See what's wrong with that argument?

What's wrong is that the rate of biogenic (from cows, termites, wetlands &c) methane generation is not more than would naturally happen, just as CO2 emission from animal metabolism is not more than natural. It's the non-natural things, like natural gas leaking from oil wells, that's causing the increase.
