Reality Leaves A Lot To The Imagination | Watts Up With That?: "The analysis by Hansen et al. (2005), as well as other recent studies (see, e.g., the reviews by Ramaswamy et al. 2001; Kopp et al. 2()05b; Lean et al. 2005; Loeb and Manalo-Smith 2005; Lohmann and Feichter 2005; Pilewskie et al. 2005; Bates et al. 2006; Penner et al. 2006), indicates that the current uncertainties in the TSI and aerosol forcings are so large that they preclude meaningful climate model evaluation by comparison with observed global temperature change. These uncertainties must be reduced significantly for uncertainty in climate sensitivity to be adequately constrained (Schwartz 2004)."
“Preclude meaningful climate model evaluation” … hmmm. Of course, they don’t make that admission all the time. They only say things like that when they want to get money for a new satellite. The rest of the time, they claim that their models are accurate to the nearest 0.15°C …
COTD UPDATE: Time for a very fine Feynman quote from the comments:

fred;
A simpler way of saying what you iterate above is: Climate Models illustrate the opinions of the experts and programmers who wrote them.
Time for Feynman: “Science is belief in the ignorance of experts.”
Heh.
