A decade into the 21st century, scientists have confirmed the existence of a new and apparently crucial ocean current on the face of the Earth. The current, called the North Icelandic Jet, is not merely a curiosity. Though relatively narrow, it is an important cog in the global oceanic conveyor of currents that transports equatorial heat to the North Atlantic region and tempers its climate. Learning how the current operates offers insights into potential monkey wrenches that could disrupt ocean circulation and lead to further climate changes.
