All organic material creates methane as it dies and rots. Also methane gas a relatively short half life of under ten years. Agriculture only accounts for about 5% of methane release, and the includes other inputs, such as fertilizers, transport, etc...
I'm not disputing that beef has some effect, but just think previous calculations I'd seen seemed way to simplistic. If the option is eating free range beef raised locally or imported soy products grown on factory farms, the choice isn't as simple as beef is always worse because cows fart a lot.
