It is ironic that one consequence of global warming is that Europe might plunge into a deep freeze. This possibility stimulated an unusual research project at the University of Alberta. Dr. Peter Flynn, the Poole Chair in Management for Engineers in the U of A Department of Mechanical Engineering, has studied whether down-welling ocean currents can carry more dissolved carbon into the deep ocean. He learned they can't, but in the course of this research he found some evidence that the ocean currents that bring warm water to the oceans off northern Europe may be weakening. The results of the...
