Although methane doesn’t linger very long in the atmosphere, increasing methane levels are particularly bad news because it packs a big punch. But its short lifetime in the atmosphere is also a reason for hope. It is 80 times stronger than carbon dioxide (CO2) at trapping heat on short timescales. The planet has already warmed 1.1

In the long run, warming will be determined by how much carbon we pump into the atmosphere before we stop. If we can shave down the curve even a little, we reduce the ultimate tonnage of carbon lingering in the atmosphere. The answer is unequivocally “yes.”. In terms of emissions cuts, the basic rule is simple: Every ton counts.
