Read Hansen's book sometime. There's plenty of direct geological evidence that puts a pretty good bound on climate sensitivity, without depending on computer models at all.

This is because the climate has gone through major changes before, and we can see how much of an initial push it took, and what happened afterwards.

I'll check it out, but the second portion of your comment seems questionable.

Trending to a local minimum or maximum in modeling can be caused by small changes at certain points dependent on time and be completely negligible at other points. Without understanding the model: 1. We can't even pretend to understand causality 2. We can't infer the complex state at an individual time or even the magnitude of a push.
