I didn't keep the links but there is at least one d18O study from the Pacific Warm Pool which clearly indicates that first the deep ocean warmed there, followed later by the CO2 increase and then the shallow ocean warmed, leading to the LGM to Holocene transition.

Long continuous records of temperature and salinity at Ocean Weather Station M in the Norwegian Sea indicate that the deep water has also warmed noticeably.

Their argument goes like this: It is not possible that warming of the deep ocean accelerates at the same time as warming of the upper ocean slows down, because the heat must pass through the upper layer to reach the depths.

Second, physically there is absolutely no problem for wind changes to cool the upper ocean at the same time as they warm the deeper layers.

@ 48 If your speculation is correct, I assume that another consequence would be that, if / when concentrations of greenhouse gases start to drop, corresponding reductions in surface ocean / land temperatures would take place at a much slower rate than would otherwise be the case: the surplus heat stored in the deep ocean will gradually make its way to the ocean surface, and continue to warm the atmosphere for decades, if not longer.

If in exceeds out and the diffential MUST exist from top to bottom of the atmosphere, then before the hotter air can migrate to the deep ocean, the daily temerature cycling will force the hotter air at the bottom into an overall equlibrium ie hotter air will rise — or more correctly since GHGs have heated the air up more at the bottom, then the sun induced daily warming will add more heat to the top, & less at the bottom to force the equilibrium — ie effectively hot air rising even if not in actuality.

But as cogently interpreted by the physicist and climate expert Dr. Joseph Romm of the liberal Center for American Progress, «Latif has NOT predicted a cooling trend — or a «decades - long deep freeze» — but rather a short - time span where human - caused warming might be partly offset by ocean cycles, staying at current record levels, but then followed by «accelerated» warming where you catch up to the long - term human - caused trend.

Both Judith Curry and Gavin Schmidt have acknowledged that even if Trenberth is right about global warming being sequestered in the deep ocean it doesn't matter because that sequestered heat can not undilute itself to warm the atmosphere quickly — it comes out over a 10x longer period at 1 / 10th the orginal power i.e. what when in at 0.5 W / m2 in a decade comes out at 0.05 W / m2 over a century which is insignificant.
