A tiny amount of something can never heat a large amount of something under any set of conditions. Nothing resembling it is found anywhere in science. This is why parts per million greenhouse gasses cannot heat the atmosphere. Heat doesn't do that without nuclear reactions.
The second law of thermodynamics says heat dissipates, all the time, everywhere, without exception. There cannot be a greenhouse effect in the atmosphere because of the second law of thermodynamics.
Heat cannot be trapped in the atmosphere. Large amounts of heat move into and out of the atmosphere constantly, as temperatures change 20 degrees or more between day and night.
Absorbed radiation is emitted in 83 femto seconds. All matter emits radiation constantly.
This miniscule nonresult must be divided by 2,500, because surrounding molecules dilute it that much. There are 2,500 air molecules surrounding each CO2 molecule when carbon dioxide is at 400 parts per million in the atmosphere. Therefore, to heat the air 1°C, each CO2 molecule would have to be 2,500°C—an impossibility.
If the heat isn't trapped, it can't spread to the other 2,500 molecules.
