Nobody checked the carbon-13 ratios!Wouldn't you know it — 150 nations signed the Global Methane Pledge without even bothering to check if the methane was man-made.Methane — the second most hated Greenhouse gas —
spiked to record historic levels in the last few years, over
1,900 parts per billion. In 2019, even the WEF scientists admitted
they couldn't explain the baffling rise, and then in 2020, the world of methane went into the twilight zone. We shut down the modern world due to the pandemic, and methane levels rose even faster.
It seems many have been blaming fossil fuels for the global surge in emissions, but forgot to check the C13 isotopes. Somehow we spend millions on
breathalysing cows, measuring their burps, and feeding them seaweed, but didn't think to do the basic chemistry. How could that be, you might wonder... 158 nations agreed to cut methane emissions by 30% by 2030, but none of them audited the science even though very strange things were happening. (The point was obviously the "pledge", the junkets, the captive industries and subsidies,
anything but the science).
Methane from fossil fuels has a higher carbon-13 ratio, but even though fossil fuel use was rising, the carbon-13 levels of atmospheric methane was rolling down a hill. Indeed this new study shows
it's been falling for 17 years.It's not like this snuck up on us.... any inquiring mind should have seen this coming a decade ago. The lab has been recording C13 in methane since 1998 and gets air samples from 22 sites around the world every week or two.

Mean growth rates of CH4 mole fraction and δ13CCH4 are shown for the following time periods: 1983–1998, 1999–2006, 2008–2014, 2014–2020, and 2020–2022.
