This is at least ten additional years compared to the majority of previously published studies that have used the instrumental record in attempts to constrain the ECS.We show that the additional 10 years of data, and especially 10 years of additional ocean heat content data, have significantly narrowed the probability density function of the ECS.

For example, as discussed in Nuccitelli et al. (2012), the ocean heat content data set compiled by a National Oceanographic Data Center (NODC) team led by Sydney Levitus shows that over the past decade, approximately 30 percent of ocean heat absorption has occurred in the deeper ocean layers, consistent with the results of Balmaseda et al. (2013).

So where do all these graphs showing global heat content that include the heat hiding in the deep ocean come from?

Since the IPCC's graph above up to 2003 shows that most of the energy from global warming is in the oceans, to a first approximation, Ocean Heat Content change since then is going to be close enough to the Total Heat Content change.

This map shows trends in global ocean heat content, from the surface to 2,000 meters deep.

Gavin, I think it would be worth adding to the post 1) the main reason why there was so much doubt about the Lyman et al results (the unphysical melt amounts for 2003 - 5), 2) the expected role of GRACE in obtaining a reliable result, 3) the fact that the ARGOs don't measure the deep oceans, and 4) that it's inappropriate to take the remaining ARGO data (shown in the Lyman et al correction to be essentially flat for the last two years) and draw any conclusions about ocean heat content trends for that period.

Ocean Heat Content estimates produced by the ex-NODC at NCEI show that OHC anomalies in each quarter of 2015 were the highest on record for each quarter.

For example, additional evidence of a warming trend can be found in the dramatic decrease in the extent of Arctic sea ice at its summer minimum (which occurs in September), decrease in spring snow cover in the Northern Hemisphere, increases in the global average upper ocean (upper 700 m or 2300 feet) heat content (shown relative to the 1955 — 2006 average), and in sea - level rise.

Balmaseda et al. (2013) suggested that changes in the winds have resulted in a recent heat accumulation in the deep sea that has masked the surface warming and that the ocean heat content shows a steady increase.

As for ocean heat content, Argo hasn't been in the water long enough to show a clear signal, and there have been problems with the data, including a significant correction (you do recall the correction to the UAH satellite record after years of insistence that their data showed the surface temp record trends were completely wrong?).

I'm not as well read on this subject as I would like but I know that Dr Craig Loehle has recently completed a study of the ocean heat content anomaly data compiled by Willis et al (2008b), his findings show that since the Argo array of profiling floats programme began taking accurate measurements in 2003, that the ocean has been cooling during the period 2003 — 2008.

Several independent analyses of hundreds of thousands of measurements show that the ocean heat content began a steady rise in the 1970s.
