Image taken by Nasa’s Terra satellite on 7 January showing the UK covered in snow from top to toe, deep in the clutches of the current cold snap.

Britain is unusually warm for its latitude because of the Gulf Stream. This week, however, the Gulf Stream is on vacation in Greenland. So this is what Britain is like without the Gulf Stream.

Ocean currents

An unprecedented extreme in the northern hemisphere atmospheric circulation has driven a strong direct connecting current between the Gulf Stream and the West Greenland current. The unprecedented negativity of the “Arctic Oscillation” and the strong connection of the Gulf Stream with the Greenland current are exceptional events. More exceptional weather events are predicted with anthropogenic climate change, but this could be a natural variation of weather and currents.
