My reply:

[[the top layer of the atmosphere must emit 239.7 W/m2 of infrared radiation to space (same amount of solar radiation that enters the atmosphere: what goes in must go out).  The bottom layer of the atmosphere will emit an equal amount downward to the surface of the planet.  Hence, for thermal equilibrium, the surface of the planet must emit enough radiation to balance not only the amount it receives from the sun (239.7 W/m2), but also what it receives in the form of downward infrared radiation from the atmosphere 239.7 W/m2). Hence, its emission must match 239.7+239.7 = 479.4 W/m2.  Applying the Stefan-Boltzmann law: constant x T4= 479.4 W/m2.We thus calculate T = 303 K.”]]

Zonk!There is almost no downward IR from the atmosphere, as measured by the
Atmospheric Emitted Radiance Interferometer (https://www.ssec.wisc.edu/aeri/). It's in milliwatts per square meter not watts per square meter.That's because gases can't emit Planck radiation, or any radiation at all unless they're polar, and that kind of radiation is photon by photon not a power-wavelength curve with a S-B T^4 integral like solds and liquids emit.Any time you see a diagram of Earth's atmosphere showing big arrows coming out of thin air, skip the page.

Neither is there any radiation balance between the Earth and the Sun. How can there be when a good portion of solar radiation ends up being converted to kinetic energy then potential energy via convection? Plus, it's totally illegitimate to try to equate the Sun's energy that's mainly in the visual range of 0.4-0.8 microns (6971C-3349C) with the surface's energy that's in the range of 12.986 microns (-50C) to 8.967 microns (+50C). The Earth's atmosphere is a giant Carnot engine, which uses up solar energy to create winds and weather. Once used up, it's gone, converted to potential energy. Anybody pushing the fake physics CO2 warming hoax that mentions radiation balance should be cancelled quick. If they are talking about the dead lifeless atmosphereless Moon, they can use the S-B Law all they want since there's no convection to worry about.
