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.

- Methane facts and information - National GeographicMethane is a simple gas, a single carbon atom with four arms of hydrogen atoms. Its time in the atmosphere is relatively fleeting compared to other greenhouse gases like CO 2 —any given methane ...
- Importance of Methane | US EPAMethane (CH 4) is a hydrocarbon that is a primary component of natural gas. Methane is also a greenhouse gas (GHG), so its presence in the atmosphere affects the earth’s temperature and climate system. Methane is emitted from a variety of anthropogenic (human-influenced) and natural sources.
- Facts about Methane | UNEP - UN Environment ProgrammeMethane is increasingly a global climate priority, with ambition for addressing emissions building among both governments and companies.
