A group of climate modelers at Lawrence Livermore and elsewhere has taken issue (in the peer-reviewed literature) with an argument made by Roger Pielke Sr. and others that the models cannot adequately explain variability in ocean temperatures:
Using simulations of 20th century climate performed with 13 numerical models, we demonstrate that the apparent discrepancy between modeled and observed variability is largely explained by accounting for changes in observational coverage and instrumentation and by including the effects of volcanic eruptions. Our work casts doubt on two recent claims: (i) that the 0- to 700-m layer of the global ocean experienced a substantial OHC decrease over the 2003 to 2005 time period and (ii) that models cannot replicate such changes. Our analysis shows that the 2003–2005 cooling is largely an artifact of a systematic change in the observing system, with the deployment of Argo floats reducing a warm bias in the original observing system.
