Atmospheric scientist Dr. Dan Visioni discusses climate model estimates of temperature increases caused by cleaner marine fuels unmasking warming.
Opinion
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: 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: Unintended shipping aerosol drop reveals safe threshold for geoengineering experiments
“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, befor…”
Assertion Not checkable as stated
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: 20 years will not be enough to scale CDR effectively
“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.”
Prediction Not checkable as stated
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.”
