“This example of the shipping regulation should really be Can really tell us a lot about this, right? So, because we're, we are claiming that this effect is maybe there, but it's small, and a lot of climate scientists are sort of saying already, in a way, before having done the research, because maybe that's their best guess, that well, yeah, sure, this might have had a tiny effect on global temperature, but it's unlikely to have had any contribution to any Parts of the system, right? It hasn't contributed to heat waves this summer. That might be very well true, but then if that is true, that does tell us a lot about what would be a permissible geoengineering experiment from which we could learn things, like we learned, we had another proof of the fact that this effect of brightening clouds was actually true, but also if we're claiming that these did not have any real Attributable effect. Then that does tell us something about, well, there is a category of permitted experiment that can inform our climate, our modeling, and our knowledge but that is also, we can safely say, this does not have any long-term effects.”

“It might still, and it probably is still going to be better than not doing than letting the warming just keep unchecked.”
Visioni: IMO 2020 sulfur cuts added roughly 0.05°C of global warming
“There's a few course estimates that, just based on Earth's sensitivity, say, suggested, says probably Alf, a 10th of a degree overall of increased warming.”
Visioni: Halting all human emissions immediately would cause near-term global warming
“We know that if today, if tomorrow morning there were no more anthropogenic emission of anything at all in the world, The main impact that we would see in the first decade, it would be a warming, because this aerosol effect that is masking part of the warming …”
Visioni: Sulfate geoengineering ozone depletion would likely stay within 5%
“We, and based on what we've seen with previous volcanic corruptions, we know that the depletion of ozone wouldn't be catastrophic. It would probably be around plus or minus five percent of what it is now.”
