Why do we only hear about reducing CO2 and almost nothing on geo engineering?

Well there is discussion about it, but one approach is dealing with the root of the problem, and the other is more like slapping a band aid on after the damage is done. So which is better?

most of it isnt feasible in large enough instances to make a difference
i mean space mirrors?
really?

I think the best method of action is to run a closed circuit that uses excess energy for hydrolyses. Solar, wind, geo, nuclear all eventually make their way back to a fuel cell that generates hydrogen and stores it. It's less efficient than batteries but more utilitarian at this point, it's relatively easy to retrofit vehicles with hydrogen-hybrid systems which with proper tuning and R&D could substantially boost fuel efficiency. That's not just ICEs either, you could implement it in coal plants and natural gas plants too. Unfortunately the efficiency of reciprocity is really low, like below 13% and with current materials and understanding unscalable but it's excess energy so is efficiency really an issue?

Because every study on it has found that it's probably going to be far more expensive and risky than just not digging up the carbon in the first place.
Carbon sequestration is already a solved problem - it was done for us millions of years ago. We just need to stop un-doing it.

There is a fear that woud lead to not dealing with the root of the problem.
Kind of like leaning over the cliff edge, barely avoiding falling down by holding on to a long counter-weight, and not having any previous experience how well it would work.
We probably wil have to use it though, the CO2 ppm is raising too fast
Geo engineering will buy us a few extra decades, that's all. Not a permanent solution.

I don't know, which is better?

only if we call it that.

Large numbers of people dying usually counts.
