Enteric methane produced in 2008 was less than that produced in 2000 and virtually the same as in 1998.
Methane oxidises to CO2 in 8-12 years so we can all sleep soundly in our beds knowing that all the enteric methane produced today is only replacing the methane that was produced ten years ago. The atmospheric concentration of methane will not have altered at all.
So indisputably, no global warming from enteric methane!
Unfortunately there are still some plonkers out there who think enteric methane is a problem. One can only wonder with incredulity.
If all the fossil fuel emissions of CO2 were tracking as those from enteric methane are, there would be no global warming industry at all, because there would be no problem.
