In addition to carbon dioxide, the EPA said five other emissions are believed to cause warming when they concentrate in the atmosphere: methane, which is emitted by gassy cows as well as steam boilers; nitrous oxide, found in cooking sprays and used as anesthesia by dentists, better known as laughing gas; hydrofluorocarbons, which are used in refrigerators and aerosols; perfluorocarbons, a gas permeated by fire extinguishers, refrigerators and high end ski waxes; and sulfur hexafluoride, more commonly known for its use in circuit breakers, switchgear and other electrical equipment.

There were some stories a couple of months ago on it, when the public comment part came out.
