X's threads make even less sense now unless you think everyone you want to reach is on X. Also, just what a dumb name.

I will continue calling them Twitter threads, since the domain is still twitter[dot]com.

Not a bad thread but misses a critical point.

If the Sulfur emissions policies were known for >5 years and discussed for >10 years why aren’t they part of mainstream climate models?

The best answer I could find was essentially that models use a proxy for aerosols and so including the new policy might cause “double counting” of this forcing. This ‘conservatism’ caused this effect to be left out of the models.

So the story is basically that current mainstream models underestimated warming due to them ignoring this effect. But if they are missing this forcing, what other “insignificant” forcings are missing? Are they positive or negative? Are there other observations that don’t match the models?

This has really shaken my faith in the climate science community. I’m starting to think ClimateGate wasn’t the nothingburger the media made it out to be.

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…

Sorry if it's a naive question but if it was actually helping the situation, why do we need to stop?

So it seems the sulfur was removed for the obvious season that it's not good for respiratory health, but it may be a necessary evil for sometime ?
