Chaos theory absolutely, unequivocally prevents such models from making detailed long-term predictions. But that doesn't mean the models are worthless; they can still make detailed short-term predictions and gross long-term predictions. Ed Lorenz was a weather modeler; he invented chaos theory to explain the long-term failure of his models. But weather models and climate models are nevertheless useful today if we're aware of their limitations.
