“Do the GCM’s only consider unproven positive feedback in the climate system without including any negative feedbacks.”
The GCMs include all known feedbacks. Not sure what you mean by “unprovem.” The WV feedback, as Richard notes, is well founded in theory and the models predicted the correct drying of the stratosphere after the Mt. Pinatubo eruption. so we have strong confidence that the models’ predictions for CO2 warming are good as well.
I have no idea what Richard is talking about with the WV feedback being negative because of aerosols. It doesn’t make sense. Perhaps he can point as to the paper he “published” in Nature that makes this assertion.
