...dense) water flows underneath the Gulf Stream as it moves from the tropics to the North Atlantic. When this salty stream reaches the far north, it is forced to the surface as water above it is blown aside by the winds; it then discharges its tropical heat into the arctic air, cools off and sinks to the bottom, where it returns to the tropics to be heated again...
...this current, argue Broecker and Denton, that keeps the Arctic relatively warm and glacier free. When it stops running, an ice age -- or a cold spike -- begins. What causes a turnoff? An influx of fresh water might do it, by diluting the saltiness and density of the current, preventing it from sinking and heading back to the tropics.

The discharge stopped about 1,000 years later...
