It's a bit worrying that his conclusions rest rather heavily on the Levitus ocean heat content data. Steve does not seems to recognize the rather large uncertainties inherent in Levitus (see, e.g., Krishna's recent paper in PNAS, which I'm appending). Recent work by John Church and colleagues (which attempts to adjust ocean temperature data and heat content estimates for some of the instrumental biases identified by Gouretski and Koltermann) suggests that Levitus may have underestimated the true increase in ocean heat content over the 20th century. I'm not sure whether I'm going to the Indianapolis CCPP meeting. I'm feeling kind of burned out after our five-year external review, and lots of lecturing over the past few months. But if I don't go, I'm going to have to prepare a poster, which I also dislike doing! I'll let you know soon.
