Kevin E. Trenberth reports in Nature that "The warming ocean is revealed by changes in heat content from 1993 to 2008, shown by the black line with error bars, as constructed by Lyman et al.1. This analysis samples the ocean to 700 m depth and gives an average warming trend of 0.64 W m−2 (red line). The data available from Argo floats since 2003 enable an estimate to 2,000 m depth (blue line)8 to be made. The differences between the black and blue plots after 2003 suggest that there has been significant warming below 700 m, and that rates of warming have slowed in recent years. Processing of the two data sets is not compatible, however, so firm conclusions cannot yet be drawn by comparing them."
