Atlantic Meridional Overturning Circulation (AMOC) is slowing down, raising the possibility of its collapse, which could lead to significant temperature drops in the UK and Scandinavia.

A recent study indicates the Atlantic Meridional Overturning Circulation (AMOC), a crucial ocean current transporting warm water towards the Arctic, is slowing down, raising the possibility of its collapse this century. The AMOC's collapse could lead to a drop of 5-15°C in temperatures in the UK and Scandinavia within decades. Past changes in AMOC have had significant impacts on New Zealand's climate, and the study suggests that a future collapse could accelerate ongoing warming trends in the region, with potential global consequences.
