The North Atlantic Ocean's Missing Heat Is Found in Its Depths

Cody Sullivan by C. Sullivan 3 March 201612 January 2022

In the 2000s, the North Atlantic stopped absorbing as much atmospheric warmth. However, the ocean lost only a little heat—the rest was held deeper below the surface by altered circulation patterns.
