The fact that AGW is real does stand up to peer review, overwhelmingly. Im not sure where you get the idea it has to be repeatable. The evolution of human beings over millions of years is a fact, but it is not repeatable in a lab.

BTW, the fact of AGW does not rely on models. It relies on observation more than anything.

Models are only used for forecasts and climate scientists would be the first to tell you that the models are far from perfect.

Also, what is the average Global temperature SUPPOSED to be? Before you can tell me I have a fever, you have to first know what my temp is supposed to be under normal conditions. So what is it for Earth? tThe Earth has spent much more time at 22degC than at 12degC. Is 22degC the "normal" temp for the Earth?
Your question is nonsensical, and i answered it in the other thread. There is not an absolute temp for the earth. There is however a narrow range of temperatures under which life as we know it can survive.
