A paper published today in Atmospheric Chemistry and Physics finds that clouds located in the stratosphere over the poles act to cool the stratosphere by adiabatic cooling, which is the cooling of air parcels as they rise and expand, rather than by ‘trapping heat’ below the clouds resulting in ‘radiative cooling’ of the stratosphere above.
This finding contradicts a tenet of AGW theory, which predicts that infrared radiation from greenhouse gases will ‘trap heat’ to create a ‘hot spot’ in the troposphere and cooling of the stratosphere. This study finds that cooling of the stratosphere is instead due to rising air parcels rather than a decrease in radiation due to heat ‘trapped by greenhouse gases’.
The findings of this study corroborate the climate theories of Chilingar, Jelbring, van Andel, and several others.



The data already contradict this tenet; the ‘hot spot’ is missing.

You are correct. This new paper addresses the mechanism(s) at work, i.e., the reasons why it is not only “missing,” but couldn’t be there in the first place.
