Golfvirta, the thermohaline circulation
Pysähtyikö Golfvirta marraskuussa 2004 ?
During the month of November 2004, the Gulf Stream stopped for ten days. Scientists were puzzled by this behavior. Scientist Harry Bryden of the National Oceanography Center, declares, "We'd never seen anything like that before and we don't understand it. We didn't know it could happen."

described the event as "the most abrupt change in the whole [climate] record". Kiegwin adds, ""It only lasted 10 days. But suppose it lasted 30 or 60 days? ... How can we rule out a longer one next year?".
The surface and subsurface currents, the sinking regions, and the return of water to the surface form a closed loop, the thermohaline circulation or global thermohaline conveyor belt
