size and the picture on en.wikipedia locates it in the area that also spans the front of #Thwaites.

I have difficulties translating the location from Southpole view to this Mercator projection at Climate Reanalyzer.
Can you tell me, which part of the cold blob south-left of South America is the Ross gyre?

AAAS: "Dwindling sea ice may speed melting of Antarctic glaciers" 'February, on an icebreaker off the coast of West Antarctica, Robert Larter came on deck to a startling sight: open gray water as far as the eye could see.' Following day satellite survey found sea ice circling the continent had hit a record low. "Dwindling sea ice could strengthen a clockwise current called the Ross Gyre, bringing warm waters closer to land, hastening, collapse of the West Antarctic ice sheet, which locks up enough water to raise global sea levels by 3.3 meters," just over 10.8 ft. The warmer water + glacial melt resulting from a stronger Ross Gyre already show signs of slowing part of global ocean's overturning ciruclation, a critical “conveyor belt” of currents which both distributes heat + removes carbon dioxide from the atmosphere, double whammy. Until a decade ago the ice cover was actually expanding, then 'from 2014 to 2017, the ice began to vanish rapidly, losing more in 3 years than Arctic had lost in 3 decades.' It rebounded for a few yrs, then resumed its decline, reaching successive lows the last 2 yrs. The Ross Gyre in modeling shows the 'force of surface winds on newly exposed water strengthened the gyre and expanded it, according to a study published last month in Geophysical Research Letters.' The expanding, warming Gyre will warm the water under the Thwaites glacier + accelerate its deterioration. Not good news for the climate.   #antarctica    #thwaites        #climatechange

Global warming will be acknowledged once and for all if/when it impacts The Masters?
#Augusta, meet #Thwaites, she's got even more "pedigree", than you honey? More sweet tea?

Journey to the Doomsday Glacier in #antarctica
#thwaites could reshape the world’s coastlines. But how do you study one of the world’s most inaccessible places?

Reminds me of how I used to love #Longread journalism on all sorts of topics, like in the New Yorker for instance, or in German media.
But since I became climate-aware in 2018, I just didn't find my time well spent anymore on non-climate-related, or worse, non-climate-aware journalism. The latter is of course ALL journalism, except for 0.0001%. And the former, the non-climate-related journalism is factually non-existent as all topics have a big climate angle. 99.9999% of the journalists just don't know about the climate angle or blatantly refuse to cover it.
So since 2018, what I allow my time to be spent mainly on is scientific papers. And altho it satisfies my curiosity, and kindles even more curiosity, the reading experience is ofc simply not comparable to well-honed story-telling skills like Brown's voice.

"‘Everyone should be concerned’: Antarctic sea ice reaches lowest levels ever recorded - With the continent holding enough ice to raise sea levels by many metres if it was to melt, polar scientists are scrambling for answers - For 44 years, satellites have helped scientists track how much ice is floating on the ocean around Antarctica’s 18,000km coastline ... But across those four decades of satellite observations, there has never been less ice around the continent than there was last week ... “We are seeing less ice everywhere. It’s a circumpolar event. Hobbs and other scientists said the new record – the third time it’s been broken in six years – has started a scramble for answers among polar scientists.

The fate of #Antarctica – especially the ice on land – is important because the continent holds enough ice to raise sea levels by many metres if it was to melt ... “We are probably starting to see signs of significant warming and retreat of sea ice [in Antarctica]. To see it getting to these levels is definitely a concern because we have these potentially amplifying feedbacks.”

A Rare Look Below the ‘Doomsday Glacier’ Reveals Surprising Melting
Thwaites Glacier is often called "the Doomsday Glacier" because its collapse could cause catastrophic sea level rise. 

Researchers use a hot water drill on Thwaites Glacier, which two new studies show is melting in an unexpected manner. Icefin

Der Weltuntergangs-Gletscher #Thwaites hat tiefe Risse & sogenannte „Treppen“-Formationen gebildet, weshalb er noch schneller schmilzt.

Zerfällt der er, steigt der Meeresspiegel 65cm & setzt weiteres Eis der Arktis frei, was insgesamt etwa 3,5m bedeutet.
