I can’t remember who (maybe he’s quoted further in the thread than I quickly scrolled) but there’s a scientist who has been talking about this on Twitter for a long time (when I used to use it). Pretty scary these things can happen, but he was warning basically we are further along with global heating than we thought and this pollution was just masking some of the effect in the Northern Hemsiphere of CO2 we’d already released. We were always going to have to stop sulfur emissions, might have just been better perhaps to have a bit more gradual phase out to soften the shock…
