Critical Atlantic Ocean current system is showing early signs of collapse, prompting warning from scientists | CNN

Atlantic Meridional Overturning Circulation (the AMOC) works like a giant global conveyor belt.

The currents carry heat and nutrients to different areas of the globe and play a vital role in keeping the climate of large parts of the Northern Hemisphere relatively mild.

The AMOC’s collapse could cause sea levels to surge by around 1 meter (3.3 feet).

The AMOC’s strength fluctuates, but there is no observed evidence yet of a dec Friday Hirschi says.
