Methane (US: / ˈ m ɛ θ eɪ n / METH-ayn, UK: / ˈ m iː θ eɪ n / MEE-thayn) is a chemical compound with the chemical formula CH 4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas.

Nov 12, 2024 · Methane, colorless, odorless gas that occurs abundantly in nature and as a product of certain human activities. Methane is the simplest member of the paraffin series of hydrocarbons and is among the most potent of the greenhouse gases.

Methane Basics. 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 is the major component of natural gas, which is found in geological deposits known as natural gas fields and used as vehicle fuel in its compressed form. Methane may be burned to produce electricity and is often piped into homes for domestic heating and cooking purposes.

Jan 23, 2019 · Methane's impact on climate, past and future. Methane may also have been the cause of rapid warming events deep in Earth’s history, millions of years ago.

5 days ago · Greenhouse gas - Methane, Climate Change, Emissions: Methane (CH4) is the second most important greenhouse gas. CH4 is more potent than CO2 because the radiative forcing produced per molecule is greater.

Mar 3, 2025 · Methane (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.

Jan 28, 2025 · Methane(CH₄) is a colorless, odorless gas that plays a crucial role in both the environment and the energy sector. It is the simplest form of a hydrocarbon, consisting of one carbon atom bonded to four hydrogen atoms ( CH₄ ).

Jul 19, 2024 · Methane (CH4), the primary component of natural gas, is responsible for approximately a third of the warming we are experiencing today.

Methane is an organic compound with the chemical formula C H 4. It is an alkane with one carbon atom. It is often found as the main part of natural gas. Methane is a greenhouse gas [4] [5] 23 times more effective than carbon dioxide. It is also less stable and slowly oxidates by oxygen to carbon dioxide and water.
