so. Here's Levitus et al.2009 figure S9, showing a comparison of three different analyses of OHC from the 1950s onward. Since you think there is a problem in 2003 I've cropped the graph at 2002. The long-term multidecadal increase in OHC is obvious in all three studies. Figure S9 from Levitus et al. 2009 . Yearly time series of ocean heat content (10E+22 J) for the 0-700 m layer from this study and from Domingues et al. [2008] and Ishii and Kimoto [2008]. Linear trends for each series for 1969-2008 given in the upper left portion of the figure. Reference period is 1957-1990. You still haven't given any evidence that pre-ARGO OHC data are "unreliable". Since that claim contradicts the results of multiple peer-reviewed studies showing long-term increases in OHC, one would demand very convincing evidence, but you provide no evidence at all, merely assertions. I think we can conclude that the oceans have in fact been warming over the past half-century. This should be no surprise, since oceans cover more than half the planet, and the surface and atmosphere are also warming. Bernyi Pter pardon me for butting in but you're not the only person remarking on year 2003 as appearing as some sort of wild excursion. However, if you look at the data you that 2003 simply marks the onset of three years of temperature upticks. Looking at the rest of the graph, I don't see anything unusual about these years other than we see three upswings in
