Paul Hamer sends me an email about Khilyuk and Chilingar: (my emphasis)
I had a quick poke around on the ISI database to see if anyone had cited
their original study that you’ve covered. I found that their is a single
citation – a self citation. It turns out Khilyuk and Chilingar have written
another article with the help of one O. G Sorokhtin.I can’t be 100% certain but seems like they’re making a very dodgy claim
here:“The main factor determining climate’s temperature parameters is the
atmospheric pressure.”They then proceed to breeze over geological history and suggest two
mechanisms that changed atmospheric pressure and hence the climate.From my reading of the actual paper they seem to suggest that pressure
relates to climate via the atmospheres heat capacity. They use the Stefan
Boltzmann equation to derive an equation for their basic model but they
completely fail to include any kind of greenhouse gas induced warming, natural or otherwise. They dismiss the
warming effects of greenhouse gases with the flimsiest of arguments:“According to the greenhouse effect theory, the low concentrations of
greenhouse gases for all practical purposes do not affect the tropospheric
air temperature, because after the greenhouse gases absorb the IR (heat)
radiation, the radiation disappears. Its energy is transferred into the
energy of oscillations of air molecule. As a result, the irradiated air is
heated, expands and rapidly rises to the stratosphere. There, it commingles
with the thinned air and the air temperature in the troposphere declines
again to the adiabatic distribution level, i.e., practically, it does not
change.”
Why don’t they consider re-emission of IR from greenhouse gases back to the
surface? Why don’t they consider re-distribution of internal energy into
translational motion via collisions? These are some fairly fundamental
processes.But, there’s much more:
“A similar situation must occur when the air is heated upon condensation of
water vapor. On the other hand, when the greenhouse gas concentration is
substantial, the opposite scenario occurs: there is climate cooling rather
than warming. If the nitrogen-oxygen Earth’s atmosphere was replaced by
carbon dioxide atmosphere (at the same near-surface atmospheric pressure of
1 atm), then [using Eq. (4)], the average tropospheric temperature would
have declined by several degrees instead of increasing as is generally
believed. This can be explained as follows: The adiabatic exponent for a
carbon dioxide atmosphere CO2 = 0.1428, which is lower than for the
nitrogen-oxygen atmosphere (N2+O2 = 0.1905). Molar weight of carbon
dioxide, on the other hand, is higher: (µCO2 = 44) than that for the
nitrogen-oxygen atmosphere (µN2+O2 = 28.89). Consequently, the carbon
dioxide atmosphere, like a thin blanket with lower specific heat, preserves
heat less than the thicker nitrogen-oxygen atmosphere with higher specific
heat.and my favourite piece:
“Likewise, if the carbon dioxide atmosphere on Venus was replaced by a
nitrogen-oxygen one at the same atmospheric pressure of 90.9 atm, the
surface temperature would rise from the current 735 K to 777 K (463C to
504C). Thus, increasing saturation of atmosphere with carbon dioxide
(despite its heat radiation absorbing capacity), with all other conditions
being equal, results in a decrease and not an increase of the greenhouse
effect and a decrease in the average temperature of planet’s troposphere.”“In conclusion, a common perception of climate warming as a result of CO2
and other “greenhouse” gases accumulating in the atmosphere is a myth. In
reality, CO2 accumulation, under the same conditions, can only lead to the
cooling-down of climate (also see Khilyuk and Chilingar, 2003).”I’m really shocked that something like this could have gotten past peer
review. So let me get this straight, if you ignore some fundamental laws of
physics and some basic mechanisms of the atmosphere you too can create a
simple model that proves just about anything you want. This work is a
perfect example of how to subvert the scientific method.
This is a Jan 2007 publication, so it hasn’t been cited yet by CO2science, Benny Peiser, Christopher Monckton etc etc. But I’m sure it will be.
