Proof About Carbon Dioxide

by Richard
(United States)

I note that you make the following statement as a statement of fact. Where is your proof for this statement. "For every extra molecule of CO2 in the atmosphere, additional heat is reflected down back towards the Earth. This means that some heat that would otherwise have been lost from the atmosphere is trapped. Given large enough quantities of CO2 in the atmosphere the amount of trapped heat will cause a rise in the temperature of some parts of the atmosphere."

In regard to the previous comments...

I have no proof myself that increased CO2 levels result in increased atmospheric heat trapping aside from referring again to the chemical properties of the molecule.

I suspect that climate modelers use this property of CO2 to absorb and release heat in their modeling, but I am not certain. It does make sense though that if one molecule has this effect, lots of molecules will have the same effect only larger.

Regarding geothermal energy, I believe it is a valid renewable energy although it does run the same risk as fossil fuels, being a net increase in the amount of energy in the atmosphere. The advantage of solar and wind over geothermal is that they harness energy that is already in the atmosphere, rather than adding energy or extra gases to that atmosphere.

Why not harness the extra heat by employing the use of thermoelectric generators and creating an awesome source of electricity?

My question remains. Let me state it in a different way. What proof can you offer that a concentration of 500 PPM of CO2 in the atmosphere would cause global temperatures to rise when compared to a concentration of 250 PPM of CO2 in the atmosphere.

I base this on the chemical properties of CO2 one of which is to absorb and radiate infra red energy. This energy comes from the surface and prior to absorption is heading out into space. The CO2 molecule emits this energy in all directions, with the overall result being that some of the energy that would otherwise have gone into space gets re-emitted back to the ground.
