the natural greenhouse effect the natural greenhouse effect is a phenomenon caused by gases naturally present in the atmosphere that affect the behaviour of the heat energy radiated by the sun in simple terms sunlight shortwave radiation passes through the atmosphere and is absorbed by earth s surfacehis warms earth s surface and then earth radiates some of this energy as infrared or longwave radiation back towards space as it passes through the atmosphere gases such as water vapour carbon dioxide methane and nitrous oxide absorb most of the energy
