Climate Change Could Trigger Collapse of Major Ocean Current

The Atlantic Meridional Overturning Circulation (AMOC), a deep-sea system that circulates warm water and helps to regulate Earth's climate, is far less stable than scientists once thought, according to a new study. Under climate-change pressures such as dramatic increases in atmospheric carbon dioxide (CO2), the AMOC could even collapse entirely, resulting in a much colder Northern Hemisphere and a wetter tropical Atlantic region.
