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.

In 2008, climate
change sceptic Roger Pielke Sr said this: «Global warming, as diagnosed by upper
ocean heat content has not been occurring
since 2004».
The key observation here is the increase in
ocean heat content over the last half century (the figure below shows three estimates of the
changes since 1955).
More than 95 % of the 5 yr running mean of the surface temperature
change since 1850 can be replicated by an integration of the sunspot data (as a proxy for
ocean heat content), departing from the average value over the period of the sunspot record (~ 40SSN), plus the superimposition of a ~ 60 yr sinusoid representing the observed oceanic oscillations.
In Balmaseda et al. paper, they show very nicely the
changes in the
ocean heat content (OHC)
since the late 1950s and how during the last decade the OHC has substantially increased in the deep
ocean while in the first 300 and 700 meters it has stalled.
I guess from the diference between
ocean heat content over freezing point as opposed to the OHC
change since 1970?
The 2009 State of the Climate Report of the US National Oceanic and Atmospheric Administration (NOAA) tells us that climate
change is real because of rising surface air temperatures
since 1880 over land and the
ocean,
ocean acidification, sea level rise, glaciers melting, rising specific humidity,
ocean heat content increasing, sea ice retreating, glaciers diminishing, Northern Hemisphere snow cover decreasing, and so many other lines of evidence.

The upper figure shows
changes in
ocean heat content since 1958, while the lower map shows
ocean heat content in 2017 relative to the average
ocean heat content between 1981 and 2010, with red areas showing warmer
ocean heat content than over the past few decades and blue areas showing cooler.
I inferred from your statement that
since the
heat capacity of the atmosphere is small compared to «say, the
oceans» that (a) it [the atmosphere] won't store much energy, and (b) as such won't
change the total «
heat content» of the Earth, and (c) as such won't
change the Earth's temperature.

Slow variations in upper
ocean heat content that have been observed in the subpolar and marginal ice zone regions of the Atlantic
since the mid-twentieth century are thought to be related to
changes in the strength of the Atlantic Meridional Overturning Circulation (AMOC).
• Lyman, J. M., and G. C. Johnson, 2014: Estimating Global
Ocean Heat Content Changes in the Upper 1800 m

Other data sets such as
ocean heat content, sea ice extent, whatever, are not sufficiently mature or long - range... Further, the surface temperature is most relevant to climate
change impacts,
since humans and land ecosystems live on the surface.»
In my opinion, measuring the
heat content of the
oceans can not necessarily be used to assess sensitivity
since a slight
change in the amount of cloudiness has a significant impact on the amout of solar radiation being received by the
oceans.
