While the ineffable Albert Gore, posing in front of a row of American flags, yesterday advanced the modest proposal that Americans should “move beyond partisan divisions,” and agree to be forced by government to abandon the use of every form of fossil fuel, simply abandoning trillions of dollars of corporate and private infrastructure, and spending even more on brand new windmills and hamster wheels, an outbreak of heresy was discovered within the most prestigious circles of the scientific community itself.

The American Physical Society’s Forum on Physics & Society the same day announced its intention of conducting a debate on Anthropogenic Global Warming, and went so far as to allege the existence of substantial dissent from orthodoxy within the scientific community.

There is a considerable presence within the scientific community of people who do not agree with the IPCC conclusion that anthropogenic CO2 emissions are very probably likely to be primarily responsible for the global warming that has occurred since the Industrial Revolution. Since the correctness or fallacy of that conclusion has immense implications for public policy and for the future of the biosphere, we thought it appropriate to present a debate within the pages of P&S concerning that conclusion.

The APS governing board was clearly not happy that one of the Physical Society’s internal units has the effrontery to conduct a debate upon the factual basis of a conclusive political position adopted by the same board last November. The APS web-site is pointedly proclaiming its certainty that mankind was at fault all over again.

The American Physical Society reaffirms the following position on climate change, adopted by its governing body, the APS Council, on November 18, 2007:

“Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth’s climate.”

So there.

It appears that it was Daily Tech’s posting proclaiming that The American Physical Society, an organization representing nearly 50,000 physicists, has reversed its stance on climate change, under a headline stating Myth of Consensus Explodes that provoked the APS governing board’s denial of a change of stance.

ABSTRACT

The atmospheric greenhouse effect, an idea that 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. According 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 scientific 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 greenhouse effects, (b) there are no calculations to determine an average surface temperature of a planet, (c) the frequently mentioned difference of 33 degrees Celsius 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.

The Earth is not a greenhouse. As the authors observe:

It is not the “trapped” infrared radiation, which explains the warming phenomenon in a real greenhouse, but it is the suppression of air cooling.

CONCLUSIONS:

A statistical analysis, no matter how sophisticated it is, heavily relies on underlying models and if the latter are plainly wrong then the analysis leads to nothing. One cannot detect and attribute something that does not exist for reason of principle like the CO2 greenhouse effect. There are so many unsolved and unsolvable problems in non-linearity and the climatologists believe to beat them all by working with crude approximations leading to unphysical results that have been corrected afterwards by mystic methods, flux control in the past, obscure ensemble averages over different climate institutes today, by excluding accidental global cooling results by hand, continuing the greenhouse inspired global climatologic tradition of physically meaningless averages and physically meaningless applications of mathematical statistics.

In conclusion, the derivation of statements on the CO2 induced anthropogenic global warming out of the computer simulations lies outside any science. ...

The point discussed here was to answer the question, whether the supposed atmospheric effect has a physical basis. This is not the case. In summary, there is no atmospheric greenhouse effect, in particular CO2-greenhouse effect, in theoretical physics and engineering thermodynamics. Thus it is illegitimate to deduce predictions which provide a consulting solution for economics and intergovernmental policy.

*E8 encapsulates the symmetries of a geometric object that is 57-dimensional and is itself 248-dimensional.

Abstract: All fields of the standard model and gravity are unified as an E8 principal bundle connection. A non-compact real form of the E8 Lie algebra has G2 and F4 subalgebras which break down to strong su(3), electroweak su(2) x u(1), gravitational so(3,1), the frame-Higgs, and three generations of fermions related by triality. The interactions and dynamics of these 1-form and Grassmann valued parts of an E8 superconnection are described by the curvature and action over a four dimensional base manifold.

Lisi makes for a wonderful news subject, being a perfect California type, a surfing and rock-climbing ultra-bohemian, the sort of person found dancing around the fire at the annual Burning Man Festival. His theory has a wonderful appeal based upon its simplicity (no pun intended) and elegance, but we will have to wait to see whether it is confirmable by testable predictions.

The Telegraph article quotes some scientists who regard Lisi’s theory as “a long shot,” but there is general agreement already on how interesting and elegant it is. However all this comes out, my own (testable) prediction is that A. Garrett Lisi will be receiving some very good offers of academic appointments at major universities.
