“There are enough CO2 molecules in 0.04% to absorb every infrared photon emitted from the earth’s surface in the first 10 meters of atmosphere.”
Which is why we have thermal imaging satellites picking up IR from the Earth’s surface in space, because CO2 absorbs all IR photons “in the first 10 meters of the Earth’s Surface”?
Where did you read this line of BS?
Because the same CO2 molecules also emit the same wavelength photons that they absorb. The important point is that the transfer of energy from CO2 molecules to N2 and O2 molecules is a much faster process than the emission. So the atmosphere warms. But the same CO2 molecules act to cool the atmosphere. They do that by emiting about 1/2 the molecules out to space, and 1/2 back to earth. The best way to think about it is layers of atmosphere. Each layer absorbs photons (over certain wavelengths), warms, emits photons and cools. It is the emitting that keeps the layer below a little warmer than it would be otherwise.
