when plants die and rot, nitrous oxide is produced.
A mixture of methane (CH4) and carbon dioxide (CO2) produced by anaerobic digestion, with small amounts of other gases.
Sudden release of methane from its ice complex, clathrate, has been hypothesized as a cause of past global warming. Two events possibly linked in this way are the Permian-Triassic extinction event and the Paleocene-Eocene Thermal Maximum.

Greenhouse gases include carbon dioxide, methane, nitrous oxide, chlorofluorocarbons (CFC's) and water vapour. Carbon dioxide, methane and nitrous oxide have significant natural and human sources while only industries produce CFC's.
water vapour, carbon dioxide, methane). These gases absorb radiation emitted by the Earth, thereby retarding the loss of energy from the system to space.
(Here's why.) And composting your waste food means it doesn't have to be trucked away to a landfill waste dump where it will cause more pollution including methane, a powerful greenhouse gas. [why doesn't composting make methane?
