Course Description

The Atlantic Meridional Overturning Circulation (AMOC) is an ocean current conveyor belt that moves the North Atlantic waters due to differences in water density. Fresh water is lighter than salt water, and as the Greenland Ice Sheet melts, more and more fresh water is entering the North Atlantic and affecting the AMOC. The AMOC has happened in the past (1,600 years ago), dramatically altering the Earth's climate. Recent scientific studies indicate that we may be entering an AMOC collapse. Learn how the AMOC works, what are the anticipated climate consequences if it should collapse, and why we should care.
