To echo other posters, in most cases the predictions underestimated the impact - sometimes significantly so.

This makes sense when you think about it. Most climate reports that are requested are for disinformation campaigns, so the entity paying for them REALLY* wants it to say there’s no problem or the problem has been exaggerated, putting financial pressure on the researcher publishing the report to fudge the numbers or massage the implications.

(* Impartial climate reports aren’t needed in the private sector as the science is settled and the reality is not in dispute).
