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.

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

I think, my question stole precious time from the AMOC part.

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

@jwildeboer well then why use aluminium and not gold? Also it would have to be further up in the atmosphere.

I don't know if there is anything geoengineering related for aluminium and all the other components of the starlink satelites.

@sundogplanets
Ahh, they are for #geoengineering, not communication.

@mongabay What could possibly go wrong? #geoengineering #askingforafriend
