I have recently read this paper. The central claim involves the 2nd
law of thermodynamics - that is heat flows from the warmer to the
cooler. It is claimed that the various Earth energy budgets are
incorrect because they involve energy flows from a cooler atmosphere
to a warmer surface. It is indeed the case that AGW theory (and it is
not the case that there is any comparison with a real greenhouse - but
this was always only a metaphor)involves increased radiation downwards
from the atmosphere. There is increased radiation from a warmer
molecule in the atmosphere in all directions - an exponential increase
to the 4th power in accordance with the Stefan-Boltzmann
relationship. But this does not imply a breach of the 2nd Law of
Thermodynamics unless there is a net flow of energy (and therefore
heat) from the cooler to the warmer. The latter does not apply in any
of the energy budgets.
Proving that that the atmosphere is not an actual greenhouse is
pointless and the claim of a voilation of the 2nd law is wrong.
The 1st law is the energy conservation law - energy cannot be created
or destroyed merely transformed. The basis of global energy balances
but not relevant here.
Apply you own criterion and don't take it on faith. There is
radiation from the surface to the atmosphere and back radiation from
the atmosphere down - but the net energy flow is upward from the
surface in all of the energy budgets (and in the models) as it must be
in accordance with the 2nd law.
It is wrong - but be assured that the responses here show a less than
than considered understanding of science as well.
