Lab Notes: What happens if a major ocean current … stops?

The Atlantic Meridional Overturning Circulation (AMOC) is a vast current that helps move water and energy right around our planet, from top to bottom. Scientists say it is slowing down — and might stop altogether, with dire consequences for the global climate if it does. So how do major ocean currents work, why is it slowing down, and what will happen if it collapses?
