Peer reviewed study finds no planet warming stored in deep oceans 2005-2013, deep ocean cooled rather than warmed-Nature Climate Change

10/5/14, "The residual of those numbers implies a deep ocean cooled rather than warmed in the period from the 2005 to about 2013 and that this cooling equivalent to a decrease in sea level of −0.13 mm yr–1. The significance of this result is that it implies that the so called missing energy is not to be found in the deep ocean as many climate scientists have suggested."...subhead, "Deep ocean cooling, not warming."

10/5/14, "Scientists Find Clues to Missing Energy,"  ReportingClimateScience.com 

From Judith Curry:

"The bottom line is that uncertainties in ocean heat content are very large, and there is no particularly convincing evidence that the ‘missing heat’ is hiding in the ocean." 

"Evidence of Deep Ocean Cooling?" Climate Etc. 

Dr. Curry notes both papers released 10/5/14.

Peer reviewed study finds no evidence of warming stored in deep oceans from 2005-2013:

"Abstract"

"As the dominant reservoir of heat uptake in the climate system, the world’s oceans provide a critical measure of global climate change. Here, we infer deep-ocean warming in the context of global sea-level rise and Earth’s energy budget between January 2005 and December 2013. Direct measurements of ocean warming above 2,000 m depth explain about 32% of the observed annual rate of global mean sea-level rise. Over the entire water column, independent estimates of ocean warming yield a contribution of 0.77 ± 0.28 mm yr−1 in sea-level rise and agree with the upper-ocean estimate to within the estimated uncertainties. Accounting for additional possible systematic uncertainties, the deep ocean (below 2,000 m) contributes −0.13 ± 0.72 mm yr−1 to global sea-level rise and −0.08 ± 0.43 W m−2 to Earth’s energy balance. The net warming of the ocean implies an energy imbalance for the Earth of 0.64 ± 0.44 W m−2 from 2005 to 2013."
