climate system
some trace gases in the atmosphere, such as water vapour and carbon dioxide, are the gases most important for the workings of the climate system, as they are greenhouse gases which allow visible light from the sun to penetrate to the surface, but block some of the infra-red radiation the earth's surface emits to balance the sun's radiation.
