Since most of our ocean sensors are on the surface, and «ocean temperature» is often used as shorthand for «ocean surface temperature», it seems to me that we should see the oceans warming at least as fast as the land, if internal ocean variability could explain global warming.

Since then there are a number of papers published on why the warming was statistically insignificant including a recent one by Richardson et al. 2016 which tries to explain that the models were projecting a global tas (temperature air surface) but the actual observations are a combination of tas (land) and SST oceans, meaning projected warming shouldn't be as much as projected.

There is a major question in my mind of the wisdom of using a «global» surface temperature to begin with and a «global» surface temperature based on a SST which is more related to Tmin averaged with a land based «Surface» temperature that is based on T Ave.. So instead of blindly quoting nonsense, I actually try to verify using all the data that is avasurface temperature to begin with and a «global» surface temperature based on a SST which is more related to Tmin averaged with a land based «Surface» temperature that is based on T Ave..
