Is this just a guess? It seems to me entirely possible we may be a runaway mode right now. Measurements of the tundra surface show methane release is increasing and the area of thawing regions are increasing. The arctic is warming and the warming produces a strong postitive feedback effect. The environment has a capacity to convert CO2 to oxygen that is inversely related to temperature. It could take a long time to cook us all, but that doesn't change the fact that a feedback driven runaway is unstoppable except possibly by unprecedented world scale efforts, or a dramatic shift in ocean currents.
