Suppose that a CO2 molecule in the atmosphere absorbs a photon of electromagnetic radiation. Because the photon carried energy and energy cannot be created or destroyed, the energy that the photon carried must now be present in some form in the CO2 molecule. In fact, at the moment the photon was absorbed, the CO2 molecule began to Based on this, we can conclude that the photon absorbed was a photon of radiation.
