There have been arguments that the sulfur dioxide we have been pumping into the atmosphere from ships has actually been geoengineering keeping temperatures down for decades.

But this might actually be bad news, because if we ever stop something like this, it could cause temperatures to rise extremely rapidly.

Sulphur Dioxide becomes Sulphuric acid when it breaks down in the atmosphere, the threat/reality of acid rain due to this is why sulphur scrubbers were mandated on power stations from the 1980s onwards.

Relying on it as it is at a specific snapshot in time would require a very precarious balance and is probably not worth trying to achieve, there are better geoengineering hopefuls.

Yeah, the thread mentions all of this - and definitely doesn't say we should keep doing this, its core takeaway is that it points to the possibility of things to do.

Oh for sure I don't think anyone is advocating we dump more sulphur dioxide into the air, but it's just an example of something that may have been globally slightly beneficial without us realizing

> I don't think anyone is advocating we dump more sulphur dioxide into the air,

People most definitely are advocating that...
