We know what methane does.
In cow farts it's melting the polar ice caps, right?
And we're not exactly sure when but some day...
Right, because your advanced degree in climate dynamics, with a minor in physics and meteorology tells you methane has no effect on our atmosphere's ability to retain heat.
Cows aren't the only cause, but they contribute. The same way drinking 4 cans of coke isn't making you fat by itself, but in conjunction with the box of twinkies, 3 chocolate bars, and 6 meals you eat a day it adds up, so you reduce your calories where you can.
It's not opinion. It's science. And it's not science theory, it's science fact.
