> but there in indisputable proof of the basic method of action (CO2, CH4, H20 greenhouse effects) and we can measure that effect in the lab

Yes, and those measurements tell us that without a large amount of positive feedback, the effect of greenhouse gases alone is too small to worry about.

> and then correlated it to measured climate change that normalized for various known climate cycles

Nope, this has not been done. The climate models cannot reproduce the data at all with just the measured greenhouse effect of the various greenhouse gases. They have to dial in a large amount of positive feedback, and even then the only period of time for which they reproduce the data tolerably well is the latter half of the 20th century. The model outputs don't match the early 20th century warming, they don't match the mid 20th century cooling, and they don't match the early 21st century pause.

The correct, honest scientific conclusion from all of this is that the models are simply not good enough at this point, i.e., we don't understand how the climate works well enough at this point, to support multi-trillion dollar policy decisions.
