How Many Cowpower is That?

I didn't read the article since the link seems to be broken, but I assume you're right:

CH4 (methane) + 2 02 (oxygen) -> 2 H2O (water) + CO2

But, considering that the greenhouse effect of methane is much larger than that of CO2, this is not a problem.

On a related note, many gasses have an effect on the greenhouse phenomenon. CO2 is the most famous one because it's the one that varies the most, and the one that (according to most scientists) has an increasing concentration due to human activities.
