Gulf Stream Briefing

The Gulf Stream is an ocean current that forms part of the Atlantic Meridional Overturning Circulation (AMOC). It transports heat northwards from the tropics, and is largely responsible for the relatively mild climate of Western Europe. A reduction in overturning circulation could lead to lower temperatures in the North Atlantic Ocean, which would affect the climate in Europe. Understanding the links between the climate and the Gulf Stream, and the implications of any slowing which may occur, is vital for businesses, communities and policy-makers to be able to plan for the future.

Research led by Blue-Action suggests that warmer summers in the sub-polar North Atlantic could be contributing to changes in overturning circulation. To progress further in understanding overturning circulation and how it influences Europe's weather and climate, we need to combine long-term, comprehensive observational programmes with cutting-edge model development.
