[[A Question. How confident are you all that the Stefan Boltzmann constant is a suitable measure of W/m2 for an atmosphere?]]

So many people never 'get' that gases in Earth's atmosphere don't emit Planck black body radiation, thus aren't subject to the S-B Law. Planck radiation is only emitted by solids and liquids with surfaces, which explains the units of W/m^2. If gases did it, the units would be W/m^3. Yes, if gases are subjected to high temperatures and pressure that strip electrons from molecules, it becomes a dense plasma like on the Sun, and it does emit Planck radiation.

"The dominant source of black body radiation are transient oscillating dipoles induced by thermal vibrations within the material.

"If we treat a solid as a cloud of electrons intermingled with a cloud of nuclei, then any thermally induced vibrations will cause small local changes in the average electron and nucleus density, and this will result in a small local electric dipole. As these dipoles change with time they emit the electromagnetic radiation that we see as black body radiation.

"This applies to any system dense enough to support these sorts of charge density oscillations. Under normal conditions this means a solid or a liquid, but a plasma will behave in the same way if it can be made dense enough. This is hard to do in the laboratory but the Sun manages it :-)

"However a gas cannot sustain oscillations of this form because the gas molecules spend most of their time distant from each other. To a first approximation gases do not emit black body radiation. You only see radiation from rotational, vibrational and electronic transitions, and these produce discrete lines. Gas molecules do interact when they collide, so if you increase the number of collisions by making the gas denser and hotter it will start to produce more black body radiation and eventually transition to radiation dominated by the black body spectrum." -

Learn real thermal physics and how it defeats every IPCC lie. The IPCC lie machine turns thermal physics upside-down, inside-out, and ass-backwards to turn cooling processes into warming ones.

DON'T FOLLOW PRINCIPIA SCIENTIFIC! KNOWINGLY PUSHES CRACKPOT SCIENCE AND SUPPRESSES THE TRUTH How Air Pressure & the Water Cycle Affect Our Climate

**I posted this reply, only to find out that my main historyscoper gmail account was blocked but not my AOl account, but it was marked hold for moderation. They then suppressed this reply, which is the last straw as they continue to publicizing the ravings of crackpot Herb Rose and block the truth about him, proving they have no respect for scientific truth but are a crackpot rag not worth following. They never supported my program to teach New Real Climate Science, preferring this crackpot. Therefore I'm banning it, and hope everybody does. - TLW

My reply:

Ordinarily I skip posts by this Herb Rose crackpot, but this time it was at the top so I inadvertently read it.

[[Both the thermometer and the barometer are wrong. The barometer say the weight of the air per unit of area in a warm air mass is greater than the weight per unit area in a cold denser air mass. How can fewer molecules weigh more?]]

It's not just the number of molecules per unit area, it's their kinetic energy.

[[Cool temperatures cause air pressure to drop. When gas molecules cool, they move more slowly. Decreased velocity results in fewer collisions between molecules and air pressure decreases. Air density plays a role in the correlation between temperature and pressure because warmer air is less dense than cool air, allowing molecules to have more space to collide with greater force. In cooler air, the molecules are closer together. The proximity results in collisions with less force and lower air pressure.]] - https://sciencing.com/temperature-affect-barometric-pressure-5013070.html

[[The assertion that because the O2 and N2 in the atmosphere do not absorb visible or infrared radiation they are not absorbing radiated energy from the sun violates the law of thermodynamics which says that all objects absorb radiated energy.]]

Jeesh! Only Planck black bodies absorb all radiated energy, and gases aren't included, only solid or liquid objects with surfaces that can emit so many watts per square meter like Planck's Black Body Law says. Most gases at atmospheric temperatures don't absorb any radiated energy, only polar gases and only at specific wavelengths.

"To a first approximation gases do not emit black body radiation. You only see radiation from rotational, vibrational and electronic transitions, and these produce discrete lines. Gas molecules do interact when they collide, so if you increase the number of collisions by making the gas denser and hotter it will start to produce more black body radiation and eventually transition to radiation dominated by the black body spectrum." - https://physics.stackexchange.com/questions/222092/blackbody-or-characteristic-emission-of-radiation

As to UV light, yes, CO2 can absorb it at certain wavelengths, and does, in the stratosphere, providing a shield for solar flares. The stratosphere is above the bottom layer of the atmosphere, the troposphere, 6 mi. high. The rest of the UV light makes it to the ground after passing through all that atmosphere, although dust and smoke can block it. - https://earthobservatory.nasa.gov/features/UVB/uvb_radiation3.php

"How much UV light reaches the earth's surface?
Most of the natural UV light people encounter comes from the sun. However, only about 10 percent of sunlight is UV, and only about one-third of this penetrates the atmosphere to reach the ground, according to the National Toxicology Program (NTP)." - https://www.livescience.com/50326-what-is-ultraviolet-light.html

These are well-known facts, easy to Google. So, Rose is not as smart as a 5th grader?

No need for Rose to Google. He already knew it all by the 4th grade. I'm just as sure he'll never study or master real atmospheric physics, while I'm gaining more students every day for my cool free Climate Science 101 course, which straightens out the mess of IPCC lies and gives a crystal clear understanding of pure sweet thermal physics. Start studying now and join my new generation that will eat the world: To test how right I am, trying messaging your favorite IPCC climate science with my criticism of their lies and watch them block you because you're threatening their income.
