Man-made heat put in oceans has doubled since 1997, study finds

shows Pacific and Atlantic meridional sections showing upper-ocean
warming for the past six decades (1955-2011). Red colors indicate a
warming (positive) anomaly and blue colors indicate a cooling (negative)
anomaly. The amount of global-warming triggered heat energy absorbed by
the seas has doubled since 1997, a new study showed. Scientists have
long known that more than 90 percent of the heat energy from man-made
global warming goes into the world's oceans instead of the ground. And
they've seen ocean heat content rise in recent years. But a new study
using ocean observing data that goes back to the British research ship
Challenger in the 1870s, includes high-tech modern underwater monitors
and computer models, tracked how much man-made heat has been buried in
the oceans in the past 150 years. (Timo Bremer/Lawrence Livermore
