I'm not sure what you are getting at. A model is essentially an unproven hypothesis, it can never be proven and confidence in the model depends on the evidence. With models on the effects of climate change (aka impact models) the confidence is pretty much non existent, there were literal studies done to show that, it's actually a huge and complex ongoing research area. So the predictions of doom is nothing more, but propaganda, that conveniently forgets to say that such predictions are very likely to be wrong.
