  • Temperatures in the North Atlantic are influenced by a giant 'conveyor belt' of warm water from the south called the meridional overturning circulation.

    A natural stop to global warming....

  • The currents are driven by a “conveyor belt” mechanism, known as the meridional overturning circulation, that depends on salinity to keep it running: as water from the warm Gulf moves northward, it evaporates moisture to the colder atmosphere, which increases the ocean water salinity and thus its density; the denser water sinks and flows back southward, where the cycle begins anew.
