(I'm not saying you are wrong just find it curious.) of course there's still methane in atmosphere, about 0.00016 if I remember correctly. As 0.00016*23 would be 0.00368. That means the effect of methane on the global warming is about 10 smaller as CO2. But that would also mean that the only a small increase of C2H6 would mean a much bigger effect than CO2 would. SO why are all those scientist worrying about CO2? (ofcourse you also have NOx and H2O)

Methane is, kg for kg, 23 times more powerful as a greenhouse gas than carbon dioxide, so if you were to release equal amounts of methane and carbon dioxide into the atmosphere, the methane would do much more damage. The total effect of all the methane is the atmosphere is most likely less than the total effect of all the carbon dioxide in the atmosphere, however.
