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

#Stratospheric aerosol injection "could increase the reflection of #sunlight from a cloud 
by as much as 10%, which is much larger than we anticipated" https://research.noaa.gov/injecting-light-reflecting-particles-into-the-stratosphere-could-also-make-marine-clouds-brighter
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,...

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.

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."

#glaciology is also having this discussion, now on #geoengineering. Time for a new #Asilomar?

#KnowledgeByte: #Geoengineering, also known as climate engineering or climate intervention, is the intentional manipulation of the Earth's climate and environment on a large scale.
The goal is to prevent further #ClimateChange, slow down and reverse global warming, and mitigate the effects on the biosphere and civilization.

Is this the society part or the geoengineering part of the nsf panel getting deferred 'until further notice’?
One of my earliest, popular posts here on mastodon was about #geoengineering through #srm #SolarRadiationManagement through #sai #StratosphericAerosolInjection , or venture capitalist dudes from “Making Sunsets” tried to create fake Volcanoes in the stratosphere to cancel out some greenhouse gas fueled global warming.

Last fall #nsf convened a panel of experts including scientists like me plus social scientists and policy makers— virtually so very low-cost -- to figure out the impact of such a program (as well as other geoengineering ideas for carbon capture and marine cloud brightening etc.) on the world.
This email was in my inbox this morning, 'deferring' it indefinitely.
I hope someone IS INDEED convening these kinds of panels.
“Well this is modestly embarrassing.
I invited you to join a report-out from the NSF workshop you participated in last year and you kindly accepted.
You may be aware that there has been quite a lot of change at the NSF and other funding agencies following the recent alteration in administration. I have now been advised that the NSF will have to defer the report-out until further notice.
I know that the organising team are anxious to reconnect with the community and bring you up to speed. I can only offer my apologies for having wasted your time - like you I have very limited understanding of the current situation - but I will let you know as soon as things change.
With warm good wishes”
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.'
Controlled de-orbiting of #satellites at end of mission is a responsible practice and @SpaceX deserves credit for doing so.
But this entails depositing an unknown amount of material in the upper #atmosphere, with presently unknown #environmental effects. We don't know how much of which metals this involves, but "burning" things up in the atmosphere involves ablation and vaporization of materials. There are legitimate concerns that this may upset the thermal balance of the atmosphere, amounting to a giant uncontrolled #geoengineering experiment.
