“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 would be the first one to go away.”

Visioni: Solar geoengineering is probably better than unchecked warming
“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: 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.”

Visioni: Rogue geoengineering planes could simply be shot down
“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.”
