Marine cloud brightening sounds so innocent until you realize it means secretly spraying salt water to dim the sun over thousands of square miles. 575 scientists say "maybe ask first?" when it comes to geoengineering governance.

Um Wasser wird in Zukunft erbittert gekämpft werden, keine Frage.
Diejenigen die es sich leisten können bereiten sich weltweit darauf vor.
Das wird die Salzlecke der Zukunft und dem "Feind" genau dort aufgelauert.
Nahrung, Wasser als Waffe zu nutzen, wird heute, in diesem Moment, vor den Augen der Welt getestet.
#China hat am Yarlung Tsangpo in #Tibet mit dem Bau des größten Staudamms der Welt begonnen. Das könnte weitreichende Folgen für die Verteilung von #Wasser in #Asien haben.
Ein solcher Staudamm steht im Zentrum eines Zukunftsszenarios, das @AnRinke und ich für unser Buch über drohende Kriege entworfen haben. Zu lesen gibt’s Wasser-Szenario und -Report auch bei @riffreporter (Abo oder bisschen scrollen für Micropayment)

And now that we have all read the explainer above on #ACC , the Antarctic Circumpolar Current(s),
we can better appreciate what Matt England explains here from about minute 50 onwards
https://www.youtube.com/live/39T7bW7KA18
He actually answers a question I put to him beforehand on Bluesky, regarding my confusion about salinification versus freshening.
The beginning of this #ClimateChat episode hosted by Dan Miller and Leon Simons
is all about Matt's paper with Rahmstorf and others about the 2023 bananas in the North Atlantic. You may recall: low wind speed as primary cause by far for the marine heatwaveS 2023 that gripped regions of the North Atlantic one after the other.
Matt explains the multiple ways wind over oceans contribute to cooling.
a) mixing b) white caps on the waves = albedo increase c) ocean spray or fog = albedo increase, and one more I now forget.
As is Dan Miller's habit, he also quickly asks Matt about #geoengineering, bringing SO2 into the #stratosphere .
Matt's reply: 1) angry that fossil fuel industry should be let off the hook by this
2) realistically, the political mindset lets Matt expect that geo engineering will be done.
3) whether he supports this is not answered.
4) as an afterthought, he adds that ocean acidification from relentless CO2 emissions does continue despite geo-engineering, and also the CO2 take-up and later re-release into the atmosphere continues.
Dan Miller also grazes his pet topic #ShippingSO2 . Matt politely agrees that it is a bananas factor – but a small one.
Then comes the Southern Ocean part (thank you!).
At which point the question is also raised and answered with a NO: whether seafloor #clathrate on Antarctica's continental shelf might thaw and cause a methane bomb.
And only one short moment at the end on #AMOC collapse, about which Matt also published a paper recently, namely the #collapse impacts non-Europe areas, such as teleconnections to adjacent basins and into the Southern Hemisphere
https://www.nature.com/articles/s41558-022-01380-y
I think, my question stole precious time from the AMOC part.
https://www.washingtonpost.com/climate-environment/2025/07/16/weather-modification-geoengineering-cloud-seeding-right/. I'm opposed to #geoengineering, because of its possible unintended consequences, but I'm also opposed to mad #conspiracytheories, especially of the kind promulgated by far right-wing lunatics like Marjorie Taylor Greene. I think #climate change needs to be tackled by very large reductions in #fossilfuel burning, ending #deforestation & the destruction of #wetlands.

Seien wir ehrlich: das gehört eh mal neu geregelt. Das ganze Warmwasser muss erst bei Singapur durch, was soll denn daran nachhaltig sein.

Excerpt: " 'While #governments and #corporations push us deeper into #ClimateChaos, movements around the world are rising,' she noted. 'From every corner of the Earth, women leaders are coming together with solutions and strategies to defend our planet and our communities. We call on governments and financial institutions to heed their voices and ensure effective and equitable policies—from Bonn to Belém and beyond. We must rise boldly, because climate change is not waiting for politics. Our movements are not bending. We are not breaking. We are defining and building a healthy and just future for all.'
"The new call to action points out that 'last year, the world breached this threshold with global average temperatures exceeding 1.5ºC above preindustrial levels. This alarming milestone is not yet a permanent breach of the Paris agreement guardrail, which refers to long-term warming, although scientists predict that 2024 will be the first of a 20-year period reaching 1.5ºC warming.'
" 'Although the pathway is drastically narrowing, the International Energy Agency affirms that the goal of the Paris agreement is still attainable,' the publication continues. 'Scientists assert that limiting global warming to 1.5ºC will require significant and urgent action from governments and financial institutions.'
"Specifically, the coalition outlined 10 broad actions for governments and financial institutions, beginning with urging both the public and private sectors to end fossil fuel expansion and extraction, and to 'reject false solutions, such as natural gas, mega-dams, geoengineering, bioenergy, forest offsets, carbon trading schemes, nuclear energy, biodiversity credits, and carbon capture and storage.'
"The collective also called for accelerating a just transition, promoting women's leadership and gender equity, protecting the rights of #IndigenousPeoples, safeguarding #forests and #biodiversity, preserving oceans and freshwater, advancing #FoodSecurity and #sovereignty, implementing the #RightsOfNature, providing robust climate finance, and cutting off financial institutions' support for 'harmful projects and redirecting resources into climate solutions.' "

Wirksame CO2 - Vermeidung wäre halt auch zu einfach...
"Ein internationales Team, unter anderem von der polytechnischen Universität Turin in Italien und dem KTH Royal Institute of Technology in Schweden, hat einen detaillierten Plan für eine Vorläufer-Mission entworfen. Wie in einer Studie im Fachjournal Science Direct dargestellt wird, soll die Mission die Schlüsseltechnologien für einen zukünftigen planetaren Sonnenschirm

#Geoengineering rettet den Kapitalismus und nicht das #Klima:
Beendigung des Klimanotstands? Nichts könnte einfacher sein: Lassen Sie uns ein Loch unter dem südlichen Ozean graben, um eine gigantische Atombombe zu zünden, die tausendmal stärker ist als die mächtigste Atomwaffe, die jemals gebaut wurde. Durch das Besprühen des Meeresbodens wird die Explosion es Basaltrümmern ermöglichen, große Mengen an CO2 aufzunehmen.

Artificial upwelling is a form of geoengineering that aims to use pipes and pumps to channel cool, nutrient-rich water from the deep ocean to the surface. In doing so, it could fertilize surface waters, prompting the growth of plankton, which can then absorb and store large amounts of atmospheric carbon.

Just as there's no planet B, there's no planet β.
There's simply no representative testing ground for geoengineering against climate crisis which has any hope of accurately representing the results as they would affect life on earth.
Neither planet wide or over any meaningful period of time.
Any kind of atmospheric manipulation or similar is a stab in the dark with the entire planet at stake.
