Greenhouse Gases

Greenhouse gases are gases in the atmosphere that absorb and emit radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. Common greenhouse gases in the Earth’s atmosphere include water vapour, carbon dioxide, methane, nitrous oxide, ozone, and chlorofluorocarbons.
