As with many real-world modeling exercises, it's perhaps a fool's errand to attempt to capture the entire space of possibility, unless the pure notion of capturing the domain is what's interesting. In reality there are a number of practical constraints that place limits on the search space for these kinds of models, including ones that are likely genuinely decoupled from CO2 concentrations (think of things like mutation rates).
