Dr. Denis Rancourt's "Most downloaded free-access scientific article about planetary warming physics" has been extensively commented upon and critiqued by Prof. Dr. Raymond Pierrehumbert (Louis Block Professor, Department of the Geophysical Sciences, The University of Chicago), arguably the leading establishment expert on such physics models.
The complete email exchange was initiated by an email from Rancourt to the scientists at Real Climate and is posted HERE. Further replies will be posted as comments to the present blogpost (below).
Rancourt's January 8, 2012 email concludes:
"You are a recognized establishment-science expert in these simple models. You have not identified any errors in my model. I think you will agree that when a simple model contains no physics errors and no calculation errors and obtains correct results without over stretching (without seeking results that the model is not structurally able to legitimately obtain), then if you wish to argue that the model needs more complexity the onus is on you to demonstrate that the added complexity is required rather than being superfluous."
