Naturally occurring greenhouse gases include water vapor‚ carbon dioxide‚ methane‚ nitrous oxide‚ and ozone. Certain human activities‚ however‚ add to the levels of most of these naturally occurring gases: Carbon dioxide (CO2): released into the atmosphere when solid waste‚ fossil fuels (oil‚ natural gas‚ and coal)‚ and wood or wood products are burned. Methane (CH4): emitted during production and transport of fossil fuels (coal‚ natural gas‚ and oil‚) from the decomposition of organic wastes
