Methane (CH 4) in the Earth's atmosphere is a powerful greenhouse gas with a global warming potential (GWP) 84 times greater than CO 2 over a 20-year time frame. [22][23] Methane is not as persistent as CO 2, and tails off to about 28 times greater than CO 2 over a 100-year time frame. [10]
The global warming potential (GWP) is defined as an "index measuring the radiative forcing following an emission of a unit mass of a given substance, accumulated over a chosen time horizon, relative to that of the reference substance, carbon dioxide (CO 2). The GWP thus represents the combined effect of the differing times these substances ...
For example, plants that produce methane can emit as much as two to four times more methane during the day than during the night. [45] This is directly related to the fact that plants tend to rely on solar energy to enact chemical processes. Additionally, methane emissions are affected by the level of water sources.
Methane, the main component of natural gas and a byproduct of fossil fuel drilling, is a powerful source of climate pollution with more than 80 times the warming power of carbon dioxide during its ...
The industry currently accounts for only 1% of global investment in clean energy, and continues to pump out disastrous quantities of planet-heating gases, including methane, which is roughly 80 ...

Methane (CH 4) is one of the more potent greenhouse gases and is mainly produced by the digestion or decay of biological organisms. It is considered the second most important greenhouse gas, [10] yet the methane cycle in the atmosphere is currently only poorly understood. [11] The amount of methane produced and absorbed yearly varies widely. [10]
