Carbon Dioxide Not a Well Mixed Gas and Can’t Cause Global Warming

By: John O’Sullivan

One of the least challenged claims of global warming science is that carbon dioxide in the atmosphere is a “well-mixed gas.” A new scientific analysis not only debunks this assertion but also shows that standard climatology calculations, applicable only to temperature changes of the minor gas, carbon dioxide were fraudulently applied to the entire atmosphere to inflate alleged global temperature rises.

Acceptance of the “well-mixed gas” concept is a key requirement for those who choose to believe in the so-called greenhouse gas effect. A rising group of skeptic scientists have put the “well-mixed gas” hypothesis under the microscope and shown it contradicts not only satellite data by also measurements obtained in standard laboratory experiments.

Canadian climate scientist, Dr Tim Ball is a veteran critic of the “junk science” of the International Panel on Climate Change (IPCC) and no stranger to controversy.

Ball is prominent among the “Slayers” group of skeptics and has been forthright in denouncing the IPCC claims; “I think a major false assumption is that CO2 is evenly distributed regardless of its function.“

School Children Prove Carbon Dioxide is Heavier than Air

Dr. Ball and his colleagues appear to be winning converts with their hard-nosed re-examination of the standard myths of climate science and this latest issue is probably one of the easiest for non-scientists to comprehend.

Indeed, even high school children are taught the basic fact that gravity causes objects heavier than air to fall to the ground. And that is precisely what CO2 is – this miniscule trace gas (just a very tiny 0.04% of atmosphere) is heavy and is soon down and out as shown by a simple school lab experiment.

Or, we can look at it another way to make these technical Physics relationships easy. This is because scientists refer to ratios based on common standards.  Rather than refer to unit volumes and masses, scientists use the concept of Specific Gravity (SG).  Giving standard air a value of 1.0 then the measured SG of CO2 is 1.5 (considerably heavier).  [1.]

CO2: The Heavy Gas that Heats then Cools Faster!

The same principle is applied to heat transfer, the Specific Heat (SH) of air is 1.0 and the SH of CO2 is 0.8 (heats and cools faster).  Combining these properties allows for thermal mixing. Heavy CO2 warms faster and rises, as in a hot air balloon.  It then rapidly cools and falls.

This ‘thermal’ mixing is aided by wind flow patterns, but the ratios of gases in the atmosphere are never static or uniform anywhere on Earth.  Without these properties CO2 would fill every low area to dangerously high levels.  Not ‘high’ in a toxic sense, only that CO2 would displace enough Oxygen that you could not have proper respiration.  Nitrogen is 78% of the atmosphere and totally non-toxic, but if you continue to increase Nitrogen and reduce Oxygen the mixture becomes ‘unbreathable.’

It is only if we buy into the IPCC’s “well mixed gas” fallacy that climate extremists can then proceed to dupe us further with their next claim; that this so-called “well mixed” CO2 then acts as a “blanket” to “trap” the heat our planet receives from the sun.

The cornerstone of the IPCC claims since 1988 is that “trapped” CO2 adds heat because it is a direct consequence of another dubious and unscientific mechanism they call “back radiation.” In no law of science will you have read of the term “back radiation.” It is a speculative and unphysical concept and is the biggest lie woven into the falsity of what is widely known as the greenhouse gas effect.

Professor Nasif Nahle, a recent addition to the Slayers team, has proven that application of standard gas equations reveal that, if it were real, any “trapping” effect of the IPCC’s “back radiation” could last not a moment longer than a miniscule five milliseconds – that’s quicker than the blink of an eye to all you non-scientists. [2.]

Doomsaying Climatologist Abandons ‘Back Radiation’ Meme

Only recently did Professor Claes Johnson persuade long-time greenhouse gas effect believer Dr. Judith Curry to abandon this unscientific term. Curry now admits:

“Back radiation is a phrase, one that I don’t use myself, and it is not a word that is used in technical radiative transfer studies. Lets lose the back radiation terminology, we all agree on that.”

IPCC doomsayers claim it is under this “blanket” of CO2 (and other so-called greenhouse gases) that the energy absorbed by Earth’s surface from incoming sunlight gets trapped.

But one other important fact often glossed over is that CO2 comprises a tiny 0.4% of all the gases above our heads. Nasif Nahle reminds us that this is a crucial point when considering the claims of the “grandfather” of the greenhouse gas hypothesis (GHE), Svente Arrhenius.

Change in CO2 Temperature Is NOT Change in Atmospheric Temp

When applying the GHE formula devised by Arrhenius, IPCC scientists appear to have forgotten that we must consider the proportion of carbon dioxide in the atmosphere, not the proportion of the whole mixture of gases.

Even if Arrhenius was right about the GHE any change of temperature obtained from his formula is exclusively a change of temperature of the mass of carbon dioxide, not of the atmosphere.

The trick of climate doomsayers is that they draw their conclusions obtained from the Arrhenius formula for CO2 (only 0.04% of atmosphere), then apply that change of temperature to the WHOLE Earth; this is bad science, or possibly fraud.

Nahle poses this question for GHE believers:

“Is the atmosphere composed only of carbon dioxide? Why calculate the change of temperature of a mass of carbon dioxide and then after say it is the change of temperature of this trace gas that now becomes the temperature of the whole Earth?”

Astrophysicist and climate researcher, Joe Postma similarly comments:

“No one seems to have realized that any purported increase in temperature of CO2 due to CO2 absorption is APPLIED TO CO2, not the whole danged atmosphere! Again, just a slight tweak in comprehending the reality makes a whole paradigm of difference.”

NASA Data Confirms CO2 Not a Well Mixed Gas

Professor Nahle and his colleagues insist that in addition to the above facts the proven varying density of atmospheric CO2 also needs to be taken into account to show how IPCC scientists are guilty of the greatest scientific swindle ever perpetrated.

From the NASA graph below (verify with link here) we can discern distinct and measurable regional variations in CO2 ppmv. So even NASA data itself further puts paid to the bizarre notion that this benign trace gas is “well-mixed” around the globe.

NASA’s diagram thus not only proves CO2 isn’t a well mixed gas but also demonstrates that there is no link between regions of highest CO2 concentration and areas of highest human industrial emissions.

Groundbreaking Science Trumps IPCC Junk Claims

Both Postma and Nahle have recently published groundbreaking papers discrediting the GHE. Professor Nahle analyzed the thermal properties of carbon dioxide, exclusively, and found that 0.3 °C would be the change of temperature of CO2, also exclusively, not of the whole atmosphere. Nasif pointedly observes:

“Such change of temperature would not affect in absolute the whole mixture of gas because of the thermal diffusivity of carbon dioxide.”

Additionally, Nahle and his Slaying the Sky Dragon compadres demonstrate that carbon dioxide loses the energy it absorbs almost instantaneously, so there is no place for any kind of storage of thermal energy by carbon dioxide. To the more technically minded what Nahle and his colleagues say is that the release of a quantum/wave, at a different wavelength and frequency, lasts the time an excited electron takes to get back to its base state.

Thus the IPCC’s CO2 “sky blanket” is shot full of holes as rational folk are increasingly abandoning the unphysical nonsense that carbon dioxide “traps” heat and raises global temperatures. Policymakers may be the last to wise up but they, too, must nonetheless consign the man-made global warming sham to the trash can marked “junk science.”


[1.] In our “current environment,” atmospheric nitrogen and oxygen vastly outweigh CO2. Nitrogen: 3,888,899 Gigatons; Oxygen: 1,191,608 Gigatons; Carbon Dioxide: 3,051 Gigatons. On a weight basis the specific heat of nitrogen and oxygen together is approximately 1 per kilogram, whereas CO2’s is about 0.844. Thus it’s clear that everyday air has a better ability to hold onto heat.

Debunking the Greenhouse Gas Theory in Three Simple Steps

By: John O’Sullivan

A group of international scientists find that carbon dioxide is a coolant, the calculations in the greenhouse gas theory are wrong and humans are not killing the planet.

It may have taken the Climategate controversy to prompt a growing band of specialist scientists to come forward and work together to help climatologists get themselves out of an almighty mess. But at last we know for sure that the doomsaying equations behind the man-made global warming new research shows the numbers were fudged, the physics was misapplied and group thinking perpetuated gross errors.

Yes, the greenhouse effect has now been proven to be a fabrication. That mythical concept called ‘back radiation’ whereby heat was supposed to be recycled in the atmosphere and worsened by the dreaded burning of fossil fuels is contradicted. In reality it’s now been shown that the atmosphere acts like a coolant of Earth’s surface, which, otherwise, would have a temperature of 121 Degrees Celsius, or 394 Kelvin (K).

A team of dedicated international experts, known as the ‘Slayers,’ all highly qualified in their respective fields, spent the past year deliberating over the deep-rooted errors in the calculations employed in the greenhouse gas theory. Their findings are devastating to all those who claim carbon dioxide and the ‘greenhouse effect’ heats our atmosphere.

The standard argument of a clique of climatologists associated with the Intergovernmental Panel on Climate Change (IPCC) is as follows:

  • 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.

This is the so-called greenhouse effect (GHE) examined closely by a team of professors of physics, mathematics, astrophysics, chemistry and biology who joined forces to put the numbers under a fresh microscope.

This group of 20+ specialist scientists has given the infant (and generalist) science of climatology a much-need shake up. Indeed, the ‘Slayers’ say a monumental paradigm shift is now very much under way.

Below, in simplified form, we examine in three parts how their brilliant analysis has eviscerated one of the most costly and mistaken theories of modern science, man-made global warming.

Part One: Coolant Carbon Dioxide

In a recent ground breaking paper Professor Nasif Nahle proved that carbon dioxide (CO2) actually works as a coolant when it interacts with water vapor in the atmosphere to induce the air temperature to cool not a warm.

Physicist, Joe Postma, in this epic debunk further describes the correct application of the laws of thermodynamics to address how the thermal capacity (or conductivity) works with the ‘coolant’ CO2. As Postma tells us,

“Carbon dioxide and other atmospheric gases merely serve to make the atmosphere cooler in daytime, warmer at nighttime. This is what empirical evidence tells us. ”

He asks us to think of how this interpretation differs from what the uneducated and pseudo scientists say that is “the greenhouse effect makes the planet warmer than it should be.” But we know that in truth what we actually observe is somewhat entirely different.

In the future, says Joe, people will declare: “The atmosphere keeps the planet from getting too hot in the daytime, and too cold at night-time”.

Just that simple realization alone kills the so-called ‘blanket’ analogy of greenhouse gas theorists stone dead.

Step Two: How the IPCC Picked Wrong Numbers from the Get-go

Now we address the IPCC’s biggest mistake. They started off with a flawed number, and then have to invent lots of other unreal processes and mechanisms to make the real Earth’s average temperature coincide with their numbers.

Professor Nasif Nahle points out that error in IPCC models:

“It’s quite simple. The flux of power on the top of the atmosphere is 1368 W/m^2; however, they [IPCC] say it is 341 W/m^2.”

Without an atmosphere, the Earth would be receiving a flux of 1368 W/m^2 of solar power (394K under the zenith facing the Sun). With the atmosphere, it receives and absorbs 718 W/m^2 (335K) on its surface.

Postma, a recent addition to the team sums up how much getting those first numbers right matters:

“We all agree that the atmosphere has an “atmosphere effect.” But what is of interest to us is how this effect changes if the properties of the atmosphere changes (a little).”

In this excellent paper geologist, Timothy Casey, gives a calculation for how much temperature variation will be caused by changes in CO2. It tells us:

“If carbon dioxide produced the backradiation claimed by Arrhenius, thermal conductivity measurements of carbon dioxide would be so suppressed by the backradiation of heat conducted into this material, that the correspondingly steep temperature gradient would yield a negative thermal conductivity of carbon dioxide.”

What Casey shows is that in reality, a 10,000 ppm increase in carbon dioxide could, at most, reduce the conductivity of air by a measly one percent and given the actual difference between the thermal conductivities of carbon dioxide (0.0168) and zero grade air (0.0260), a 10,000 ppm increase in carbon dioxide would lower the thermal conductivity of zero grade air by 0.36 percent.

Casey finds,

“That would represent a 0.36 percent increase in thermal gradient, or a surface warming of 0.18 percent and a ceiling cooling of 0.18 percent of the total difference in temperature between the top and bottom of the affected air mass. In the case of a tropospheric carbon dioxide increase of 10,000 ppm, that would correspond to a warming of 0.125ºC, or one eighth of a degree Celsius at the earth’s surface.”

“However, even if this wasn’t a negligible enough effect, Casey finds the proverbial doubling of CO2 would only contribute a change of 0.0040C at the surface”.

Step Three: Exposing the Idiocy

Groupthink is ‘Step Three’ in our explanation of how climatology got itself into such a muddle. Here’s a perfect example of scientific idiocy displayed by someone who ought to know better. Postma shows how a reality disconnect by one such theorist makes a mockery of IPCC numbers when applied to the real world. He explains,

“Yesterday a professor tried to tell me that a blackbody (BB) would heat itself up if its radiation would shine back on it – if it was surrounded completely by a perfect mirror.

I told him that all that would happen is you’d get a standing electromagnetic wave between the BB and the mirror, with a frequency spectrum and flux density equal to that of the BB – there’d be no spontaneous increase of temperature.  50C is 50C and there’s no way to get more than 50C, from 50C.  The only way to get more than 50C is to bring in some outside work or something hotter than 50C.”

Postma then enlightened the perplexed professor that it’s impossible to make candles or insulation warm itself by its own radiation.  “If we could make a candle burn hotter by reflecting it’s light back onto it, that would have been discovered long ago.”

The Slayers thus ask us to put it all in terms of radiation and conduction being analogous modes of heat transfer.  Then it becomes plainly obvious and ridiculous.

Like his learned colleagues Postma suggests climatologists apply a little more common sense and joined up thinking; their heat transport equations should properly be addressed in terms of conduction such that radiation and conduction are simply MODES of heat transfer. If an object can heat itself via its own, or “colder” radiation, then it should also be able to heat itself by conducting with itself, or conducting with a cold body.

“An object conducting with itself to make itself hotter?  What the heck does that even mean?  An object conducting with a colder one and thereby becoming hotter?  I don’t think so,” insists Postma.

Thus when we start to accept that conduction and radiation are analogous modes of heat transfer, then it dawns on us all that the laws work the same way with both of them.

Therefore, by working through this ‘Three Step Greenhouse Effect Debunk’ we are left with only one conclusion: IPCC junk (generalist) science is well and truly busted by the specialists in their fields.
