re: I can agree with everything except
The concept that you are implying with this statement:
CO2 is a greenhouse gas, it does trap more heat in the earth's atmosphere- the physics of this is well understood and this is not an issue of any serious debate- it is simply a fact.
I do agree that CO2 is a greenhouse gas, it is used in greenhouses to improve the growth of plants, but it is not the gas that traps the heat, it is the glass or plastic windows that do the trick, they allow radiation to go through but prevent the raising air from “escaping to the space†above the building.
I can not understand how a freely expanding gas can do the same trick.
