Uh, they don't need to predict what happened three days ago. Because what happened three days ago isn't a "prediction".[/.quote]
A simulation that can not accurately rebuild the past when the parameters are known isn't worth the disk space it took to write it. If it can't rebuild the past when the data are known, it certainly can not be expected to represent the future with any degree of certainty.
The reason simulations can not rebuild the past is because the parameters upon which they are built don't reflect real world physics. They are built on the premise that CO2 is a greenhouse gas capable of absorbing and retaining heat when in reality, CO2 nor any other greenhouse gas other than water vapor can do such a thing.
