Summary

Story summary

Researchers found a persistent cold water and air anomaly south of Greenland.
Data back to 1955 show the cooling stems from reduced warm-water inflow, indicating a weakening Atlantic Meridional Overturning Circulation.
ARGO floats show the Gulf Stream shifting off U.S. coast.
Models and researchers predict an AMOC collapse would cool UK, raise sea levels along seaboard, disrupt monsoons, and warn the AMOC nears a tipping point that could trigger collapse.
