David Douglass alerted me to his reply to

Dana Nuccitelli, Robert Way, Rob Painting, John Church, John Cook: 2012: Comment on “Ocean heat content and Earth’s radiation imbalance. II. Relation to climate shifts” . Physics Letters A


D.H. Douglass, R.S. Knox, 2012: Reply to “Comment on ‘Ocean heat content and Earth’s radiation imbalance. II. Relation to climate shifts’ ” by Nuccitelli et al. Physics Letters A

The first and last paragraphs of his Reply summarize with

Nuccitelli, Way, Painting, Church and Cook [1] comment on our Letter “Ocean heat content and Earth’s radiation imbalance. II. Relation to climate shifts” [2]. Their criticism is unwarranted on at least three essential grounds. (1) It is based on a misunderstanding of the climate shift concept, which is central to our Letter; (2) in making its claim of incompleteness because of neglect of the deeper ocean heat content, it ignores our statement of possible error and introduces incompatible data; (3) it over-interprets our comments about CO2 forcing. We expand on these points.

In sum, we show that the criticism of our results (change of slope in the implied FTOA at the climate shift of 2001–2002) by Nuccitelli et al. is unwarranted because they used different data of less temporal resolution. A more careful analysis of this data shows, in fact, consistency and not conflict with our results.

I recommend reading the Douglass and Knox original article, and both the Comment and Reply. The original article is

D.H. Douglass, R.S. Knox, 2012: Ocean heat content and Earthʼs radiation imbalance. II. Relation to climate shifts. Physics Letters A, Volume 376, Issue 14, 5 March 2012, Pages 1226-1229
