climate models are tweaked to give results that look similar to actual past data, using simplistic methods that do not match what happens in reality. mother nature produces corrections that overshoot, large ones that counter the disrurption, smaller one in the other direction, then smaller one in the first direction, etc. models dont. the models simply dont use the same homeostatic methods that reality does. they dont replicate cloud systems, they need ocean currents as inputs rather than predict them, and every model uses 'aerosols' as a method to tweak the result rather than just a measured input.
