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…
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 ?

Well, hopefully we have some time to practice first. Because we're the only person in the room and the patient is bleeding out.
You are the doctor and the patient at the same time. On what body do you want to practice ?
Cold acidic oceans, or warm sulphur free ones?
The enthusiasm with geoengineering among the HN community is worrisome. Not sure which computing analogy would drive home the complete recklessness of this mentality but the Earth is not something you can reboot to the last working state once you harebrained patch implodes. It is true that we have been slowly geoengineering for ages (initially unwittingly, recently with eyes wide open) and it is also true that our mo…
There is no alternative. We have "aggravated the situation" (as you put it) beyond recovery. Doing nothing will now surely lead to an unacceptable outcome. We are going to have to fix it, or resign ourselves to a huge shrinking of the habitable region of the planet, with the hunger/famine/war that will accompany that. Obviously we can always make things worse. But when doing nothing is unacceptable, we have to start…
Up until the point climate change is becoming an existential threat, which it isn't yet, we shouldn't go doing anything too drastic. There is plenty of evidence that we can still avert the worst of it without resorting to geoengineering.

There are people saying we should not just not stop, but even increase sulfur injection: https://en.wikipedia.org/wiki/Stratospheric_aerosol_injectio... The thing is, this is not a one time solution. We would have to do it continuously, or else the temperature would quickly rise again. And we would have to increase sulphur injection if the CO2 level keeps rising. It could be a temporary solution though, e.g. until al…
We do this until CO2 levels come down. Hopefully 20-30 years. Regardless this is really a series of crazy experiments we are proposing doing on a very complicated system.

I don’t know. My province in Canada is experiencing anomalous weather events year after year, and while things still look “okay” we seem to be encroaching on visible threshold events quite rapidly. Sure, these events could mysteriously stop. Or stay very much the same, acting like a new normal that isn’t so destructive as to be an emergency. But the trend line is there. Fires increasing, biodiversity decreasing, floo…
Fires are actually decreasing. https://www.wsj.com/amp/articles/climate-change-hasnt-set-th... https://archive.li/WfDJh
Really? Of course they would say that.

The Earth's greatest temperature was before humans ever existed

Probably akin to "testing in production". But, as is in computing, it's still done all the time despite the dangers.
