Methane Facts:
Methane is a powerful greenhouse gas that traps heat 28 times more effectively than carbon dioxide over a 100-year timescale.The effects aren’t just hypothetical: since the Industrial Revolution, methane concentrations in the atmosphere have more than doubled, and about 20 percent of the warming the planet has experienced can be attributed to the gas.
Methane Sources:
There are six major sources of atmospheric methane emissions from anaerobic decomposition: natural wetlands, paddy rice fields, emission from livestock production systems (including animal waste), biomass burning (including forest fires, charcoal combustion, and firewood burning), anaerobic decomposition of organic waste in landfills, and fossil methane emission during the exploration and transport of fossil fuels. In addition, National Geographic declares that human activity is driving up the levels of the destructive greenhouse gases.
