Last month, the City of Alameda blocked scientists from continuing basic research into an experimental approach that may, one day, slow global warming.

The research was being done by atmospheric scientists from the University of Washington, and a nonprofit called SilverLining. SilverLining is funded by a consortium of philanthropic foundations and individual donors. Despite the researchers' credentials, the city council remained skeptical and voted unanimously to halt the work.

"We need to know more about this before you come to our city and start these experiments," concluded Alameda Mayor Marilyn Ezzy Ashcraft.

Marine cloud brightening is a scalable potentially majorly helpful mitigation strategy to keep us from going completely off the tipping points rails and this dip shit city council said you can't do research because you haven't done enough research

California is Not In My Back State, the State.

"No one has control over what people do in different parts of the world. There is no regulation in place. There's no global treaty in place about this technology that regulates this technology," remarked Lisa Dilling, an associate chief scientist with the Environmental Defense Fund.

At this point, she says, no one knows enough to safely deploy cloud brightening or any other form of solar radiation modification, also known as solar geoengineering.

"We absolutely think now is the time for doing research on the impacts of the technology," said Dilling.

The nonprofit fund announced it will finance the research, issuing grants to teams around the world in order to better inform governments, scientists and the public. The first grants will be issued after Oct. 1.

"We feel like we need to have strong scientific understanding before any decision is made about this," Dilling said. "That could be a decision to not to use the technology in the future. It could be decision to use the technology in the future."

This must have been cherry picked or taken out of context. No one could possibly be worried about this at the scales that are possible right now, they must be talking about future hypotheticals and not some salt sprayed off the deck of a boat.

The leading possible source of additional cloud condensation nuclei is salt from seawater, although there are others.

I wonder if this could present a possible solution to the huge amounts of highly concentrated brine that de-sal plants produce. AFAIK every de-sal plant creates a big death zone wherever it dumps the brine left over after it's pulled much of the water out of seawater. Maybe hte could, idk, spray the brine out over land, let it dry, collect it, and dump it in to the clouds where it'd end up back in the ocean dilute enough to no longer be a problem. Kill two canaries with one coal mine.

The comparison I most often see is that marine cloud brightening could potentially offset the loss of the aerosol masking effect from sea shipping companies cutting sulfur from their fuels. The aerosol masking effect is estimated to be somewhere between 0.5–1⁰ C which is now being realized. So Marine cloud brightening could, potentially at an astronomical scale, could offset that. Or we could put sulfur back in the fuels I guess lol

and then keep ramping it up so that we can continue burning fossil fuels until we're masking 2-3 c in warming and then there's an economic slowdown and we can't keep up the geoengineering and suddenly it's mask off on however many extra decades of warming got baked in meanwhile

the research is good, but geoengineering initiatives under capitalism are a death sentence
