Cool article about 2 new papers, one a literature review and one a paleo view
https://www.theguardian.com/us-news/2026/may/04/new-orleans-sea-levels-relocation-climate-crisis

Good German article https://www.derstandard.at/story/3000000319484/new-orleans-muss-in-absehbarer-zeit-wohl-umgesiedelt-werden

But in sea level articles I always miss why this should be a problem and be addressed today. 30cm for New Orleans by 2100 doesn't sound much. What are the actual impacts? A flooded basement at king tide? So what? I don't get it.

In IPCC AR6-WG2 one learns that #by2030, Bangladesh has to relocated 2/3 of her Southern fossil power plants due to sea level rise. You read that right: by 2030.

So there's one hint why 30cm can be a real problem: corrosion via saltwater intruding from below. and from the surface inflow.

Another is soil: saltwater renders agricultural land unusable, 1 flood event is enough. Dunno why this is so.

And there's another factor: if you think in 3D, imagine that all the coastal ocean area gets the added power of 30cm more water forcing its way inland during tides? And during storms!? When the waves crash against beaches or dams, and with this much more force from the tons and tons of more water… WHAM!

‘Point of no return’: New Orleans relocation must start now due to sea level, study finds

AR6-WG2 says, Bangladesh must move 2/3 of her Southern power plants by 2030, to escape erosion from saltwater.
By 2030... !

And saltwater creeping up river deltas kills the soil and groundwater aquifers.

I find it also very difficult to imagine the damage to our civilisation from sealevel rise. But it's really very real. And not centuries away either.
The "factories of our civilisation" are all in regions with massive numbers of exposed and vulnerable=poor coastal populations.
Where do they go when their veggie garden and rice paddy yields no harvest anymore, and coral reefs die along with fish stocks.
Sudden urbanisation creates tensions, unless a suitable political culture and resource availability prepare infrastructure and social politics to prevent upheaval.
Each failed state lowers production capacity for all our complex supply chains, with huge follow-up impacts in our societies here in Global North.

The threat from #SeaLevelRise to our civilisation is very real.

@Bellingen

Reminds me of having read that tourism on Australia's east coast will suffer major losses as soon as #by2030 .
In AR6, IPCC report by Working Group 2 .

Came across it in a fulltext search for
"by 2030".

@muellertadzio

Nö, möchte ich nicht erklären. Weil ich nämlich gar keine Kritik an Deiner Arbeitsthese anbringe.
Ich spinne Deine Idee doch weiter!

...
Komisch, dass trotzdem so viele meinen, Angst zu schüren würde nur lähmen, aber gewänne keine Wahl.

Vll haben Grüne und LINKE noch nicht genug Angst, weil sie gar nicht genug wissen? Ohne Wissen kann man keine Angst schüren und keine Wahl gewinnen.

Sollen wir mal AR6-WG2 aus der Versenkung holen?

Unten ist ne Collage aus Tweets zum Hashtag #by2030 . Für das Projekt hatte ich damals in der Entwurfs-Version von AR6-WG2 ne Volltextsuche zu "by 2030" gemacht und die Treffer gescreenshottet.

@ArneBab @rahmstorf

Vll kopier ich das Projekt #by2030 hier ins Fediverse.
Dieses mal muss ich auch nicht noch mal grübeln, was dieses und jenes für die erweiterte Region und die Welt für Folgen haben wird, und auch nicht trauern und verzweifeln, wie beim ersten Run auf Twix.

@ArneBab @rahmstorf

Eine Collage einer Auswahl findest Du unter #by2030 auch hier im Fediverse.
Alle Tweets aus dem Projekt vermutlich hier: https://x.com/search?q=from%3Aanlomedad%20%23by2030&src=typed_query&f=live
Die einzelnen Screenshots hab ich auch noch auf der Platte, nehme ich an.

@ArneBab @rahmstorf

Auf Twix hatte ich ein Projekt unter dem #by2030 , wo ich Textstellen mit Screenshots aus AR6-WG2 gepostet hatte. Es gab aber keine Interaktion. Und da es für mich persönlich zu stressig war, diese furchtbaren Folgen, die so nah in der Zukunft schon liegen, allein im stillen Kämmerlein zu verarbeiten, hab ich das Projekt einschlafen lassen.
WG2 wurde überhaupt nicht von der Presse beackert. Gar nicht.
Das einzige, was Coverage bekam, war WG3 – die Ökonomen also mit ihrem erbärmlichen ÖkonObszön.

Over on the birdsite, I had started a project with quotes from #AR6 #WG2 for prognosis "by 2030" or "by 2040". You know, as #scicomm to increase awareness and risk perception.
I couldn't finish the project bc it was too much...
You can find all the posts here https://nitter.net/search?q=from%3Aanlomedad%23by2030&src=typed_query&f=image
Now I'm thinking, with the revamped Final Version out, I should do it again. Fulltext search for #by2030 #by2040 or "1.5ºC" and toot quotes and screenshots.
Maybe #IPCC censorship has reduced risks #by2030 😁

In the FAQ to #AR6 #WG2 chapter 9 on Africa, the Final Draft had stated that

250 million Africans will experience high water stress by 2030 #by2030 and up to 700 million be displaced as result https://nitter.net/anlomedad/status/1552933679130972161

Yesterday I happened to
realise that WG2 had published the final version by now, dunno when, maybe during COP?
Important and big changes have been made. Would love to see the feedback documents that caused the changes. HelP?

⚠️ And the 700 million vanished from the report⚠️
