In all our results, we use a sampling strategy that compares model and observations only where observations exist; we do not use the infilled or interpolated data set ( 11 ). As a test, however, we repeated the analysis using the infilled data and found that it made no difference to the conclusions. More details on these sampling issues are found in ( 16 ). We also estimated the impact that model errors might have on the results. Multiple models run with the same GHG forcing ( 25 ) show a factor of 2 dif- ference in ocean basin heat content after 80 years of integration ( 26 , 27 ). We estimated the effect that this had in the detection scheme and still found robust detection results above the level of natural variability ( 16 ). Therefore, the conclusion that the observed ocean warming is due to human influences is robust to major perturbations of both the observed data set and model error....
