Title was “Are GCMs obsolete?” which is a bit jargon (GCM is general circulation model, used for climate modelling) and a bit clickbait - as with any headline question, can basically be answered “no”.

But I think the article is quite good - short overview of numerical modelling of the climate and discussion of future directions, both towards throwing more compute (ever higher resolution) at the problem, and improving models (emulators) at higher levels of abstraction to explore more scenarios, sensitivities, specific questions.
