Fresh water is also heavier than salt, (or is it lighter?)and when it sinks (or rises?), it can alter abyssal circulation patterns. The more I look into it, the more complicated it gets.

But as one guy pointed out in one of the sites I review, (I paraphrase, from memory) "You can't continually add heat to a complex non-linear system without eventually generating a bad outcome."

My own intuition tells me that eventually the global heat engine will undergo a phase change, and then quickly stabilize at a new level. But more and more I'm hearing from people who know a lot more about this than I do that sooner or later some inflection point will be crossed and a runaway excursion event will be initiated.

Fortunately, by then we'll have a dictator in the White House who will instantly grasp the situation and immediately apply the right corrective action.
