Scientists have uncovered more evidence for a dramatic weakening in the
vast ocean current that gives Britain its relatively balmy climate by
dragging warm water northwards from the tropics. The slowdown, which
climate modellers have predicted will follow global warming, has been
confirmed by the most detailed study yet of ocean flow in the Atlantic.
Most alarmingly, the data reveal that a part of the current, which is
usually 60 times more powerful than the Amazon river, came to a
temporary halt during November 2004.
