    This hypothesis argues that millennial 
     | 
     | 
   
   
     | 
    oscillations were produced by the internal 
     | 
     | 
   
   
     | 
    interactions among various components of 
     | 
     | 
   
   
     | 
    the climate system. 
     | 
     | 
   
   
     | 
   
   
    | q | 
    One most likely internal interaction is the 
     | 
     | 
   
   
     | 
    one associated with the deep-water 
     | 
     | 
   
   
     | 
    formation in the North Atlantic. 
     | 
     | 
   
   
     | 
   
   
    | q | 
    Millennial oscillations can be produced from 
     | 
   
   
     | 
    changes in northward flow of warm, salty 
     | 
     | 
   
   
     | 
    surface water along the conveyor belt. 
     | 
     | 
   
   
     | 
   
   
    | q | 
    Stronger conveyor flow releases heat that 
     | 
     | 
   
   
     | 
    melts ice and lowers the salinity of the North 
     | 
   
   
     | 
    Atlantic, eventually slowing or stopping the 
     | 
     | 
   
   
     | 
    formation of deep water. 
     | 
     | 
   
   
     | 
   
   
    | q | 
    Weaker flow then causes salinity to rise, 
     | 
     | 
   
   
     | 
    completing the cycle.
