That's the thing about "models".

Some models are based upon proven concepts, such as the Black–Scholes option pricing model. You run it on computers so 
that you can spot inefficiencies in the market and trade on them before other people can.

Other models are where you try discover new concepts. You program in the data and what you know already, then program 
in a hypothesis to see if it gets the right result.

That is the evidence for "manmade" global warming. Instead doing experiments in the real world, they run experiments 
with their computer models. It's why us skeptics don't like global warming: it's "New Science" rather than old 
"Science".
