Tropical troposphere: not warming




Excerpt:
The three complicated colorful lines are the temperature data for the tropical troposphere - where the warming should be most rapid - according to RSS MSU, UAH MSU, and CRU: they seem to almost fully agree with each other. In terms of words, there has been no warming over there since 1980.

The thick, light blue line is the approximate average theoretical prediction by the garden-variety greenhouse models. Note that the IPCC predicts a warming of nearly 3 °C per century on the surface which should mean almost 5 °C for the hot spot in the tropical troposphere.

Actually, most reports that I have seen show that warming would be most extreme at the poles. I think a graph showing extreme temperatures at the poles would be much more illustrative.
