Greenhouse+Effect

The ** greenhouse effect ** is a process by which thermal radiation from a planetary surface is absorbed by atmospheric [|greenhouse gases], and is re-radiated in all directions. Since part of this re-radiation is back towards the surface, energy is transferred to the surface and the lower atmosphere. As a result, the average surface temperature is higher than it would be if direct heating by solar radiation were the only warming mechanism. [|[1]][|[2]]
