The Scientific Method, as you are attempting to describe, relies on empirical evidence and the principle of falsifiability not climate models. I refer you to the truly outstanding lecture entitled Cargo Cult Science given by the inestimable Richard Feynman way back 1974. Without doubt if he were alive today he'd have a field day ripping climate pseudo-science apart.

Sorry Luddite, but computer
Modeling is now an integral part of all science. You should know this given you pose as a computer expert anonymously online. Stop lying in the name of purity.
