.. completed a study of the Earth's energy balance using a
combination of global climate models, ground-based
measurements, and satellite observations, and they have some
important news. Not only is Earth absorbing about 0.85 Watts
of energy per square meter more than it is radiating back to
space, but a sizable chunk of that excess energy is "hiding"
in Earth's oceans, its full effect on the climate system still
unrealized.
...precise ocean readings collected by 1,800 technology-packed
floats deployed in seas worldwide beginning in 2000, in an
international monitoring effort called Argo. The robots
regularly dive as much as a mile undersea to take temperature
and other readings.
...Significantly, greenhouse emissions have increased at a rate
consistent with the detected energy imbalance, the researchers
said.
"There can no longer be genuine doubt that human-made gases
are the dominant cause of observed warming," said Hansen,
director of NASA's Goddard Institute for Space Studies at
Columbia University's Earth Institute. "This energy imbalance
is the `smoking gun' that we have been looking for."

Oceanography said their research -- not yet published -- also
showed a close correlation between climate models and the
observed temperatures of oceans, further defusing skeptics'
past criticism of uncertainties in modeling.
