Global methane emissions are major part of the global greenhouse gas emissions. Methane in the atmosphere has a 100-year global warming potential of 34. Atmospheric methane concentrations have reached almost two-and-a-half times pre-industrial levels or 3.2 billion tons. Though methane traps far more heat than the same mass of carbon dioxide, it remains in the atmosphere only about a decade, while carbon dioxide warms for a much longer time period. On a 20-year timescale, a mass of methane is about 85 times more powerful than carbon dioxide at warming the Earth, but on a 100-year timescale, it is only about 28-34 times more powerful, because the carbon dioxide continues to warm the earth after the methane is gone.
