re: #85 LudwigVanQuixote

The earth is warmed by the sun. The energy in the light of the sun is of greater energy, intensity along with frequency. That light can either be absorbed or reflected by an object. If absorbed and warmed the body will radiate IR to help in cooling. The IR is of less enegy, intensity and frequency. Having less energy,intensity and frequency when the IR is absorbed and re-radiated by a molecule it cannot warm the earth to any degree above what the light of the sun did.
