Solar Geoengineering

“You'd probably like a few in the, a northern hemisphere, a few in the southern hemisphere. I would say two or three on each hemisphere, and maybe one around the equator. Should be enough.”

“So in, in terms of giving orders of magnitude or estimates, and we have a very detailed breakdown for every million tons of particles that will be Dispersed, the cost will be roughly ten billion dollars, and you'll get half a degree of cooling.”

“I believe that having a safe option essentially lowers the risk That people will go the wrong way because there is an alternative. Or to say it otherwise, if we didn't have options, I would say that the likelihood that someone would go the wrong way would be m…”

“I would argue that, you know, Having no option is not a good balance for this. You need to have options. You want to make sure that you are not stuck in a position that in 10 years from now, people are saying, why no one worked on, on giving us option?”

“They are the potential for Solar geoengineering to become a kind of techno fix that is, ah, latched onto by particular economic and political actors to delay, ah, mitigation and energy transitions, the fossil fuel industry, and in so doing, that becomes a kind…”

“I think a swift regulatory or political backlash to, like, totally unfettered solar geoengineering is probably the right thing.”

“I mean, I suspect that that will happen. I suspect it'll be done by a, some country, not, not by a lone billionaire. Blown billionaire makes for a better novel. Country is a more realistic possibility.”

“So there are absolutely no small scale or large scale experiments going on anywhere on the planet.”

“By cooling with these methods or with any methods, we would not be just turning back the dial of time to a time where there was less CO₂, because the sulfates do cool differently than the CO₂ warps. And even if maybe we can try and get it as close as possible,…”

“It might still, and it probably is still going to be better than not doing than letting the warming just keep unchecked.”

“I do not think personally that in the 20 years are going to be enough to scale CDR solutions in a really, in a way that would really make an impact.”

“There's a lot of agreement over the fact that the governance part is actually the hardest part when it comes to solar geoengineering.”

“This could be another one of the things where it is maybe unlikely that a single actor could do it because, as one reviewer once pointed out to me, you can shoot the planes out of the sky.”
