The Glove Doesn't Fit

Fortunately,
there is a method that can be used to check on whether the
observed warming is anthropogenic. 
It relies on comparing the observed pattern of warming
with the one calculated from GH models. 
Essentially we try to see if the “fingerprints”
match.  The
fingerprint is the pattern of warming, that is, the rate of
warming at different latitudes and altitudes. 
Greenhouse warming should give increasing rates as one
goes from the surface up into the atmosphere -- peaking at
about 10 kilometers, where the rate of increase is about a
factor of two greater than the surface rate, and quite
pronounced in all the models. 


The
observed pattern, however, does not show any increase at all;
in fact, the data from balloon-borne radiosondes show a slight
decrease over the equator. 
Evidently, the observed and calculated fingerprints
don’t match, indicating that the human contribution to
current warming is insignificant, too small to be discerned.
