Interesting. I remember that Michael Mann wrote a Scientific American article about 1999, telling us to expect 0.5C warming when we eliminate the sulfates. We knew it would happen, and it's happening. Maybe it's not so shocking.
Does anyone know how much sulfates still come from coal plants? Back in 1999 that was the big source, I think. This could be an argument to pursue climate restoration, restoring CO2 below 300 ppm, to cool the planet. Peter On Tue, Mar 1, 2022 at 5:39 PM Ron Baiman <[email protected]> wrote: > Thanks Peter.
