Projected Change in Atlantic
Meridional Overturning Circulation (MOC)
§  The MOC is an indicator
of ocean circulation
changes in response to
global warming.
§  The MOC is projected to
slow down in the future.
§  It is due to the warming
and increased
precipitation at higher
latitudes.
§  The weakened MOC will
help to reduce global
warming at higher latitude,
because less heat will be
transported there.
