Marc Morano,

Alan Siddons makes sense. Bob Armstrong is ok too. You want a little physics? http://climatedepot.com/

A star is a nearly perfect black body 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 thermal 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 Tscheuschner(1) 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 designer proponent, at Oxford University on July 7, 2009 in Gore's 6min video. decried the 70% energy in coal "wasted" for generating electric power and called for "global governance" and massive government funded research to break the second law of thermodynamics embodied by the Sadi Carnot cycle since 1824. I took thermo in sophomore physics (2) at VaTech fall 1958; thermo in junior mechanical engineering (3) at VaTech in spring 1961 and thermo in graduate chemical engineering (4) at Purdue in 1964. Al Gore dropped out of Vanderbilt University Divinity School in 1972.

"No 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, p 342).

In 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.

And 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.

If you find a congressman reacting to those two little paragraphs with "I didn't take advanced math" tell him a) this is third grade arithmetic, b) if he cannot follow my 9 sentences, he cannot follow the 1428 pages of HR 2454 between 0300 and 1915 edt on Friday 26Jun09 and c) he has no business voting on $4 trillion budgets.

I can understand an incompetent or corrupt congressman would find this Pelosi argument persuasive: Trust me on this one. I remember loyalty. If you vote against Waxman-Markey, DNC will finance your opponent in 2010. Everyone knows majority rules in Congressional law making.

But I know the second law of thermodynamics rules renewable energy, Gore, Congress, Earth and the universe, since the big bang 13.7 billion years ago. Even if the polls say Gore is right. Gore is proud he won the popular vote in 2000; I say that reflects poorly on the majority of voters in 2000.

Gore wants billions for research to eliminate "energy waste". Ask physicist Chu, Secretary of DoE, if he is willing to accept $1 billion/year to do research to repeal the second law of thermo and develop a perpetual motion machine of the second kind. Ask him the return USA got for the millions spent by DoE since 1960 on Illinois, Pennsylvania and W Virginia coal combustion chemistry research.

Now Chicken Little is alarmed that Africa's soil doesn't contain as much carbon as N America soil. Its "degraded". And dirt has more carbon than air! Imagine that! Did he hear about high school chemistry calcium carbonate, sodium carbonate, potassium carbonate?

Con-artists trained in governance take a non problem and create one by scaring ignorant people! Now all we need is a perpetual motion machine. Lets offer $5 billion in grants to US universities and see if there are any takers.

I never imagined I would be writing such things obvious to most high school graduates in 1960: sunshine warms Earth, flora convert it and CO2 to carbohydrates and O2, which fauna combust with carbohydrates to make CO2 and heat. Climate changes. Very good.

I worked on NASA Apollo Command and Lunar Module digital autopilots and trajectory controls in 1967-69, before James Hansen did. They worked 40 years ago. I have built hundreds of successful thermostats.
