That's true, and I hadn't considered that angle too much. However, methane's greenhouse effect is 25 times more potent[1] than the one of CO2, so converting carbon to methane is worse than just burning it. And lastly, farming meat is not neutral either: at the very least, that's land you're not going to use as forest (carbon sink). And then there's the other net emissions. I think the IPCC is doing a very thorough job at getting accurate estimations. They have many lobbies to go against, which will carefully examine discrepancies on their reports. Like wikipedia, having persons of different opinions and interest cooperate on a report, the report comes out as generally more objective and accurate, as that's the only compromise acceptable by both parties.
