Even though it only makes up 0.00017% (1.7 parts per million by volume) of the the atmosphere, methane traps a significant amount of heat, helping the planet remain warm and habitable.ASA Earth Observatory. download large image (4 MB, PDF).

Methane (CH4) is a greenhouse gas. It affects the radiation budget of Earth directly (by intercepting heat radiation) but also indirectly, by reacting with other trace gases in the atmosphere, and by delivering water molecules upon oxidation in the stratosphere.ethane is relatively short-lived in the atmosphere; a molecule of methane is oxidized to water and carbon dioxide within a decade or so, mainly by reaction with another trace gas, the hydroxyl radical OH-.
