🚨 Methane (CH₄; potent greenhouse gas) reached another preliminary record high value in December 2022 (1924.99 ppb).

Again, look in the upper-right corner...

December 2021's global methane abundance was 1908.84 ppb. Data available from https://gml.noaa.gov/ccgg/trends_ch4/.

@ZLabe That upcurve in the last half looks scary. Accelerating. :-( Not good.
@AnotherWealth @ZLabe What caused the flattening arount y2k?
Methane in the atmosphere is surging, and that's got scientists worried

Scientists love a good mystery. But it's more fun when the future of humanity isn't at stake.
