In the long term, the earth must shed energy into space at the same rate at which it absorbs energy from the sun. Solar energy arrives in the form of shortwavelength radiation. Some of this radiation is reflected away by the earth's surface and atmosphere. Most of it, however, passes straight through the atmosphere to warm the earth's surface. The earth gets rid of this energy (sends it back out into space) in the form of long wavelength, infra-red radiation.

Over the last few years, thanks to international scientific evidence, there has been increasing recognition of the threat of climate change caused by a dramatic increase in anthropogenic greenhouse gas (GHG) concentrations.
