In my post on "Runaway Global Warming", I pointed out that the radiational energy balance as claimed by the IPCC and most climate scientists exhibits an unrealistically large infrared radiation emitted by the Earth's surface, and an almost equally large "backradiation", supposedly emitted downward by the "greenhouse gases", especially carbon dioxide. In this way, they insist, the 0.04% of the atmosphere that is carbon dioxide controls the temperature of the globe, by returning heat to the surface that would otherwise quickly escape to space. To a competent physicist, this should set off alarm bells, primarily because in their model, the energy coming off the surface is greater than that coming from the Sun, which is simply impossible.
I would like to add a note to show how the infrared radiation actually works in the atmosphere, and that there can be no large "backradiation" from CO2 or other infrared-absorbing gases, because that is directly counter to the way the atmospheric radiation really works in the process of distributing heat energy in the air.
There is a new book out, exposing the overwhelming weakness in the climate consensus of a "greenhouse effect" responsible for global warming, titled "Slaying the Sky Dragon: Death of the Greenhouse Theory." I have posted a comment on one of its web pages, an updated version of which I present here:
In our gravitationally bound ocean of air, heat always rises, and the infrared radiation (supposedly "trapped" or "slowed down" by CO2, in the "greenhouse" theory) is just another pathway for the heat to go. It is, in fact, not a continuous path, since it depends on the temperature at which it was radiated and the temperature of any molecule it hits. The IR radiation given off at any given temperature level (height) of the atmosphere, cannot (statistically, or macroscopically, speaking) be absorbed by molecules immediately below, because they are too warm to be excited by the "cooler" radiation from above, and will quickly bounce it back upwards. The molecules immediately (or within a short distance) above the level from which the radiation was emitted, can absorb it, and it is quickly transformed into additional kinetic energy of those molecules, which are then convected upward, like the common candle flame, which is stretched upward by the same effect. Thus, there can be no real, large "backradiation", because it is heat radiation, and heat must rise naturally, like the candle flame (congratulations to the book's author, for pointing out this clear example of natural heat flow in the air). Why this is not obvious to the bulk of climate scientists is an ongoing sordid tale, and one of monumental proportions (although it is just one small example of the overall incompetence in science today, which only my discovery of the world design of the "gods" has revealed).
The temperature profile of the atmosphere is basically determined only by gravity, which increases the pressure in the atmosphere the farther down toward the Earth's surface you go (just like the pressure increases with depth in the water ocean), and the greater the pressure, the greater the temperature -- the presence of infrared radiation, or infrared-absorbing gases, has essentially nothing to do with it.
How long will it take to purge climate science of its belief in the "greenhouse effect", and how long to disabuse recent generations of students (and the general public) of the bad science which they have been, and continue to be, so determinedly indoctrinated in?
