"Are you aware that the computer models are all wrong?"

All models are wrong, but some are useful. The fact of the matter is that Global Climate Models (GCM's) are based on known physics and chemistry (see my original comment about infrared homing missiles). Given a change in these physical and chemical parameters nature will always respond the same way. CO2 will always absorb infrared, you can't argue with the physical chemistry which we knew about 200 years ago. These laws are baked into GCM's, in fact it's why we know they're so reliable, they only answer to the laws of nature. 

What's really spooky though, James Hansen's 1988 GCM predictions are actually right on the money.
