Yipes: Warmist Mike MacCracken fails again to convince me that the science is settled

Q&A On Two Climate Science Questions – A Contribution By Mike MacCracken | Climate Science: Roger Pielke Sr.

I defer to the IPCC analyses (AR4 and pending AR5) on the growing, but limited capabilities of the global models to project (they do not “predict” as my comment on your note in Climatic Change attempted to clarify several years ago–so you should know better than to be saying “predict”) the present and future changes in the statistics of various Earth system oscillations (and what, in some cases, our limited observational record suggests, perhaps incorrectly, may be oscillations). I would only note that I don’t consider this limitation to accurately simulate the current statistics of Earth system oscillations to mean that the models are not reasonably projecting how the mean state of the global climate is likely to change over periods of several decades and more due to combustion of fossil fuels, but do think this limitation makes it more difficult to project the combined changes of fossil fuel combustion and land cover change on regional scales.
