Increasing heat content of the global ocean dominates the energy imbalance in the climate system. Here we show that ocean heat gain over the 0–2,000 m layer continued at a rate of 0.4–0.6 W m−2 during 2006–2013. The depth dependence and spatial structure of temperature changes are described on the basis of the Argo Program's2 accurate and spatially homogeneous data set, through comparison of three Argo-only analyses.
