Science Mag: Earths oceans have absorbed more than 90% of the warming caused by greenhouse gases, researchers estimate, with the stored heat showing up as warmer seawater. But a new analysis suggests scientists may have underestimated the size of the heat sink in the upper ocean--which could have implications for researchers trying to understand the pace and scale of past warming.
Seas pose a formidable challenge to climate scientists. On one hand, they are as big a player in the global climate system as...
