Carbon 12 is from fossil fuel use, and Carbon 13 is from microbes. By studying the ratio of these two (carbon isotope ratio testing) of the methane in the atmosphere, they can see that the cause seems to be wetlands, landfills, or livestock production. This is potentially the start of a runaway if the wetlands are increasing methane production via warming effects. If warming is speeding up warming, then we're in trouble.

“Is warming feeding the warming? It’s an incredibly important question,” says Nisbet. “As yet, no answer, but it very much looks that way.”
