These guys can’t predict the weather for tomorrow, and yet they know the future.
Where have you been? Weather prediction is incredibly accurate these days, due to global weather modeling. I recall a big February snow storm, I think two years ago, that was predicted four or five days in advance for Chicago, at a time when there was no such weather system in existence anywhere. They predicted it would form over western Texas, track north, gain strength, and hit smack dab on Chicago days later ... and it did, with the predicted snow amounts. Absolutely amazing.
The thing is, this has nothing to do with climate models. These are not based on weather models, and hence are problematical, as they are not actual dynamical models, the way the weather models are. This is an issue which interests me greatly, but I don't know much more about it! ... except that it was raised by the recently deceased what's-his-name, the French climate scientist who wrote a book on GW skepticism, which is naturally hard to find these days.
