Wir wissen, dass die Debatte um #GeoEngineering an Fahrt aufnehmen wird, weil das Klima halt kaputt ist, und wir jetzt magische Lösungen suchen.
Was mir neu ist: dass Geoengineering neuerdings als "climate repair" geframed und schöngeredet wird

This is not #climaterealism. It is #climatedelusion.
The new “ #centrist consensus” on #climate is emerging & its highly nationalistic, flirting with more #military involvement, & expecting at least 3°C of warming, thereby justifying #geoengineering.

#Stratospheric aerosol injection "could increase the reflection of #sunlight from a cloud 
hmmmmmm!
>In July 2012, a renegade American businessman, Russ George, took a ship off the coast of British Columbia and dumped 100 tons of iron sulfate dust into the Pacific Ocean. He had unilaterally, and some suggest illegally, decided to trigger an algae bloom to absorb some carbon dioxide from the atmosphere — an attempt at #geoengineering, a tech-based approach to combating climate change. It was a one-off, the largest known geoengineering experiment at the time,...
Bzgl. (eskalierender) #Klimakrise mit steigender Erderhitzung (mit zeitgleich starken Fortschritten bei Erneuerbaren) wundert es mich schon, dass #Geoengineering nicht stärker erwähnt wird? Ist ja schon die Selbstverteidigungs-Option kommenderer Generation? https://workwhileclimate.at/solar-geo-engineering-der-extrem-riskante-notfallplan-der-menschheit/

Das über "#Chemtrails" hat mich traurig gemacht. Leider kenne ich solche Gespräche auch. Meine gefrustete Antwort ist dann: "Ja, du hast recht. Flugzeuge hinterlassen chemische Spuren. Wasserdampf, #CO2 und was sonst noch bei der Verbrennung von Kerosin entsteht. Damit betreiben wir unabsichtlich #Geoengineering. Wir erhöhen die globale Durchschnittstemperatur auf für uns unerträgliche Werte. Das kannst du so weitererzählen und vielleicht sogar zusammen mit #FFF demonstrieren.
Am Donnerstag, den 27. März 2025 wird Holm Gero Hümmler das #PAN-Branchentreffen der Phantastik eröffnen. Die #Keynote zum Thema #Verschwörungsmythen findet im Congress Center zur #LeipzigerBuchmesse statt.
Bernd Harder nutzt die Gelegenheit um uns in Erinnerung zu rufen, wie sich manche #Verschwörungserzählung schon in den Köpfen etabliert hat.
Um yeah. Sounds like a great idea! <sarc> And if it doesn't work, we can just vacuum the stuff out of the sky with a giant dustbuster! And yeah -- I totally trust secretive Israeli nuclear scientists to look out for people and the planet!
A Mysterious Startup Is Developing a New Form of Solar #Geoengineering
Stardust, an Israeli–US startup, intends to patent its unique aerosol technology for temporarily cooling the planet.
Mar 22, 2025 7:00 AM
"The company is led by CEO and cofounder Yanai Yedvab, a former deputy chief scientist at the Israel Atomic Energy Commission, which oversees the country’s clandestine nuclear program."

#WTF #ClimateChange #Geoengineering?
I missed this comment on solar #geoengineering from @climatebook.bsky.social when it came out 10 days ago:
https://www.theguardian.com/commentisfree/2025/mar/12/solar-geoengineering-uk
#science #ClimateCatastrophe
"Sara Nawaz, research director at American University’s Institute for Responsible Carbon Removal, said she understood why scientists sometimes struggle to connect with communities and gain their support. Early research shows the public is reluctant to the idea of “engineering” the climate.'
Meta-note: research into public communications suggests that discussing #geoengineering motivates desire to avoid neeeding it all, to clean up one's act.
Klingt wie Science Fiction: Dank Solar #Geoengineering soll die #Sonne verdunkelt und so die #Erde abgekühlt werden – zumindest in der Theorie. Unternehmen wittern ein Milliardengeschäft, doch die Risiken sind nur schwer abschätzbar. @elena_matera #umwelt https://www.riffreporter.de/de/umwelt/solar-geoengineering-klima-loesung-usa-grossbritannien-trump
John Moore has been one of the main people investigating geoengineering solutions to slowing glacial retreat. It is interesting to see this paper from his group that says that geoengineering will not work to slow the retreat of Sermeq Kujalleq glacier (Jakobshavn Isbræ). https://doi.org/10.1038/s43247-025-02120-8
"That the trials are described as “small scale” is little comfort, because even small-scale trials risk developing the technology somebody else (think Musk, Trump or Putin [*]) might use for a large-scale deployment.
…
There is extreme danger in launching such field trials into an environment with neither national nor international governance in place."

Excellent episode of Science In Action.
Thoughtful + alarming on #H5N1 but piece on self regulation by genetic scientists was super interesting:
#glaciology is also having this discussion, now on #geoengineering. Time for a new #Asilomar?

No, we can’t geoengineer our way out of the climate crisis – Big Think…
The primary causes of global climate change are all due to human activity. Adding aerosols to our atmosphere only exacerbates the problem... #geoengineering #climatechange #globalwarming #parisagreement
Massive #geoengineering in the ancient #Amazonian habitat
'...ancestral Amazonians systematically built up large urban centres and engineered the habitat to their needs and appetites with composted gardens, fisheries, and forests groomed into orchards in complex, sustainably run systems – which could offer lessons for modern cities.'
