The majority of them are not, though there are some. A greenhouse gas is simply any chemical compound that traps solar energy in the atmosphere as heat. The biggest greenhouse gases include water vapor, carbon dioxide, methane, nitrous oxide, and ozone, plus a variety of synthetic compounds (hydroflourocarbons and chloroflourocarbons, for example). Many of these gases exist at low concentrations in nature anyway. Water vapor and carbon dioxide are clearly nontoxic, as are methane, nitrous oxide, and ozone. Methane is the gas released in farts (smelly but not toxic) while nitrous oxide is used as laughing gas. Some, such as CO2 or methane, have the ability to displace oxygen in enclosed places and cause asphyxia, but aren’t toxic on their own. One example of a toxic greenhouse gas is a new chemical pesticide sulfuryl fluoride developed by Dow and applying for testing.
