Atlantic Meridional Overturning Current
What is the issue? Atlantic Meridional Overturning Current (AMOC) is thought to be slowing down for the last 15 years, which could have drastic consequences on global climate. But new study suggests that AMOC is getting help from the Indian Ocean. What is an AMOC? Atlantic Meridional Overturning Current is the large system of ocean currents operating in the Atlantic Ocean which circulates the waters between the north and the south. It ensures the oceans are continually mixed, and heat and energy are distributed around Earth. Warming as a result of climate change, the Indian Ocean is causing a series of cascading effects. How AMOC works? As warm water flows northwards in the Atlantic, it cools, while the evaporation increases its salt content. The cold, dense water deep below slowly spreads southward. Eventually, it gets pulled back to the surface and warms again and, the circulation is complete. This continual mixing of the oceans, and distribution of heat and ener
