Oh yeah, I fully agree. I don't think any meaningful change is going to happen, in the US especially, until states start to collapse from climate crises anyway, so any actual positive geo-engineering probably wouldn't happen unless some kind of hypothetical post-collapse communist state has the ability to do it. I also won't be surprised if we just kick the can down the road with something like this eventually, and make the problem worse in the long term by acidifying the atmosphere for decades or centuries. I'd hope that an industrial communist state would fix it in the long term, but it's all hypotheticals from here anyway.
I try not to be a doomer as much as I can help it, but now truly is the time of monsters.
