The continued warming of earth's atmosphere threatens to trigger a dramatic change in ocean circulation that could paradoxically plunge much of Europe and North America into bitter cold within the next few decades, oceanic expert Robert Gagosian said to a packed crowd on Friday.
Earth's oceans, which hold vastly more heat than the atmosphere, are responsible for transporting and redistributing this heat across the globe through a linked series of giant, slow-moving currents known as the "great ocean conveyor," according to Gagosian, who is President and Director of the Woods Hole Oceanographic Institute.
The Gulf Stream, which carries warm equatorial waters north, moderating the climate in Europe and the North Atlantic, is one of the best known of these currents.
