Main greenhouse gases
Philippe Rekacewicz, UNEP/GRID-Arendal
The table lists some of the main greenhouse gases (such as carbon dioxide, methane, and freons) and their concentrations in pre-industrial times and in 1994; atmospheric lifetimes; anthropogenic sources; and Global Warming Potential. Greenhouse gases are a key factor in global warming, as they trap the radiating heat in the atmosphere, reflecting it back to the atmosphere.
