NODC’s Pentadal Ocean Heat Content (0 to 2000m) Creates Warming That Doesn’t Exist in the Annual Data – A Lot of Warming

INTRODUCTION In the post Is Ocean Heat Content Data All It’s Stacked Up to Be?, we discussed and illustrated, for the depths of 0-700 meters, that the NODC’s pentadal ocean heat content had a significantly higher warming trend than the annual data. Refer to the discussions of Figures 5 to 7 under the heading of…

Trenberth’s missing heat still missing: new paper shows a near flat ocean temperature trend – 0.09°C over the past 55 years

A new paper published today in Geophysical Research Letters describes how the oceans have warmed only 0.09°C over the last 55 years, from 1955-2010. Don’t let the red line fool you, read on. Key Points A strong positive linear trend in exists in world ocean heat content since 1955 One third of the observed warming…

An Ocean of Overconfidence

Guest Post by Willis Eschenbach I previously discussed the question of error bars in oceanic heat content measurements in “Decimals of Precision“. There’s a new study of changes in oceanic heat content, by Levitus et al., called “World Ocean Heat Content And Thermosteric Sea Level Change (0-2000), 1955-2010″ (paywalled here). It’s highlighted over at Roger…
