You might want to look up the law of unintended consequences.
The bigger the intervention, the bigger the potential unintended consequence.
By far the easiest solution to climate change is not emitting greenhouse gasses in the first place. It is still a monumental challenge but if we don't do that, we're just treating the symptoms not the cause
Some of us witnessed just how amazingly elastic our ecosystems can be just by the improvement in indicators like air quality due to reductions in human activity during covid. Human impact, while catastrophic, can revert amazingly quickly with radical behavioral change. Just something I try to keep in mind. I agree, that is the best path.
Aside of changing abiotic factors we're rapidly losing biodiversity. Not only species but genetic variation in populations. If a species has little genetic variety it has less capacity to survive extreme events as a whole. I wanted to point that out just in case someone comes to the conclusion that you can just bounce back all willy nilly from a shrunken population.
Except that has already failed. We already have sent enough CO₂ into the atmosphere that global warming is already here. You can no longer solve the problem by just stopping greenhouse gas emissions. All serious solutions now involve some form of geoengineering. Either block out the sun or pull CO₂ out of the air, those are the only possible options.
