The (missing) tropical hot spot « Climate Dialogue
so I can find it later. interesting discussion by three scientists in the field.
Mears of RSS makes a good case for Willis' theory, and the IRIS effect too.
Sherwood seems to want to 'just stop talking about it, already'
Christy decimates the models again
"The bottom line is that, while I have some ideas based on some evidence, I don’t know why models are so aggressive at warming the atmosphere over the last 34 years relative to the real world. The complete answer is probably different for each model. To answer that question would take a tremendous model evaluation program run by independent organizations that has yet to be formulated and funded.
What I can say from the standpoint of applying the scientific method to a robust response-feature of models, is that the average model result is inconsistent with the observed rate of change of tropical tropospheric temperature - inconsistent both in absolute magnitude and in vertical structure (Douglass and Christy 2013.) This indicates our ignorance of the climate system is still enormous and, as suggested by Stevens and Bony, this performance by the models indicates we need to go back to the basics. From this statement there is only a short distance to the next - the use of climate models in policy decisions is, in my view, not to be recommended at this time."
There is a reason I like John Christy and Roy Spencer.. They dont mince words.. They tell it like it is.
