There are probably good proxies for climate effects though: i.e. reductions in more measurable stuff, so I think the situation is no that analogous to AI. And some global health and development stuff involves things where the outcome we actually care about is hard to measure: i.e. Deworming and it’s possible positive effects on later earnings, and presumably well-being. We know deworming gets rid of worms, but the literature on the benefits of this is famously contentious.
