To demonstrate what I am staying here and finding mutual ground. CO2 infrared emission can warm the cold ground slightly during the night. Energy flowing from excited state to less excitated state. It however cannot increase the temperature of the ground during the day when the sun is warming the ground. Because energy cannot flow from less excitated to more excitated.
That is true. The emission and absorption spectra apply to particular temperatures. If the food is warmed from 300 to 301 the spectrum will be a little higher and stretched. As you say, some of the heat will be absorbed by chemical changes or state changes in the food.
You cannot make something being warmed by absorbing visibile light,
Things warm in sunlight, both from the infrared and the visible. Plants and material inside a greenhouse warm from sunlight, and that is partly from the visible light and partly from the glass which absorbs the solar infrared.
You cannot make your sunburn worse with red light.
Sunburn is caused by radiation forming a new bond within a molecule. It is a molecule changing to a different kind of molecule, not a quantized energy change. The more obvious answer is that you cannot reverse sunburn by giving off UV.
You take two other metal rods warmed to 50 C and connect them to the 80 C metal rod. That will not increase the temperature of the 80 C metal rod. It will decrease the temperature of the 80 C rod and increase the Temperature of the 50 C rods
That is conduction, not radiation.
The temperature of the atmosphere and temperature of the ground are important determining factors and the sun-warmed ground will certainly provide more energy than the sky will to the ground. But there is no quantum effect that says: "hey there's an incoming photon that is less excited / lower energy level than my current state, so I will refuse to absorb it". Quantum mechanics is tricky though, and it can't be ruled out. But the answer does not lie in appeals to thermodynamics since it is not a closed system.
Nor is conduction a big factor in atmosphere to ground heat transfer. If it were, then your two metal rods touching would be a good analogy. While conduction is a factor, it is not a big factor.
Conduction is a primary factor in warming the atmosphere, which is what we are talking about. One of the main excess warming factors of CO2 is claimed to be from conduction. They are both processes of energy transfer.
So basically if these thermodynamics guys are correct, greater densities of CO2 and water vapor can only cause higher energy states at night. They cause lower energy states during the day. And that is precisely what we see. Coincidence or bad science ? We do know the fancy computer models have been horrible at fixture predictions lol.
Clarification - The energy states in the paragraph above refer to the grounds energy state. IE - The flames in the flame and ice cube comparison.
