Why, And How, We Are Cooling Down
Hmm... there is no "Green House Effect" -

New Insights on the Physical Nature of the Atmospheric Greenhouse Effect Deduced from an Empirical Planetary Temperature Model

From the paper:

Quote:A key entailment from the model is that the atmospheric ‘greenhouse effect’ currently viewed as a radiative phenomenon is in fact an adiabatic (pressure-induced) thermal enhancement analogous to compression heating and independent of atmospheric composition. Consequently, the global down-welling long-wave flux presently assumed to drive Earth’s surface warming appears to be a product of the air temperature set by solar heating and atmospheric pressure. In other words, the so-called ‘greenhouse back radiation’ is globally a result of the atmospheric thermal effect rather than a cause for it.
I know you think you understand what you thought I said,
but I'm not sure you realize that what you heard is not what I meant!
Radiative Equilibrium or Radiative Poppycock?

by Alan Siddons, August 2008

"What animates global warming concerns is an imaginary law of physics called "radiative
equilibrium". Energy out must equal energy in, this “law” says. Which does sound plausible on
the face of it. In this view, however, if the light emitted by a heated object is suppressed in some
way, its radiant energy will increase past the level of radiant input until it breaks through the
barrier... in obedience to this “law”.This notion originates from a long-ago misconception about how glass greenhouses work, thus the family name this "effect" goes by. It was believed that glass blocked the passage of "dark radiation" (infrared) and kept storing energetic photons inside it. Once those photons had accumulated enough power to overcome the glass barrier, radiative equilibrium was achieved.So this is the scenario: sunlight enters, heat is generated and dark light is emitted. This dark light is amplified because of the blockage and finally exits at the same magnitude as the entering sunlight. But only after the light "trapped" inside has raised the greenhouse's temperature. Since the barrier will keep raising the temperature until the barrier is broken, increasing the barrier's strength will get you any amount of internal heat you want. (If only that were true...)It is 19th century poppycock. And here’s a telltale sign of it: Why do you always see a "layer of greenhouse gases" depicted overhead in illustrations about the “greenhouse effect”, when in fact these molecules are at their densest concentration right at your feet?
