UN IPCC climate report casts doubt on claims that global warming is hiding in oceans, says computer model simulations of oceans absorbing heat have errors and are unreliable-Chapter 8

"These errors in oceanic heat uptake will also have a large impact on the reliability of the sea level rise projections."

"Climate Change 2007: Working Group I: The Physical Science Basis"
. 
"8.3.2.2.2 Southern Ocean circulation"

"The Southern Ocean wind stress error has a particularly large detrimental impact on the Southern Ocean simulation by the models. Partly due to the wind stress error identified above, the simulated location of the Antarctic Circumpolar Current (ACC) is also too far north in most models (Russell et al., 2006). Since the AAIW is formed on the north side of the ACC, the water mass properties of the AAIW are distorted (typically too warm and salty: Russell et al., 2006). The relatively poor AAIW simulation contributes to the multi-model mean error identified above where the thermocline is too diffuse, because the waters near the base of thermocline are too warm and salty.

It is likely that the relatively poor Southern Ocean simulation  

will influence the transient climate response to increasing greenhouse gases by affecting the oceanic heat uptake. 

When forced by increases in radiative forcing, models with too little Southern Ocean mixing will probably underestimate the ocean heat uptake; models with too much mixing will likely exaggerate it. 

These errors in oceanic heat uptake will also have a large impact on the reliability of the sea level rise projections. See Chapter 10 for more discussion of this subject."

=======================

Subsequent UN IPCC chapter again cites inability of computer models to measure ocean heat:

"8.3.2.3 Summary of Oceanic Component Simulation"

"In the Southern Ocean, the equatorward bias of the westerly wind stress maximum found in most model simulations is a problem that may affect the models’ response to increasing radiative forcing."
