ATLANTIC MERIDIONAL OVERTURNING CURRENT (AMOC) AND WARMING OF THE SOUTHERN HEMISPHERE
FIGURE 14.10 The AMOC (orange arrows) transports heat from the Southern Hemisphere to the Northern Hemisphere. Climate scientists propose that large amounts of freshwater runoff in the Northern Hemisphere from melting glaciers about 19,000 years ago weakened this flow of heat-conveying water to the Northern Hemisphere, resulting in early warming of the Southern Hemisphere.
