Atlantic Meridional Overturning Circulation (AMOC) is an ocean current
It redistributes warm water throughout our planet's oceans
This also moves warm water from Gulf of Mexico to the North Atlantic
However, a new study finds it is weakening, which would disrupt our climate
Sea levels along the east coast could rise if AMOC slows and comes to a halt
Analysis of its strength shows it has weakened dramatically since the 1950s
