When I talk about the MOC system, I do it to say the good news is that Younger Dryas type event is looking a lot less likely this century then scientists thought a decade ago. I do that to short circuit it coming up in questions. Nevertheless, from WGII Summary for Policy Makers, significant slowing is still in there as we push out over 2 degrees C. So I am on the fence whether, as a lay policy person, I should keep it in the mix of what I talk about as non-linear abrupt climate change scenarios. "Gulf stream shut down" is sort of the short hand for all this--- can you suggest alternate easy language? As to ocean acidification, understood that it is a continuous problem-- but is it not fair to say that it will get worse as we emit more? And that catastrophic ecosystem threshholds are are more likely to be crossed as we emit more? Thanks for any guidance you can provide here. Eban Eric, thanks for the comment.

Perhaps because many of us in the scientific community keep confusing people on this issue. Strictly speaking, "shut down of the Gulf Stream" is pretty much impossible, since it driven by the winds, which are driven by the Earth's rotation. Changes in ocean's poleward heat flux are possible, but unlikely to be significant. Most of this stuff is way way overblown in the literature, in spite of the fact that the originator of this idea (Wally Broacker) no longer believes it himself. We've addressed this more than once at RealClimate.org. (http://www.realclimate.org/index.php/archives/2006/10/carl-wunsch-the-economist-and-the-gulf-stream/). The facts are scary enough without this silly "Day After Tomorrow" scenario opening us all up to criticism from the denialists. It would be more honest, and more effective, to stop talking about it in the same breath as sea level rise or ocean acidification, both of which are certain, not speculative. (By the way, ocean acidifcation should not be listed under your category of "if the warming is at the higher end of the range, consequences will be catastrophic." Ocean acificiation is a major problem even at the low end of the range.)
