Throwing Cold Water on Global Warming
All Atmospheric Gasses Absorb Solar Radiation
All atmospheric gasses absorb infrared radiation (IR), including Oxygen and Nitrogen (both gasses constituting greater than 99% of the atmosphere's gasses):
"Due to their symmetry, homonuclear diatomic molecules like N2 and O2 do not exhibit a static electric dipole moment, such as H2O, nor is there the possibility to induce vibrationally a dipole moment, as in the case of CO2. Thus, there are no strong infrared absorption bands due to dipole transitions as in the case of the major greenhouse gases. However, as discovered by Crawford et al. , collision-induced absorption leads to weak absorption features of N2 and O2 in the infrared [e.g., Hartmann et al., 2008]."
The peer reviewed paper affirms the non-negligible roles that Oxygen and Nitrogen play, in the aggregate, in heating the atmosphere*...
"This work challenges a common perception on the negligible role of O2 and N2 as natural greenhouse gases in the Earth’s atmosphere compared to species like CH4 or N2O. It is in fact the large abundance of oxygen and nitrogen which compensates for their only weak interaction with infrared radiation through collision-induced absorption bands."
Due to the atmospheric concentration of atmospheric N2 (O2) that is about 2000 (550) times higher than that of CO2 and about 4.4 X 105 (1.2 X 105) times more abundant than CH4, even the weak infrared absorption of N2 (O2) can become radiatively important.
Nitrogen molecule IR absorption bandwidth strength (3.8 to 5 microns). Nitrogen also absorbs ultraviolet radiation,
Oxygen molecule IR absorption bandwidth strengths (non-IR lines are at wavelengths
between 0.6 and 0.7- visible light, and at wavelength 1000.0 - microwaves)
Oxygen also absorbs ultraviolet radiation and gamma and x-rays
...contradicting the bold faced lies put out by politically co-opted climate scientists, where Oxygen and Nitrogen are said to absorb zero IR.
NASA, And 'Educational' Organizations, Lies In Vivid Black And White
"You have already learned that Earth's atmosphere is composed primarily of nitrogen and oxygen. These gases are transparent to incoming solar radiation. They are also transparent to outgoing infrared radiation, which means that they do not absorb or emit solar or infrared radiation."
"It has been understood since the 19th century that some gases absorb infrared radiation (IR) that is emitted by the planet, slowing the rate at which the planet can cool and warming the surface. These so-called greenhouse gases include carbon dioxide and water vapor, as well as ozone and methane among others. Note, however, that the bulk of the atmosphere is made up of nitrogen and oxygen molecules which don't absorb IR at all."
"Most of the gas in the atmosphere is nitrogen and oxygen – both of which are molecules made of two atoms. The atoms in these molecules are bound together tightly and unable to vibrate, so they cannot absorb heat [sic] and contribute to the greenhouse effect."
"Nitrogen and oxygen don’t absorb infrared energy in our atmosphere because their molecules – composed of two identical atoms – don’t vibrate or rotate at infrared frequencies."
"The presence of complicated molecules in the earth's atmosphere impedes the earth's ability to radiate thermal energy into space. By complicated molecules, I mean ones that have vibrations that allow them to absorb infrared light. The most abundant molecules in our atmosphere, nitrogen and oxygen, don't do that."
We now see that all gasses in the atmosphere absorb IR to varying degrees, not simply the 'greenhouse gasses' such as Carbon Dioxide or Methane. In fact, the term 'greenhouse gas' is a misnomer—all atmospheric gasses are 'greenhouse gasses'.
Why do institutions such as NASA lie regarding Nitrogen and Oxygen's ability to absorb IR? Because in learning the true IR absorption qualities of Nitrogen and Oxygen, those interested would be curious about Nitrogen and Oxygen and perform more research into those two molecules, learning that they are, in fact, warmer than Carbon Dioxide.
Carbon Dioxide Has Less Volume Than Either Nitrogen and Oxygen, Therefore Carbon Dioxide Is Cooler
More important than a gas' IR absorption capabilities is an atmosphere gas molecule's volume. One pound of Carbon Dioxide has a volume of 8.7 cubic feet, smaller than Nitrogen at 13.8 cubic feet, and Oxygen at 12.1 cubic feet. With a smaller volume than either Nitrogen and Oxygen, Carbon Dioxide can only possess less heat than Nitrogen and Oxygen.
Because the atmosphere is a Nitrogen-Oxygen based atmosphere, representing over 99.9% of the atmosphere's gasses, adding Carbon Dioxide to the atmosphere cools the Nitrogen-Oxygen based atmosphere, as demonstrated in experimental designs conducted by Professor Gert Venter, Agricultural Engineering, University of Pretoria: “You know, that’s why all I can do is laugh when these global warming monkeys tell me that CO2 is a greenhouse gas. It is not, and I have live, precise experimental situations in over 30 sites around the world that prove that it is not. These guys create a model in their computers, based on arbitrary assumptions, and then ignore all the experimental evidence to the contrary. My experiments show that INCREASING ATMOSPHERIC CO2 IS CORRELLATED WITH A DECREASE IN ATMOSPHERIC TEMPERATURE in my agricultural environments.”
With Carbon Dioxide A Cooling Molecule In Earth's Atmosphere, Then What Is Warming The Atmosphere?
The heat obtained by both Nitrogen and Oxygen comes from thermals and latent heat from the surface, heat from man-made structures on the ground, and the heat produced by incoming radiation absorbed directly by the atmosphere, not solely from the absorption of outgoing IR. The warmth that blankets us each day is due to Nitrogen and Oxygen, not the puny amounts of the trace gas Carbon Dioxide, nor any of the other trace gasses.
Regarding man-made structures on the ground, interestingly NASA's 'earth's energy budget' illustration fails to provide the data on the amount of solar radiation absorbed by those structures, and it is the massive growth of urban sprawl the last sixty years that accounts for the atmosphere's warming, a warming that is being tempered by increasing amounts of Carbon Dioxide in the atmosphere.
* The temperature on Venus, which is higher than on Mercury though Mercury is closer to the Sun, is due to the high atmospheric pressure on Venus and not the predominance of Carbon Dioxide in the atmosphere, which accounts for 96% of the planet’s atmospheric gases. The atmosphere on Venus has a mass 90 times that of Earth's (and Venus' equatorial circumference is 5% smaller than Earth's; Venus' equatorial circumference is 38,025 km, while Earth's is 40,030 km), producing an atmospheric pressure of 1300 psi. On Earth water boils (212 F) at 14.69 psi.
It should also be noted that the so-called greenhouse effect when applied to a planet's atmosphere is a canard. Unlike the enclosed environment of a greenhouse, where heat is trapped by the structure, a planet's heat is constantly escaping into space via convection.
