10 degrees celsius is not energetic enough to radiate in the radio band, much less the IR.

The earth gives off heat, not IR.

I stopped reading there (sorry, I know you spent a lot of time on the rest).

You really need to read up on thermal radiation. From the Wikipedia page (emphasis mine):

Thermal radiation is electromagnetic radiation generated by the thermal motion of charged particles in matter. All matter with a temperature greater than absolute zero emits thermal radiation. When the temperature of the body is greater than absolute zero, interatomic collisions cause the kinetic energy of the atoms or molecules to change. This results in charge-acceleration and/or dipole oscillation which produces electromagnetic radiation, and the wide spectrum of radiation reflects the wide spectrum of energies and accelerations that occur even at a single temperature.

The "heat" we are talking about here is IR (Infrared Radiation); we don't actually see it, so it's not visible light. Why do you think they use infrared cameras as thermometers?

The ground does emit IR photons, and that process is different from conduction and convection. It is that infrared radiation, those infrared photons, that are captured by greenhouse gas molecules. The higher the concentration of greenhouse molecules in the atmosphere, the longer the IR photons stay in the atmosphere (and possibly hit the ground again). This means more lasting heat after the sun has gone down, which registers are a more pronounced warming at night than you'd expect if it was simply the sun being slightly hotter.

I'm sure the rest of your posts were the usual mix of erroneous claims, insults and vague threats of reporting me for things that aren't against the rules of reddit or of this subreddit. I told you I wasn't going to respond to these further in this thread, and I intend to do just that.
