On the Concept of Trying to Reduce a Complex and Nonlinear System (i.e., the Atmosphere) Into a Computer Model in Which Only a Couple of Variables Are Seen as Pertinent

It's an absurdity and a primary reason why people such as Judith Curry (climatology professor at Georgia Tech), David Evans (former climate modeler for the Australian government and an electrical engineer), William Happer (physics professor at Princeton), and even James Lovelock (one of the biggest global warming alarmists ever) have decided to take yet another look at this thing (global warming).......That, and the fact that the models were way, WAY, off.
