THE DAILY MAIL - Scientists from the University of California, Riverside, have warned that the Gulf Stream has been weakening for more than 100 years - and could soon collapse altogether.
The Gulf Stream is only a small part of a much wider system of currents, officially called the Atlantic Meridional Overturning Circulation (AMOC).
Described as 'the conveyor belt of the ocean', AMOC transports warm, salty water near the ocean's surface northwards from the tropics up to the northern hemisphere.
