Yeah you have to literally stick your head in the sand to deny what's happening. The models are shit. They suck, and yet the degree to which they are more accurate than not should be enough to convince you.

The CO2 hypothesis was made in the 50s, long before there was conclusive evidence, and yet we are right on the predicted trajectory.

That CO2 emissions will cause warming was predicted first by Arrhenius Svante in 1896. While accurate modelling of all effects may be difficult, the basic effect follows from fundamental physics. There is really no excuse for doubting this.

The basic ideas go back even further than that. Eunice Newton Foote's "Circumstances Affecting the Heat of the Sun's Rays" was published in 1856.
