Following up on the previous post: the ocean heat content data for the 0-700 meter region shows a much clearer acceleration when using the full dataset going back to 1955 -- it comes to 0.009 W/m2/yr.
It's also notable how much less variation there is in the quarterly data since the Argo buoys took over the job in 2005. (Before Argo, ocean temperatures were measured with "expendable bathythermographs" (XBTs) thrown overboard from "ships of opportunity.")
That looks better, but still waiting for the scientific article. ;-)
The early data has a large uncertainty. Thus more warming in that period (and before that period) is possible and may give very different fits.
