Atlantic Ocean circulation at weakest in a millennium, say scientists

Decline in system underpinning Gulf Stream could lead to more extreme weather in Europe and higher sea levels on US east coast

The Atlantic Ocean circulation that underpins the Gulf Stream, the weather system that brings warm and mild weather to Europe, is at its weakest in more than a millennium, and climate breakdown is the probable cause, according to new data.

Further weakening of the Atlantic Meridional Overturning Circulation (AMOC) could result in more storms battering the UK, more intense winters and an increase in damaging heatwaves and droughts across Europe.
