Expected CO2 increases would modify the Earth's albedo by 0.4%. Clouds modify it by > 25%. We can't predict clouds more than five days in advance, under our well-studied present climate conditions. It is difficult to see why climate modelers are confident they can predict average cloud cover in the future when different climate conditions are in effect.
