What I find interesting about the entire email corpus is the focus on the minutia of the statistics and the different proxies. In none of the emails from the core team members do we see any physics of radiation. It seems that if it were your role to “prove” the positive feedback of CO2 you would want to actually do some physics of radiative and convective transfer of energy in the atmosphere. This is where the rubber meets the road.
It seems that the entire consensus group have taken an assumption (positive feedback of CO2 increase) and are going deeper and deeper into the details of the proxies in order to show what the results of their assumption are.
I think that this is why as a discipline, more and more physicists are dismissing AGW.
