Oceans warmed in recent decades

But measurements show slowdown in upper-ocean heat gain since 2003

Earth’s upper ocean warmed substantially between 1993 and 2008, a new analysis reveals. The trend signals growing heat storage in oceans, researchers say, a result of human-caused warming.

CIRCUITS OVERBOARD Oceanographic data, including some collected by robotic probes like this Argo float, reveal that the uppermost 700 meters of the world’s ocean warmed substantially (about 0.18
