I suppose that with complex systems, specially the ones with some fragility or in some sort of equilibrium that only can sustain push below some threshold, a big enough disturbance will put it off balance, and everything that emerges from that will probably end being negative. Think in someone balancing itself standing over a ball, and get hit by a strong wind, if the things he does are not very precise and in the right direction he will fall, but maybe not in the direction of the wind that pushed him. And we don't have something actively trying to rebalance the system, nor our current understanding will let us be precise at the time of messing with it somewhat to try to fix this. In any case, we are talking about hotter sea currents, and the ocean is absorbing a lot of the extra heat both by having more greenhouse gases, and positive feedback loops triggered by them like the melting of floating ice (so less albedo, and the ocean gets more heat from the sun).
