But if something causes heat to be transferred from the ocean surface into its deeps more rapidly than usual, ocean surface temperatures could rise more slowly, not rise at all, or even fall despite the increased backradiation.
Dr. Roz Pidcock, PhD in physical oceanography from the University of Southampton (http://www.carbonbrief.org/blog/2014/10/an-in-depth-look-at-the-oceans-climate-change-and-the-hiatus/): «Over the last 15 years or so, surface temperatures have risen much slower than in previous decades, even though we're emitting greenhouse gases faster than we were before.»
The famous «255 K» value for no greenhouse effect on Earth is an example of this, although in reality if we got that cold you would expect a snowball - like Earth and a much higher albedo from the increased brightness of the surface... and thus the «no - greenhouse temperature» would be even colder than 255 K.
If not for the temperature discontinuity, then the radiation coming from the surface would be less than what fits the linear T ^ 4 pattern, with the biggest difference at angles near vertical.
Before allowing the temperature to respond, we can consider the forcing at the tropopause (TRPP) and at TOA, both reductions in net upward fluxes (though at TOA, the net upward LW flux is simply the OLR); my point is that even without direct solar heating above the tropopause, the forcing at TOA can be less than the forcing at TRPP (as explained in detail for CO2 in my 348, but in general, it is possible to bring the net upward flux at TRPP toward zero but even with saturation at TOA, the nonzero skin temperature requires some nonzero net upward flux to remain — now it just depends on what the net fluxes were before we made the changes, and whether the proportionality of forcings at TRPP and TOA is similar if the effect has not approached saturation at TRPP); the forcing at TRPP is the forcing on the surface + troposphere, which they must warm up to balance, while the forcing difference between TOA and TRPP is the forcing on the stratosphere; if the forcing at TRPP is larger than at TOA, the stratosphere must cool, reducing outward fluxes from the stratosphere by the same total amount as the difference in forcings between TRPP and TOA.
If the surface temperature is slow to catch up to that imbalance then the energy imbalance remains large, and we can have sufficient net heating to cause much faster changes in the ice sheets than from the comparatively smaller imbalances caused by the changes in Earth's orbit associated with the glacial periods in the past.

If a significant fraction of this heat lost from the ocean went into the atmosphere one might have expected the surface air temperature to have increased faster during this period than during the subsequent period of the 1990s when the ocean heat content gained > 5 X 10 ^ 22 J, but this is not what was observed (see reference Figure 2.7 c in the IPCC TAR Working group I).

This means that the «pause,» or whatever you want to call it, in the rise of global surface temperatures is even more significant than it is generally taken to be, because whatever is the reason behind it, it is not only acting to slow the rise from greenhouse gas emissions but also the added rise from changes in aerosol emissions.

That warming on descent also reduces the rate of temperature decline with height which suppresses convection from the surface so that the surface on the day side then warms more than it otherwise would have done and the surface on the night side cools less quickly than it otherwise would have done..
