In a podcast with Russ Roberts, Kerry Emanuel says,
there is a huge difference between climate modeling and economic modeling. We know the equations. You guys don’t. Okay? And we actually know the equations we are trying to solve. And the problems come with actually trying to solve them. And arguably our computers aren’t nearly powerful enough to really solve them exactly; and they won’t be for generations, unless there is some unbelievable breakthrough in computation.
I am surprised that he received no pushback on this point. I confess that I paused there and searched the transcript for “water vapor” or “clouds.” Not finding either, I just skimmed the rest of the transcript without reading it closely.
