It is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence. -W.K. Clifford
Let’s limber up with some charts:

Nature at work. The climate changes. Stop it if you think you can!

The other, major “greenhouse gas” is water vapor and it has very similar radiative properties to CO2. CO2 is a pollutant. (My advice to medical researchers right now is to look into the availability of government grants to study “the ill-effects of second-hand carbon dioxide”.)

I liked this chart of temperature versus time so much, I decided to run it again, but from a different source, rotated 90 degrees and with atmospheric CO2 figured in.
This explains why it feels so cold right now, yeah?
There’s been a little uptick in CO2 lately. Can you see it right at the end of the chart there? Right-hand side. See it?
The Second Law of Thermodynamics
The simplest statement of the Second Law of Thermodynamics is the heat formulation, due to Rudolf Clausius:
“Heat generally cannot flow spontaneously from a material at lower temperature to a material at higher temperature.”
That is to say that, “heat doesn’t flow from cold to hot (without work input)”.
But, to paraphrase the IPCC description of the atmospheric greenhouse effect:
- A warm body (the earth) radiates heat to a cool body (the atmosphere)
- The cool body “back-radiates” (IPCC term) heat to the warm body.
- This process continues perpetually, with heat flowing round and round in a continuous cycle.
- The result of this perpetual process is that the warm body becomes warmer.
What is most amazing is that both alarmists and skeptic scientists have taken the above blatant 2nd Law of Thermodynamics violation at face value for so long. Many will shout that all bodies radiate — yes they do but NET heat flow is always from hot bodies to cool bodies (without the input of work), not the reverse. Note also that the 2nd Law does not care about the wavelength of radiant heat.
Now, I don’t know about you, but this “atmospheric greenhouse effect” suddenly smells a lot like deep physics doo-doo.
But according to the rules of whom to believe and whom to consult, the climatologists are fire-walled from those nasty physicists with the ugly German accents. And that’s too bad because this global warming thing, as the climate guys would have it, suddenly smells like some kind of perpetual motion machine. Alchemy.
So, what do the real physicists think? Well, here’s a paper by Gerlich & Tscheuschner, published in March 2009 in the International Journal of Physics, (sorry about that wisecrack about accents, guys) and they are pretty blunt, which is about what you’d expect from Germans.
Here’s the abstract from their paper, Falsification Of The Atmospheric CO2 Greenhouse Effects Within The Frame Of Physics:
The atmospheric greenhouse effect, an idea that many authors trace back to the
traditional works of Fourier (1824), Tyndall (1861), and Arrhenius (1896), and which
is still supported in global climatology, essentially describes a fictitious mechanism, in
which a planetary atmosphere acts as a heat pump driven by an environment that is
radiatively interacting with but radiatively equilibrated to the atmospheric system. Ac-
cording to the second law of thermodynamics such a planetary machine can never exist.
Nevertheless, in almost all texts of global climatology and in a widespread secondary
literature it is taken for granted that such mechanism is real and stands on a firm sci-
entific foundation. In this paper the popular conjecture is analyzed and the underlying
physical principles are clarified. By showing that (a) there are no common physical laws
between the warming phenomenon in glass houses and the fictitious atmospheric green-
house effects, (b) there are no calculations to determine an average surface temperature
of a planet, (c) the frequently mentioned difference of 33 °C is a meaningless number
calculated wrongly, (d) the formulas of cavity radiation are used inappropriately, (e) the
assumption of a radiative balance is unphysical, (f) thermal conductivity and friction
must not be set to zero, the atmospheric greenhouse conjecture is falsified.
I’ve said it before — I am a layman (with nevertheless a very good grounding in the scientific method) — but I foolhardily read the paper (skipping the math). It’s worth at least skimming.
The most shocking thing is this: the Physics department has thought for some time that the common glasshouse works simply by preventing convection. The paper describes some simple experiments you can perform yourself to satisfy yourself of the same. The effects of radiation are insignificant.
Bluntly, they claim there is no such thing as an “atmospheric greenhouse effect”.
Guess the climatologists didn’t get the email…
I am going to end with a statement that just entered my in-tray this evening; a statement by Thomas Chase, professor and climate modeler at the University of Colorado, talking about the CRU emails:
“However, because I teach and do climate research at the University of Colorado, I do assume all my e-mails are the property of the Colorado State Government and if necessary could be examined in depth by the appropriate officials. I am confident that there would be no e-mails, even if “taken out of context,” which would indicate (as the Climatic Research Unit e-mails do) that I was trying to rig the peer review process or trying to keep contrary information out of international summary documents. But these are relatively minor issues.
The real challenge to all scientists is to actively challenge the validity of their conclusions by seeking and supporting independent reproduction of their results. This is the foundation of science: intellectual self-criticism. The single biggest scandal revealed in the emails from the Climatic Research Unit is the lengths they went to refuse outside requests to make data and methodology available over the course of years including discussions about resisting Freedom of Information Act requests. Something like this would never show up in my e-mails. I have always enthusiastically aided anyone trying to reproduce or refute my results.
That the work produced by the Climatic Research Unit is not completely and independently reproducible because the data and methods were actively hidden from public scrutiny indicates that whatever was occurring over time at the Climatic Research Unit, it was never related to science.“
I am going to end with a photo taken this week, which has nothing to do with anything, unless it is perhaps as a harbinger of the awesome might of Nature.

Have a nice day.
