New peer-reviewed paper finds the ‘hot spot’ predicted by climate models doesn’t exist — Published in Geophysical Research Letters
Study 'finds, once again, that climate models get the core assumptions wrong and that the fabled 'hot spot' is still missing. All climate models predict the tropical troposphere will warm the fastest to produce a 'hot spot,' yet observations from satellites and 28 million weather balloons confirm that there is no hot spot, and that the surface has warmed more than the tropical troposphere. This new paper confirms that the "The modeled [tropical tropospheric] trend is significantly higher than that of the measured ones, confirming that the vertical amplification of warming is exaggerated in models."
The authors “suggest that the vertical amplification of warming derived from modelled simulations is weighted with a persistent signal, which should be removed in order to achieve better agreement with observations.” Most likely, that “persistent signal” that “should be removed&quo t; from the models is the core assumption of an anthropogenic ‘hot spot’ present in all climate models.
