Now, if you should never trust a number, why do I trust these? Problems with a number usually boil down to either “the number is incorrect” or “you misunderstand what the number means”. The most important number here (12 years) comes from the latest IPCC report, which is very carefully vetted, so I’m comfortable that it’s not flat out wrong. And as summarized in this post, I’ve put in enough work to be confident that I understand exactly what the IPCC report means by “perturbation methane lifetime”. As a bonus, I now have a mental model that I can use to evaluate numbers I encounter in the future.
