You're right that it's not at all a quick fix, and that it requires a lot of energy. But it is the only sustainable solution: if we want to restore a preindustrial climate we're going to have to put the fossil fuel emissions back where they came from. So we're going to need a lot of surplus energy to do it, and it will take a long time. Which means that we need to start the R&D now, scale it up when we have surplus sustainable energy, and plan for the time it will take to execute. Concurrently, we need to push through the sustainable energy transition as fast as possible, and probably also figure out how to reduce solar heating of Earth while we do carbon removal over the next century or so. Welcome to the Anthropocene :)

I wonder if there is any point to go to a preindustrial climate though. By the time we get technology to the massive scale required to actually fix it, the worst effects will have already occurred. The climate will have already changed and we will have dealt with it one way or another. Going back at that point will basically mean another climate change. One that will be mainly for the better but will again have impact on nature that will have adjusted in the mean time. It won't be a 100% positive. I wonder if that is really worthwhile. And if things will really get back to what they were; For one the arctic ice, would that build up again in the exact same places? They have a large effect on jetstreams so I'm not sure if things would really go back to the same way things were in pre-industrial times. Also, in pre-industrial (and early industrial) times winters were really harsh sometimes. It wasn't all rosy either. I think around the 70s/80s the climate was the mildest though I didn't study it.
