Models show that as the Atlantic Meridional Overturning Circulation gets weaker, the Gulf Stream will drift northwards. There are signs that this is already happening, and a more abrupt shift could warn of more severe climate impacts

A gradual northward shift in the Gulf Stream has provided more evidence that the system of currents that keeps Europe warm is weakening. What’s more, modelling suggests that any abrupt shift in the Gulf Stream could signal an imminent, catastrophic collapse in the ocean current.
