I use prediction models (not climate ones) all the time. If you can’t give a model accurate data to start with, then the output is not accurate. Sounds oblivious doesn’t it? Well, the AGW fools think that they can use crude estimates for only a few of the many inputs required for climate prediction and expect to get an accurate output.

It seems clear to me that they know the answers they want and have built models to give them those answers and allow them to claim that the answers are “scientific” data.
