'Our model shows that water from the Agulhas current affects currents in the north Atlantic much faster than previously thought. Changes in the Agulhas current should be noticeable in currents thousands of miles north of it,' explains team leader Arne Biastoch.

The Gulf Stream carries warm water from the tropics to Europe, releasing its heat into the air. The cool water then flows back south, where it warms up and starts the cycle again.

'This research shows that we need more understanding of how ocean currents affect each other to predict the future climate, and more importantly monitor the effect of global warming,' explains Gulf Stream expert Torsten Kanzow.
