Versiegender Golf-Strom
Among the greatest fears scientists have about global warming is that it will cause the massive ice fields of Greenland and other locales at the northern end of the Gulf Stream to melt rapidly, sending surges of cold water into the ocean system and interrupting the flow of the Ocean Conveyor Belt.
One doomsday scenario is that such an event would stop or disrupt the whole Ocean Conveyor Belt system, plunging Western Europe into a new ice age without the benefit of the warmth delivered by the Gulf Stream.
