True, one such predicted effect was the hotspot in the upper tropical troposphere. It has not appeared and is now mostly buried in the memory hole. The climate models have changed in the meantime and the hotspot has mostly disappeared from the model output.
My entire point with that post was to point out that no known model has been able to even remotely reflect observations as far as “Climate Change” (AGW) is concerned, and that is a known fact for anyone who is paying attention, and it seems you are one of those paying attention.
Nonetheless, eventually mankind may be able to finally account for all of the variables that are needed to somewhat accurately reflect reality as far as predicting climate trends over the long term, and are fairly good with very short term (several days) at this time, but we are not at that level of intelligence at this time.
