atmospheric methane:20
methane in the earth's atmosphere is a strong greenhouse gas with a global warming potential (gwp) 104 times greater than co2 in a 20-year time frame; methane is not as persistent a gas as co2 (assuming no change in carbon sequestration rates) and tails off to about gwp of 28 for a 100-year time frame.
