Under advisement, I have enabled the ignore member function to stop the hostility creeping into my replys.
Coming back to an earlier area of objection I raised, there is the matter of modeling complex systems in general. A feature of these complex systems is their sensitivity to initial conditions, that is to say that where one ends up depends on where one starts. So too with the climatology models, and the farther back in time one wants to start the model, the less information and therefore the more error, we have in the initial conditions used to start a run.
There is then of course that other sensitivity to conditions issue of complex systems referred to as the butterfly effect, which says essentially that small changes in an operating complex system can have large & unexpected effects. If one of the minimalized forcings happens to have some role in the climate operations akin to the butterfly's wings, then the model is at risk of inherent flaws.
That's awrap.
