Even worse than that, 2/3 of the past warming which is probably exaggerated by 2x (see Watts et al recent paper) is also supposedly due to water vapor feedback. Thus the models are supposedly "validated" using temperatures biased by urban warming. Not to mention there is no good record of deeper ocean temperatures needed to calculate heat storage.
The climate modelers do not model weather, they assume certain types of weather and input it using parameters. An assumption of constant relative humidity with increasing temperature is especially bogus since weather proves that wrong in many places every day. The models do not have a shred of a hope of predicting temperature regardless of the assumptions built into them.
Science is observable, measurable and testable. They Warmists have designed their “science” around violating all three.
