Start with the know fact that CO2 absorbs infrared in a logarithmic fashion, and end with the fact that if there were positive feedbacks in the Earth's climate system, we all already be fried, or frozen solid.
Computer models are not science they are the tools of charlatans.
Not always. Like any other tool, they can be misused.
“Computer models are not science they are the tools of charlatans.”
I’m in the business of computer modeling. Models can be extremely useful if properly designed and validated. The AGW guys have done very poorly in the validation phase. It’s almost as if they are uninterested in making predictions with their models and testing them against reality. They just want to make predictions. If they were in business, their customers would have fired them years ago.
