The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 6 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
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…”
Visioni: Geoengineering research should rely on modeling over small-scale experiments
“When it comes to the kind of discussion that we need to be having right now, I am a bit skeptical about how much small-scale experiments could move the needle. Whereas, I think that once we're going to go to the point where we've sort of gotten enough people o…”
Visioni: Abruptly halting solar geoengineering immediately reverts planetary temperatures
“Once we were to do it for long, once we were to keep it up for a couple of years or more, and so we actually have that cooling, then yes, of course, interrupting the injection immediately would just bring us back to whatever temperatures we would have without …”
Visioni: Solar geoengineering cannot fully replicate a low-CO2 climate
“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,…”
Visioni: Smaller cloud droplets create brighter, more reflective clouds
“If you have more cloud nuclei, so particles that allow this coagulation, this condensation to happen, the more nuclei you have, the more this water vapor that condenses is distributed across more nuclei, and so you have smaller water droplets. And the optical …”
