climate modelers claim, why is the daily mean temperature in a dry, desert area warmer (in spite of nighttime cooling) than a humid tropical area at the same latitude?
On the one hand,
climate modeler claim that their model are adequate to base future decision on them.

The specific
claim made is that the number of grid boxes in actual

climate models will have much more uncertainty than the actual physical
climate, hardly something
modelers don't recognize.
Modelers may
claim that these feedbacks are not arbitrary because they must exist, otherwise real
climate would fuctuate madly.
Inasmuch as essentially all of the IPCC
claims of AGW attribution, the projections of future
climate changes and the resulting recommendations to policymakers are based on GCM simulations, this is a fairly damning conclusion that will not make many

For good measure he also throws in a conspiracy theory by
claiming that
climate modelers only want to scare people, because they wouldn't get money for their research otherwise.
What I find most fantastical about the zeal of the
climate modelers is how they will compose such contorted arguments to justify their
claim of a scientifically significant warming trend of about 1 degree C over the last century.
The IPCC and
climate modelers don't
claim otherwise.
