Yedvab: Stardust lab tests show its particle is highly chemically inert
“Lab tests that we've done show that our particle is, I'd say, at a very high level of inertness, but definitely better than any other alternative that it was provided so far.”
Yedvab: Background stratospheric levels make small-scale sulfate testing impossible
“One of the problems with sulfates, apart from what we've been discussing, is the fact that you cannot do testing at small scale of sulfates. And the reason for this, since this is something sometimes people overlook, is the very high background that you have c…”
Yedvab: Stardust particles match sulfate cooling effectiveness within tens of percent
“Our article, to be very, very straightforward, is not much better than sulfate with respect to the effectiveness and not much worse than sulfate.
So up to, I'd say,
A few tens of percents, which is not a, it's kind of similar.”
Visioni: Mount Pinatubo injected 10 to 20 megatons of stratospheric sulfate
“Pinatubo happened in 1991. It released anywhere between 10 and 20 teragrams. That's megatons. So that's a million of tons of sulfate in the stratosphere. We called that a big number, but it just released it once, and it had an effect for a couple of years, and…”
