No. As in why a uniform level of heat energy, no matter how high,
cannot be used to extract mechanical motion.


In the global weather system there are NEVER uniform levels of heat,
because there are three primary shear forces exerted on the atmosphere
by planet rotation, there is polar and equator insolation differences,
there is season tilt., there are irrgularities of surface features,
there are irregularities in oceanic topography, there are different
albedos of surfaces.


Fine, but that was not the point. The point was a technical one about a
statement that was wrong *in and of itself*.


Even current levels of CO@ have effects and it is paramount to be
monitoring these effects to build the database crucial to accurate
predictions of the future.

You have been a denialist, and a "uniformist", and you have been
visibly wrong.


No. The problem now becomes, not whether a uniform temperature can be
converted to mechanical energy (winds, currents, etc ) but whether global
warming ( a change in the average temperature) will have an effect on the
levels of heat differences. It is not a simple question.
