Methane - Climate Change: Vital Signs of the Planet
Methane (CH 4) is a powerful greenhouse gas, and is the second-largest contributor to climate warming after carbon dioxide (CO 2). A molecule of methane traps more heat than a molecule of CO 2, but methane has a relatively short lifespan of 7 to 12 years in the atmosphere, while CO 2 can persist for hundreds of years or more.
