I am also curious about what would cause the proposed increased heat content of the oceans to «come out» and thus warm the climate. (skepticalscience.com)
The time series shows an overall trend of increasing heat content in the World Ocean with interannual and inter-decadal variations superimposed on this trend. (ipcc.ch)
The authors note that more than 85 % of the global heat uptake (Q) has gone into the oceans, including increasing the heat content of the deeper oceans, although their model only accounts for the upper 700 meters. (skepticalscience.com)
