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.

Dispatch from Dystopia: 1 
Hello readers, it’s been a while since my last post. I’ve been busy proselytizing regenerative culture over at The Cultural Easton. What follows is a wandering exploration of the summer so far. I’ve titled it “Dispatch from Dystopia: 1,” as current events now clearly show the old world is not coming back. We’ve moved on. Systems are collapsing all around, and we’re just getting started.
This is the first in a series of quick updates I’m preserving for my children, nieces, and nephews. We may have entered a new phase of collapse, but that doesn’t mean we stop fighting. Right now, I’m on the first of three training sessions through Indivisible for mass defiance and civil resistance. Sustained resistance against authoritarian breakthroughs isn’t easy. But I won’t leave that fight to my kids. There’s a better way to live. All known life follows regenerative principles—except human systems.
It’s time we changed that.

The documentary Wasser, "Water" shows two installations of a fog water collector, one on a Portuguese island and one on a hill in arid North Africa.
The installation consists of a metal wire mesh standing upright on a hill, a collection vessel and a pipe to funnel collected water downhill to where people live.
Wind blows through the mesh. Moisture in the air condenses on the cool metal and the droplets run down into the collector.
This version here is a tad more elaborate than in the documentary

This new version uses hydrogel – a chemical compound, so very high-tech:
https://news.mit.edu/2025/window-sized-device-taps-air-safe-drinking-water-0611
We depleted ground water in many areas so the wire mesh idea is relevant in parts of Germany and Europe, too.
Not being able to dig a well as deep as needed due to depletion, and not being able to run pumps without electricity anyway, such a mesh, left behind by civilisation, might be a feasible solution for survivor communities after the #collapse.
Not as sole drinking water provision. Because if it were, they also couldn't live off the – then also dry – land and should better pack up and move elsewhere.
But I see use for the mesh installation for comfortable household access to water.
The ground water table will only take 200 years to replenish to pre-industrial levels.

You never thought you'd see this system fall
J'étais inquiet de l'effondrement sociétal dû aux coûts rédhibitoires associés au maintien des infrastructures inadéquatement conçues pour supporter les aléas climatiques qui viennent (ex flash floods!). Plus maintenant.
Ce qui entraînera la chute, c'est l'ubris de l'empire anglo-américain et la guerre déclarée contre la Chine (économique et bientôt réelle).
TL;DR: pénurie de transformateurs pour le réseau électrique.
I think #DraftKings should run a betting line on when the #economy will #collapse. Personally, I think it will happen before Christmas.
I can't quote totals, but based on social media & random news reports, 1000s of people have been fired from government jobs, 1000s more from support jobs. Add those numbers to the 1000s of immigrants who spend consumer dollars & the numbers of small businesses that are failing & there's no way the economy won't be run into the ground

We can acquaint ourselves with collapse.
Sara El-Sayeh, Post Growth Fellow, introduces the idea of micro-dreaming as a practice to build imaginative bridges between the current world and the one we want to inhabit.
In this beautiful digital zine and article, Sara offers inspiring reflections on the seas (and Cs) of collapse and instructions for how to begin micro-dreaming (full zine here): https://medium.com/postgrowth/acquainting-ourselves-with-collapse-b0e1333413db

@owgf.org Unfortunately, #civilisation is doomed in any event. If #climate change was the ONLY problem, it MIGHT be salvageable, but it's only one problem of many, including, e.g., the #biodiversity crisis, #overpopulation & the grotesque #economic #inequality between countries & individuals. There is also instability arising from #ethnic, #national & #religious conflicts. The term that gets used is #Polycrisis, & #collapse can't be averted.

[P] Third hottest June on record and the lemming-like typies of hiverarchy are still screexhing an "All's well!" as the world burns around them. I just want to be rescued and taken to a world wothout typies, because a world without typies is a world without hiverarchy, and a world without hiverarchy (enabling moronic Dark Triad megaparasites) is a world without evil. I'd like that.
Every day now we are inundated with these battles. Clips of masked men in unmarked cars ramming drivers and stealing them away. Clips of an agent demolishing a window with a tactical axe. Stories of agents chasing men into medical facilities and terrorizing them and employees. Brutal glimpses into an emerging and sobering reality.
