Earlier quoted context omitted.
This is what my quick google turned up [1]. > A molecule of methane traps more heat than a molecule of CO2, but methane has a relatively short lifespan of 7 to 12 years in the atmosphere, while CO2 can persist for hundreds of years or more. Doesn't mean it's correct though so I'd be happy to see different thinking on this. That being said, IIRC, isn't one of the models for the increasing methane the melting permafros…
https://climate.mit.edu/ask-mit/why-do-we-compare-methane-ca... "Over 20 years, the methane would trap about 80 times as much heat as the CO2. Over 100 years, that original ton of methane would trap about 28 times as much heat as the ton of CO2." So converting a bunch of atmospheric CO2 to methane evey year is not good.
