We don't need any climate models to know that Earth is warming. We can tell that just from what we know of: how electromagnetic radiation works, the basic thermodynamics of gases, determining isotope ratios of the carbon making up a sample of CO2, how much solar energy falls on the Earth, the mechanisms by which energy can leave the Earth, the amount of energy leaving Earth as measured by satellites.

That's enough to allow verifying that:

(1) a net heating of the Earth taking place,

(2) this is mostly caused by humans (mostly be emission of greenhouse gases from fossil fuels) (and yes, we can tell the difference because emissions from burning fossil fuels have a different carbon isotope ratio than other sources), and

(3) it is getting more extreme.

All you need climate models for is to try to figure out where the extra heat will end up and what it will do there.
