The only correction I see referenced was the amount of CO2 produced by people after the papers were written. Annual CO2 emissions from human industry is an input to the model, rather than the model itself, but it does affect the result and can only be estimated when the models were published. Seems pretty reasonable to me. Unless I overlooked other changes.
