I would also advocate for the mixture of both plans.
One more reason for it is that they work on different timescale. Cutting emission and removing CO2 on current level of technologies would takes decades to have an impact on climate. But geo-engineering has reaction time around 1 year so we could use it to cover bumps on the road.
Such covering will be especially important if we consider the fact that even if we completely stop emissions, we could also stop global dimming from coal burning which would result in 3 C jump. Stopping emissions may result in temperature jump and we need protection system in this case.
Anyway we need to survive until stronger technologies. Using nanotech or genetic engineering we could solve worming problem with smaller efforts. But we have to survive until with date.
It looks for me that cutting emissions is overhyped and solar management is "underhyped" in public opinion and funding. And by changing with misbalance we could get more common good.
Actually, some of the geoengineering has been tried/studied, the acid in atmo, and the ocean dumped iron.
The iron addition worked quite well, quadrupling the sea catch of fish, and creating a bloom of aquatic algae and plankton. If we can dump in a priming of shell creating plankton, along with the iron, you can pull down quite a bit of ocean CO2, and send it to sea bottom. I think they have only published one sci paper on it, but a couple other papers on econ gains were put out before they raided and arrested the folks that carried it out. The Canandian n...
