Ol' Daveboy is one ignorant ass, and determined to stay that way. Absolutely never seen an intelligent post from him. Skooker does better. At least some of the girls in his posts are good looking.
We use computer models for chemical reactions, engineering, aircraft design, weather forecasting, and so many other things. That ignoramouses like Daveboy want to go back to slide rules is simply a reflection of his inability to deal with modern devices. In fact, so much of the 'Conservatives' whining is do to their own deficiences in dealing with good change.
The difference is those are modelling far smaller systems, with far more detailed input data, a smaller time frame, and often can be directly compared to the system they are trying to reproduce. They are not trying to model a 2-3 billion year old climate system using 30 years of data (in this case).
Models are tools, and as tools can be used correctly, or misused negligently (or maliciously).
No one is running climate models for 2-3 billion years. Perhaps a hundred, tops.
The system they are modelling is 2-3 billion years old, assuming you discount the time the atmosphere was much hotter, and less oxygen-rich and most of the crust had not cooled.
