“Testing … testing … is this model powered up?” Willis Eschenbach guest posts on Anthony Watts’ website and mentions about Judith Curry’s “excellent blog”, where she has apparently been talking in her usual vague way about a subject that she seems to have only a superficial understanding of. In this case about “verifying and validating” climate models.
After drowning us in a deluge of Excel charts derived from a variety of old (6+ years) climate models and using a conveniently short 20-year span, Willis tells us that generalized climate models don’t mirror the specific fluctuations of real temperature trends well enough. This, somehow, is a surprise to Willis. Apparently all the climate models must be discarded now.
Newsflash: “general” is not “specific”. The impact of one-time events will never be predicted. Regardless, I guess we can’t trust any of them sneaky climate computer models, can we Anthony?
