I'm not so sure. People who run the world DGAF about Kiribati or whatever. Rather, they really like mysterious and complicated schemes for transferring resources to themselves. E.g., all of USA's stupid wars. Also e.g. delayed availability in USA of covid antigen testing. Or also e.g., "carbon capture". "Every crisis is an opportunity."
Just look at the BS they excrete whenever they're forced to address albedo modification at all. [0] "Albedo modification is cheaper and actually possible, but if we do it rather than this much more expensive and totally ineffective thing then we'll have to keep doing it until we can figure out how to emit less carbon, which will never happen so just give us all the money while the world cooks." I'm paraphrasing but that's just because they don't want to publish anything so explicitly embarrassing to humanity.
If you're New Orleans, time to give up on being a city. Start preventing new construction. Incentivize people to leave.
Things like that really if we're going to get honest with ourselves about where things are headed.
