Climate change Signs key ocean current is weakening Significant changes to the flow of the Gulf Stream may already be happening, and more sudden shifts could have severe climate impacts, finds Alec Luhn 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.
