Biological systems play a huge role in the climate too so its not purely physical simulation.

This is true, but there are no biological simulations in the mainstream models, just various correction factors with their own uncertainty. I wish they had biological data because then we would have more domains in which to measure their accuracy.

What none!?

This has been a long standing criticism of climate change models and I had expected it to be a major focus of research.
