A newly discovered deep, cold current flowing off Iceland's coast may reveal that the North Atlantic is less sensitive to climate change than previously thought, researchers report. The new current, the North Icelandic Jet, feeds the Atlantic Meridional Overturning Circulation, a giant pattern known as the "great ocean conveyor belt." Because this pattern is critically important for regulating Earth's climate, including European and North American climates, any strong influences on it, and their response to a warming Earth, are of keen scientific and practical interest.
