1. Methane

   Methane (US: MEH-thayn, UK: MEE-thayn) is a chemical compound with the chemical formula CH4 (one carbon atom bonded to four hydrogen atoms). It is a group-14 hydride, the simplest alkane, and the main constituent of natural gas. The relative abundance of methane on Earth makes it an economically attractive fuel, although capturing and storing it poses technical challenges due to its gaseous state under normal conditions for temperature and pressure. Naturally occurring methane is found both below ground and under the seafloor and is formed by both geological and biological processes. The largest reservoir of methane is under the seafloor in the form of methane clathrates. When methane reaches the surface and the atmosphere, it is known as atmospheric methane. The Earth's atmospheric methane concentration has increased by about 150% since 1750, and it accounts for 20% of the total radiative forcing from all of the long-lived and globally mixed greenhouse gases. It has also been detected on other planets, including Mars, which has implications for astrobiology research.

1. methane

   Methane is a colorless, odorless, flammable hydrocarbon gas that is the simplest organic compound, consisting of one carbon atom and four hydrogen atoms. It is the main constituent of natural gas and is also released by the decay of plant or animal matter. It is considered a greenhouse gas as it can trap heat in the atmosphere, contributing to global warming. Its chemical formula is CH4.

1. Methane

   Methane is a chemical compound with the chemical formula CH 4. It is the simplest alkane and the main component of natural gas. The relative abundance of methane makes it an attractive fuel. However, because it is a gas at normal conditions, methane is difficult to transport from its source. Methane is a potent greenhouse gas, more potent than carbon dioxide unit per unit. The concentration of methane in the Earth's atmosphere in 1998, expressed as a mole fraction, was 1745 nmol/mol, up from 700 nmol/mol in 1750. By 2008, however, global methane levels, which had stayed mostly flat since 1998, had risen to 1800 nmol/mol.

1. Methane

   meth′ān, n. marsh-gas, the simplest hydrocarbon, found wherever the decomposition of vegetable matter is taking place under water, also in coal-mines, forming when mixed with air the deadly fire-damp.—n. Methanom′eter.

1. Methane

   The simplest saturated hydrocarbon. It is a colorless, flammable gas, slightly soluble in water. It is one of the chief constituents of natural gas and is formed in the decomposition of organic matter. (Grant & Hackh's Chemical Dictionary, 5th ed)

Examples of Methane in a Sentence

1. The USGS:

   When hot lava buries plants and shrubs, methane gas is produced as a byproduct of burning vegetation, methane gas can seep into subsurface voids and explode when heated, or as shown in this video, emerge from cracks in the ground several feet away from the lava. When ignited, the methane produces a blue flame.

2. Riley Duren:

   There really have been transformational advances in remote sensing technology for methane over the last decade and the last three to four years, that reporting program doesn’t require operators to go out and fly airplanes. It’s largely based on models and standard emissions factors.

3. Robert Jackson:

   For carbon dioxide, we've always known about power plants and smokestacks and things like that ; but with methane, until recent years, we didn't understand how much an influence a small number of large sources have really had, we didn't understand how long the tail was and how important the super-emitters were for reducing emissions.

4. Rosaly Lopes:

   Titan has an active methane-based hydrologic cycle that has shaped a complex geologic landscape, making its surface one of most geologically diverse in the solar system.

5. Lujan Grisham:

   The data we are looking at today strongly suggests we can clean up 80% of the methane problem.
