RRecent studies are showing that "Methane concentrations in the atmosphere have risen at a “dangerously fast” rate and now exceed 1,900 parts per billion, prompting some researchers to warn that climate change itself may be driving the increase." https://www.theenergymix.com/2022/02/14/dangerously-fast-methane-increase-suggests-feedback-mechanism-may-have-begun/?fbclid=IwAR11llxcskYZcmMXVR1b4BebCQpNArHAQEI3uHfHoQjV138bWNylKsPq-cI
Atmospheric methane levels are now nearly triple pre-industrial levels, a news article in the journal Nature states, citing data released last month by the U.S. National Oceanic and Atmospheric Administration (NOAA). “Scientists says the grim milestone underscores the importance of a pledge made at last year’s COP 26 climate summit to curb emissions of methane,” a climate pollutant that Nature cites as at least 28 times more potent than CO2, but is actually 80 to 85 times more damaging over the 20-year span when humanity will be scrambling to get the climate emergency under control.
