When methane's "residency time in the atmosphere" is over, doesn't that mean it's just converted to CO2? So wouldn't that mean its time is effectively 1.25x CO2

When methane's "residency time in the atmosphere" is over, doesn't that mean it's just converted to CO2? So wouldn't that mean its time is effectively 1.25x CO2's?
I'm actually asking, I have a lot of gaps in my knowledge on this.
- mercutio2 8y agoBecause each molecule is more potent before breaking down than a long-resident CO2 molecule, you’re talking about a much smaller mass of CH4 per unit of forcing. Of course our knowledge of all the current and emergent syncs and sources for all GHG emissions is an evolving science, so we can’t speak with precision about all this.
