EARTH.COM - For over 100 years, the North Atlantic has hosted an anomaly. South of Greenland lies a patch of cool ocean water. This region, called the North Atlantic Warming Hole (NAWH), defies global warming.
Scientists long debated its cause. A new study now shows that the weakening of a vital ocean current – the Atlantic Meridional Overturning Circulation (AMOC) – explains it best.
“People have been asking why this cold spot exists,” said climate scientist Wei Liu. “We found the most likely answer is a weakening AMOC.”
