This is the problem right here. This is a matter of uncertainty, risk and chaotic systems. There is no definitive answer to this question, but because of the chaos of the system there is a risk it could be soon. For fun, go and read up on the likely failure mechanism of the Greenland ice-sheet. There's a decent chance that it won't release water slowly, but thaw from the middle out, dammed in by the frozen edges. This is already happening. Then a seismic event or a few really hot days could cause the dam to break. Then the action of the flowing water increases the ice sheets ability to transfer heat and the thing might fall to bits in a matter of months.

But that's the thing, we don't know when that might happen, any more than we know when and where the next earthquake will be.
