Ocean Warming Data

I have several times seen the claim that, despite the apparent pause in surface temperatures, global warming is actually going faster than ever, with the missing heat in the ocean. So far I have seen no support for that claim. I did, however, recently come across an article discussing global heat content changes and problems in estimating them that contains an interesting graph.

As best I can tell, the different lines represent different ways of estimating the values, given the data limitations, with data becoming available later for the deeper depths; the vertical lines show, for each depth, the date when global coverage reached 50%. So the bottom graph is the best in terms of how deep it goes, the worst in quality of the data.

The  pattern seems pretty clear. Slow warming until about 1996, faster from then until about 2004, slower to zero warming thereafter.
