text: Methane in the Earth's atmosphere is a strong greenhouse gas with a global warming potential (GWP) 84 times greater than CO 2 in a 20-year time frame; methane is not as persistent a gas as CO 2 (assuming no change in carbon sequestration rates) and tails off to about GWP of 28 for a 100-year time frame.[page needed]
