Failing Ocean Current Raises Fears of Mini Ice Age

Designadrug writes "This article from Newscientist paints a picture of a major climate control mechanism teetering on the brink: "The ocean current that gives western Europe its relatively balmy climate is stuttering, raising fears that it might fail entirely and plunge the continent into a mini ice age. The dramatic finding comes from a study of ocean circulation in the North Atlantic, which found a 30% reduction in the warm currents that carry water north from the Gulf Stream.""

So what happens to all that energy?

[ReformedExCon]

If the current is pulling all that energy from the warm waters up north and dissipating it in the process, what will happen to all the excess warmth if the current stops? Will it find another way to go? Maybe create a new current or even restart the same current again? That heat has to go somewhere, it is water after all.

i've seen that website before and i decided to run a few calculations on it. now while you might think that that is a miniscule mean temperature change in the atmosphere, when one multiplies that 0.001227436 C by the ~725(depends on exact density, doesn't vary much) joules needed to raise the temperature of mixed air by one degree centigrade and the 5.1*10^18 kilograms of air in the lower atmosphere one gets the net energy "loss"(this being entropic and useless energy that we don't want, and can do almost nothing with) of 4538444610000000000 joules
that's 4538444610 gigajoules

for comparison that's about the same as a gigaton nuclear bomb(heat and blast)
