>Within a generous range, this system is very stable and adaptive. There have been some very accessible pieces published in Scientific American over the years that describe the current models and go on to explain the various sources and sinks in the global CO2 cycle.>

Ultimately, in complicated systems, the qualitative model is not sufficient, but useful as a reality check. The quantitative models can be reasonably accurate within the limits of the set of assumptions used to develop the models.

As you say, within a generous range, this system is very stable and adaptive. However, the important question is: how badly could the slightly larger perturbations affect life in "internet time", and not whether the system will stabilize in geological time? After all, 3000 people dying in a twin tower implosion is a minuscule percentage in the scale of humankind mortality rate, but has large implications on the political life of the world, which can multiply this affect thousand times, for example if nuclear weapons get used.
