New Unphysical AGW Simulator Available!

Attention warmists, the latest version 2.07 of the University of Colorado "Greenhouse Effect" java simulator is now available! It provides an animation you can control to find out the exact temperature from adding "lots" of "greenhouse" gases causing unphysical back radiation in violation of the 1st and 2nd laws of thermodynamics. "Lots" of back radiating greenhouse gases will add enough work input to raise the global temperatures 7°C! Plus don't miss the second tab at the top to show that "greenhouse" gases are just like a pane of glass or even 3 panes! (please ignore RW Wood's classic 1909 paper which ripped to shreds the Arrhenius "glass pane" paper).

Radiochemist Alan Siddons alerted me to this simulator and writes, "not only does it falsely attribute radiative forcing to the IR-opacity of glass, but it also (and by necessity) shows less IR escaping from the earth as the greenhouse effect progresses. In fact, greenhouse theory asserts that the SAME amount of IR escapes as the greenhouse effect progresses. Consequently, more photons would have to appear out of nowhere in order to simultaneously hold photons in and also release them. Somehow the University of Colorado couldn't simulate that miracle". He also provided this IPCC diagram with his added notations to help clarify this phenomenon:

Most ridiculous AGW study of the week

Press release 7/2/10: "Previous studies have shown that reducing carbon dioxide emissions to zero would not lead to appreciable cooling, because carbon dioxide already within the atmosphere would continue to trap heat. For cooling to occur, greenhouse gas concentrations would need to be reduced. “We wanted to see what the response would be if carbon dioxide were actively removed from the atmosphere,” says study coauthor Ken Caldeira of Carnegie’s Department of Global Ecology. “Our study is the first to look at how much carbon dioxide you would need to remove and for how long to keep atmospheric carbon dioxide concentrations low."



The Carnegie simulations of "scrubbing the atmosphere" of deadly CO2 (using technology that doesn't exist) shows that for every 100 billion tons of CO2 removed from the atmosphere, average global temperatures would drop a whopping 0.16° C (0.28° F). And "further simulations showed that in order to keep carbon dioxide at low levels, the [imaginary] process of extracting carbon dioxide from the air would have to continue for many decades, and perhaps centuries, after emissions were halted."

Global CO2 emissions are 32 billion tons/yr

Thus, for the fictitious payback of 0.16°C of global cooling, all CO2 emissions would need to come to a complete halt and unknown technology developed to remove the .0389% CO2 content in the atmosphere at a rate more than double the current global emissions, for "perhaps centuries".



Let's get to work on that right away



{And we'll need to make sure the huge, unknown, global CO2 scrubbing technology can run off of solar power since otherwise it'll probably emit more CO2 than it scrubs.}

Why Greenhouse Theory Violates the 2nd Law of Thermodynamics

Greenhouse gas theory manages to not only violate the 1st law of thermodynamics, but the 2nd law as well. There are many ways of stating the second law of thermodynamics, such as "In a system, a process that occurs will tend to increase the total entropy". But Rudolf Clausius provided the simplest formulation of the second law:

"Heat generally cannot spontaneously flow [i.e. the net vector] from a material at lower temperature to a material at higher temperature."

or

“Heat doesn’t flow from cold to hot (without work input)”

Note how this diagram from NASA of the second law of thermodynamics (without work input) illustrates the net flow of heat as a one-way vector always from hot to cold:



Work input is required to cause any heat to flow from cold to hot, which is obviously true from everyday experience. For example in a refrigerator, heat flows from cold to hot, but only when aided by an external agent (i.e. the compressor). Note that from the mathematical definition of entropy, a process in which heat flows from cold to hot has decreasing entropy. This can happen in a non-isolated system if entropy is created elsewhere, such that the total entropy is constant or increasing, as required by the second law. For example, the electrical energy going into a refrigerator is converted to heat and goes out the back, representing a net increase in entropy.



Another way of stating the Clausius formulation of relevance to the AGW debate is

"energy from the hotter body has left that body - it therefore cools down. The smaller amount of energy from the cooler body cannot fully replace that lost energy; it just slows the rate of cooling."

Since "greenhouse" gases cannot add any energy to the system, or "work input", and are colder than the surface of the earth, they cannot cause additional warming of the earth; they just slow the rate of cooling. Furthermore, the "sunshade" or cooling effect of "greenhouse" gases outweighs the heating effect (due to absorption of incoming solar energy) by a factor of 100.







UPDATE: Alan Siddons (who is not the author of the above post) has just forwarded his reply to those questioning violation of the 2nd law of thermodynamics:





Key statement: The notion that colder matter does not radiate towards hotter matter defies common sense and causality.





I always see that weasel word: Toward. No doubt a cooler object does radiate "toward" a warmer object. The question is what happens as a result.



Say you have a blackbody plate (think of an electric heater) radiating 1000 W/m² toward another plate which, because of distance, absorbs half of that intensity, i.e., 500 W/m². At equilibrium, the receiving plate thus radiates 250 W/m² toward the 1000 W/m² plate. Question: Does the 1000 W/m² plate thereby rise to 1250 W/m²? If so, then, by raising the radiator’s temperature without adding more energy, you’ve disproved the first law of thermodynamics. Effectively, you’ve made the radiator heat itself. Moreover, now at 1250 W/m², the radiator will heat the other plate still more, absorb another dose of back-radiated energy, and will reach 1562 W/m². And so on, ad infinitum.





Either radiative heat transfer obeys the 2nd Law or it does not. If the 2nd Law does hold, then light can only transfer energy to something that is radiating less. This would mean that the physics of radiative forcing is fictitious.
