A great many processes in nature reach a tipping point where they switch from gradual to rapid. A point could occur where all the ice suddenly slips into the seas in a matter of days or <<weeks. Must agree--there are many climate models but the climate certainly involves some nonlinear dynamics and a major component of non-linear dynamics is the theory of bifurcations, these being points in the slow evolution of a system at which qualitative changes or even sudden jumps of behavior can occur (tipping point). We can already see evidence that positive feedback loops are starting to engage. Some areas to worry about include Arctic summer sea-ice and the Atlantic thermohaline circulation as possibly being subject to bifurcations--among several others.
