Globally, atmospheric methane levels have been on the rise over recent years. And though the rate of rise is not as dramatic as seen during the late 1980s (yet), the relative rise of atmospheric methane has caused concern among scientists.
Methane is a major heat trapping gas. And it is the #2 driver of human-forced global warming behind fossil fuel burning based CO2 according to NOAA’s Earth Systems Research Lab. It also has an out-sized potential to swing global heat trapping values higher due to the fact that a single molecule of methane can trap around 86 times more heat than a single molecule of CO2 over the same period of time.
(Global trends in methane show a concerning jump in atmospheric values since leveling off in the mid-2000s. A combination of earth environment feedbacks to warming and fossil fuel related extraction, burning and transport activity are primary suspects…
