The North Atlantic current or Gulf Stream carries warm water from the Gulf of Mexico forward Europe, providing a relative template clime in most of the European occident.
Ocean streams are sensitive to the amount of freshwater available on the surface. An increase in overflow and precipitation over the ocean could slow or revert the north Atlantic current, blocking warm water flow to Europe.
The deposition of freshwater could cause a temporal deceleration or total collapse of the North Atlantic Current, and this interruption might lead to very cold periods in the North Atlantic.
