Just pick one of your points that seems misunderstood: > In my time, the hockey-stick would be an indication there is something wrong with the model ( instability ). "Nature does not behave this way" But the popularly known "hockey stick" graph isn't a model prediction, it's a reconstruction of past and current temperatures. "Nature is currently behaving this way"... And as you point out, that's an indication that there's something wrong -- instability.
