There is other evidence of changes. But the evidence connecting climate change to CO2 is purely these models. If there's so much evidence, surely you can find evidence for this connection that isn't circulation model? Code quality is extremely relevant. These models are nearly untestable. Climate is too chaotic and these models don't predict anything successfully on short timescales, and some of them don't predict anything on large timescale either - look up the term "flux adjustment". So at this point the entire trust in these and the entire narrative comes from a code that any experienced programmer with physics knowledge would never put the faith of the world economy on. Do you know what's even worse than not stopping a human made climate change? Destroying the world economy just to find out that it did not solve anything and still end up with worse climate but without economic power to deal with it. Somewhat similar to coronavirus lockdowns.
