Because it's just kicking the can down the road. This will cost Trillions which you might as well invest in a transition to clean energy now because you have to do it eventually anyway.

If the impact of climate chains looks like it's posing a risk to us as a species then perhaps blocking the sun temporarily is something that should be considered. Right now it sounds like there's still a chance that we could avoid the worst if we continue acting faster and faster. Pointing to a hypothetical sun shield decades in the future, now, is similar to pointing to practically unlimited CCS capacity sometime in the future just so we don't have to do anything drastic now.

pure fantasy that the world will ultimately do the "might as well" there though. The world is moving on but we're running out of time to prevent things that are a lot worse than having to deal with acid rain and simply keep pushing sulhpur into the atmosphere and then slowly taper off the sulphur.

where are you getting trillions from? this paper estimates it at 10b.
