In 2007, Peter Flynn, the Poole Chair in Management for Engineers at the University of Alberta in Edmonton, Alberta, devised a US$50-billion contingency plan involving 8,000 barges that would manipulate the Atlantic conveyor, the currents of water which help ensure Northern Europe’s mild climate.

Flynn’s army of barges would maintain that mild climate in the face of global warming changing the currents and causing a deep freeze to fall over Northern Europe. The barges would float into position every fall, spraying water into the air to form ice and then pumping salt water over top and trapping it in the ice.

Come the spring, the barges would pour more water over the ice, melting it and creating a vast amount of cold, salt water that would sink, adding to and strengthening the deep current.
