A star is a nearly perfect black
radiation emitter - absorber because it has an atomically uniform
surface composition and temperature. Earth is far from a black body
because it has a two phase atmosphere and highly nonuniform surface
composition and temperature. Every planet's night - day side is hugely
different from a black body.
Siddons also describes dynamic
effects. Heat transfer by conduction, convection and radiation across
Earth's solid and liquid surface and through its two phase atmosphere,
with a tremendous altitude pressure - temperature gradient, has very
complex low high (daily) and low (millennia) frequency dynamics. While
these are described by known physics equations (Navier-Stokes, Maxwell
etc) they are intractable, unsolvable and of little help.
I have read Gerlich and
with great admiration and respect. They say so.
Consider how one would use
Siddons graph to
calculate the "average" temperature of the Moon's entire surface with
no atmosphere. Accounting for topography, craters, faults and transient
shadows. Within 0.1C.
Control system engineering
practice is to
ensure mathematically the proposed system is well modeled, measurable,
observable and controllable before attempting to design it. Prior to
Kyoto 1997 I proved using anthropomorphic CO2 for Earth's thermostat is
inadequately modeled, unmeasurable, unobservable and uncontrollable. So
it won't work no matter what Kyoto, UN, Congress or G8 do. Setting
setpoints of control systems like thermostats always involves
optimizing a risky tradeoff, which I developed a procedure to solve.
The procedure in Waxman-Markey Cap and Trade won't work. Since no one
has ever built a thermostat for climate of an entire planet, it would
seem prudent for the designer to prove he know what he is doing, his
system will work and it will do no harm, before proposing it.
Particularly if he can't tell what good it will do and how much it will
cost. Particularly with benign, nonpolluting green plant food. And
particularly since some climate change is healthy and living creatures
have capability to adapt and evolve. Particularly when there is no
temperature or CO2 problem anyway.
And particularly when its leading

one has ever constructed a heat engine which does not
throw away in its exhaust a relatively large fraction of the heat
supplied to it, and it is safe to say that no one ever will. The
impossibility of constructing an engine which, with no other
outstanding changes, will convert a given amount of heat completely
into mechanical work is a fundamental law of Nature, known as the
second law of thermodynamics." (2,
1824 Sadi Carnot proved
the maximum theoretical frictionless reversible efficiency is E = Wo/Qi
= 1 - T2/T1, where Qi is total heat in, Wo is net work out, T2 is
temperature of surroundings (air, cooling water), K and T1 is
temperature of source (flame, steam), K. For example boiler efficiency
for max work extracted from 538C superheated steam to 20C cooling water
is 1 - 293/811 = 64%. Furnace efficiency for max work extracted from
coal combustion to flue gas is about 60%. Turbine generator for max power from shaft input work is
<80%. So max
theoretical combined cycle efficiency is about 0.64*0.60*0.80 = 31%.
Since 1824 engineers around the world have managed to get the actual
efficiency close to 30%. Engineers gave you energy efficiency already;
government won't create any more profitably.
Gore claims "if we just put our minds to it, we can
change all that" and overcome that evil second law. By the way the
first law of thermo is energy can be neither created not destroyed,
only transformed and conserved.

I can understand an incompetent

will finance your opponent in 2010. Everyone knows majority rules in
Congressional law making.
