The runaway effects are exactly the concern. Check out research on methane clathrates in the Mesozoic. Methane is 24x as potent a GHG than CO2.
When you see the gas flares in hydrocarbon production fields it may look like a waste (it is), but it has to be done because the alternative of releasing methane into the atmosphere is worse.
