Methane gas has devastating effects on the climate system and its extraction and combustion generate numerous harms to human health. Compared to carbon dioxide (CO2), methane doesn’t linger for long in the atmosphere after being emitted. But during the decade it does linger, its heat-trapping potential is 80x stronger than CO2.
