Obviously, any model can become unrealistic. That doesn't mean that
you can't get good information out of models, merely that you have to
be careful. The IPCC is being pretty careful.

Careful? As in the case of the hockeystick curve?

The hockey-stick data wasn't a model, but rather the ineptly-filtered
presentation of raw data. Mann certainly screwed up, because he didn't
understand exactly how his filtering procedure worked. Even there, the
peer-reviewing process finally worked and his curves were eventually
discredited.

Modelling is a lot harder to get right, and I'd expect the modellers
to be a lot more careful about testing their models and the referees
to be a lot demanding about the quality and thoroughness of the
testing.

Which isn't to say that the process can't ever go wrong - but the
IPCC's remit is to review all the peer-reviewed work on the earth's
climate, and they are going to notice if some published modelling work
disagrees with the rest.
