Experts voice their concerns that the Gulf Stream, that vast current of water that keeps us warm, could be cut off, leading Britain to develop a climate similar to Alaska. Our ports could be frozen over and ice storms could ravage the country. Discoveries and developments in Greenland, Russia, the Atlantic and the Arctic have fuelled fears that this climate catastrophe could happen within the next century - or even in 20 years' time.
