Is atmospheric heat, thermal radiation from the air or from the earth? Author; Rogelio Pérez C Summary; The greenhouse effect is defined as the natural phenomenon that certain gases present in the atmosphere (CO2) retain part of the thermal radiation emitted by the earth's surface after being heated by the sun, So this work shows that the greenhouse effect has nothing to do with infrared radiation from other systems, trapped in the atmospheric system by certain gases like CO2, but this infrared that we see in the air, it is originated by the gas molecules that make up the atmospheric system that we call air, due to their own kinetic movements, but because the air is invisible we can only see infrared radiation, and we believe that this infrared radiation is the one that is transferring heat to us, when the truth is that the heat transfer is due to the invisible mass of the air, when we come into contact with it. Introduction; The problem of climate change is mainly due...
