otherwise, it's just another hypothesis that executes on a computer. Validation is an essential step for any model to show that it accurately represents the system being modeled. It really isn't all that difficult - you start at a given point in the past where the initial conditions ar known and see how well the model reflects what actually happened in regards to climate change. If it can't do that, then how can anyone believe it can predict the future?
