But climate science uses models as a large part of their argument that there is man made global warming.
FWIW, I worked for the USGS modelling ground water flow for 3 years. I took graduate courses in computer modelling (and did an NBA simulation for an A+ in one of those). What I really learned is models are a load of crap.
There's a thing called Chaos that breaks your models every time except for the simplest of things (baseball isn't so simple). That's why I also pointed out why they're crap - ARod could get hit by a bus. He could go on a hot streak and hit .500 the rest of the season, and no model would predict that. The govt. budget is a model, but they always seem to go over (Chaos strikes again). The Fed uses a model to model the economy and doesn't get it right - they're always reacting to why their model broke down and trying for "soft landings."
The model I roughly started for baseball could be refined and refined and refined. I tried to illustrate that by adding refinements (like accounting for the pitching). Every refinement costs more computing power. You might do that fist 1000 AB simulation in .1 seconds on a modern desktop. Doing the average of BA and BAA 10000 times might take 3 seconds. The more refinements, the closer you are to needing a super computer to run your model, which is where some of the more sophisticated models are at these days.
But there isn't enough super computer to model something with convincing results. To truly model baseball, you would need to model the weather, and for every microsecond of each at bat. You'd have to model the dust that might blow into the eye of the batter in a small gust of wind. You'd have to model the bacteria on that steak ARod had for dinner the night before (maybe he got a belly ache affecting his performance).
You seem to think you can't learn anything from Google.
Screw that.

I don't google to learn what I need to know for some message board debate. I google to provide support for something I am speaking from authority on.
Oddly, if you read the above linked page, they sound an awful lot like I do (about the baseball model).
