Sure, you see "What we got" isn't acceptable with greenhouse theory as modeled, but that could mean numerous things. For example, water vapor is credited with 80-97% of the greenhouse effect, depending on who one listens to. But that occurs down lower in the atmosphere, often very close to the ground, and might well block ground emissions that would otherwise get to the higher layers when the CO2 effect is imagined.
Here, though, we are discussing the CO2 greenhouse effect, and whether it is a large or a small effect. From the "modeled hotspot" vs "actual no hotspot", we have to pretty much conclude that CO2 has a low effect. So I'm not saying there is no CO2 greenhouse effect, but just to peg a number on it, let's say 2xCO2 for climate sensitivity of 0.5C increase. I can reconcile this type of CO2 climate sensitivity with the "What we got" image.
Make sense?
