Or, put another way, we're waaaay past "we can stop every bad thing from happening" point, but we're still in the "we can stop even more bad things from happening" range, and we won't be out of that range anytime soon - at least I hope so, I don't want to imagine what it would be like "Everything that can go wrong has already gone wrong so there's no point worrying any more."
"stop digging" should be our primary priority, but not at the expense of other solutions which can also be pursued in parallel.
Should have been from the start. There are so many climate change variables outside of human control (sunspots, volcanic eruptions, etc...) that it's better to just be prepared.
The issue is that investing in decarbonization, etc., is both a superior long-term strategy AND it makes all of the mitigation strategies you mention more effective bc the primary effects are not as bad.
Things like desalination where we aren't disturbing the system is fine. Cloud seeding on the other hand I wouldn't be so comfortable with widespread adoption.
