Falsification Of The Atmospheric CO2 Greenhouse Effects Within The Frame Of PhysicsGlobal climatologists claim that the Earth's natural greenhouse effect keeps it 33°C warmer than it would be without trace gases in the atmosphere. 80 percent of this warming is attributed to water vapor and 20 percent to the 0.0385 volume percent of CO2. If CO2 exhibited such an extreme effect, however, this would show up as a thermal conductivity anomaly even in an elementary laboratory experiment. Carbon dioxide would manifest itself as a new kind of 'super-insulation,' wildly violating the conventional heat-conductivity equation.
Such anomalous heat transport properties never have been observed in CO2, of course.
Anyone can look at the data and understand that the earth does not emit radiation from the surface to space at more than a few discrete frequencies. If this were not so, then the surface temperature of the Earth would be identical to the surface temperature of the Moon. Heat radiating from the surface is captured by the atmosphere and that heat then drives convection which is the primary heat transport mechanism in the lower atmosphere.

The atmosphere does not eliminate radiation to space, it simply causes the majority of the radiation from Earth to space to take place at a higher altitude, where colder temperatures means a reduction in the amount of radiative heat emitted. Surfaces emit heat in a smooth curve across all frequencies. Atmospheres can only emit radiation in the discrete wavelengths of emission from each constituent molecule.
In the lower atmosphere, each gas constituent absorbs all radiation in its discrete wavelengths before it can escape to space, until at higher altitudes eventually there is not sufficient concentration of that type of molecule to absorb it, which results in that heat being lost to space. So the only effect of increasing CO2 concentration is raising the altitude where emission from the CO2 occurs.
If the relationship between temperature and radiation was linear, then there would be a slight increase in radiation with altitude, because there is more surface area the higher you go. However, radiation is related to the 4th power of temperature, which drives the relationship the opposite direction.
Interestingly, temperatures start to increase again at altitudes above 20,000 meters, so when CO2 doubles one or two more times it will start to cause increased heat loss to space. https://scied.ucar.edu/webweather/weather-ingredients/change-atmosphere-altitude
