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."

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

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?

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.

Webinar on polar #geoengineering and why it's such a stupid idea...
The paper it's based on is available here. But the key points basically say it all.

"As the atmosphere continues to fill with greenhouse gases from human activities, many proposals have surfaced to 'geoengineer' climate-saving solutions, that is, alter the atmosphere at a global scale to either reduce the concentrations of carbon or mute its warming effect.

One recent proposal seeks to infuse the atmosphere with hydrogen peroxide, insisting that it would both oxidize methane, an extremely potent greenhouse gas while improving air quality."

Researchers are proposing to bump the alkalinity of the ocean to increase it's ability to sequester carbon.
Um... no.
