Willis Eschenbach has posted an article on Anthony Watts' WUWT blog. He's wondering this time about ocean heat and forcing. He's done something similar to what Bob Tisdale did a little while ago and wrote about here.
Here is Willis' chart. Willis has done some sums on ocean temperature and plotted this chart in units of watts/sq metre. Willis calculated from scratch and may not have got the conversion ratios quite right. I didn't check. I do know that it's not that easy to work out the specific heat of sea water going all the way down to two kilometres deep into the ocean.
How Anthony Watts is tricked...

Hmmm, this rather puts the kibosh on this graph from the SkS zealots:
Makes me wonder how Murphy finds such a large trend in OHC, but Levitus does not find any trend in forcing.
[REPLY: Thanks, Anthony. There is a large trend in OHC, as you show in your graph, but it is not statistically significant. This is because of the high autocorrelation of the data (lag-1 autocorrelation of 0.92). As usual, SkS forgot to mention that ... w.].I'm not about to check that out but will just observe that the standard errors quoted by NOAA are much lower than the heat content reported. SkepticalScience has links to relevant papers, but they are behind a paywall. It's certain that the ocean is heating up (sea levels are rising etc) just as it's certain the oceans are getting more acidic.
Small mercies. I suppose Willis could have denied it was warming altogether or put it down to one of Bob Tisdale's magical ENSO leaps.
Thanks to Dana, here is the up-to-date SkepticalScience.com chart showing how heat is accumulating on Earth:
