The observed fact that temperatures increases slower over the oceans than over land demonstrates that the large heat capacity of the ocean tries to hold back the warming of the air over the ocean and produces a delay at the surface but nevertheless the atmosphere responds quit rapidly to increasing greenhouse gases.

In a transient situation (such as we have at present), there is a lag related to the slow warm up of the oceans, which implies that the temperature takes a number of decades to catch up with the forcings.

As it does so, it oxidises to CO2, dissolving in seawater or reaching the atmosphere as CO2 which causes far slower warming, but can nevertheless contribute to ocean acidification.

As the globe warms, the slow rise in ocean levels has caused great concern.

[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in equilibrium with water / ice, would precipitate out if not for the CO2, so acts as a feedback; since the oceans cover so much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)

Guemas et al. (Nature Climate Change 2013) shows that the slower warming of the last ten years can not be explained by a change in the radiative balance of our Earth, but rather by a change in the heat storage of the oceans, and that this can be at least partially reproduced by climate models, if one accounts for the natural fluctuations associated with El Niño in the initialization of the models.

This recent slower warming in the upper ocean is closely related to the slower warming of the global surface temperature, because the temperature of the overlaying atmosphere is strongly coupled to the temperature of the ocean surface.

If it would warm 5 degrees this century, which seem quite possible, that would be about 100 times faster than the average rate during the last deglaciation, although I suppose ocean heat content rises somewhat slower.

However, the ocean is very strongly stratified, and the interaction with the bulk of the deep cold water is very slow — it is generally the upper ocean that determines the time scale for the transient warming we might expect.

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.

The oceans are warming now but they are still a CO2 sink (hence acidification), even if the rate is slowing.

Given that the cryosphere and oceans are far better long - term indicators of changes in Earth's energy balance than the much more «noisy» troposphere, for anyone to suggest that the warming of the Earth system has slowed or stopped over the past 10 years, means they are purposely ignoring the far bigger heat sinks of the cryrosphere and oceans, or they simply want to spout nonsense.

That the heat absorption of the ocean as a whole (at least to 2000 m) has not significantly slowed makes it clear that the reduced warming of the upper layer is not (at least not much) due to decreasing heating from above, but rather mostly due to greater heat loss to lower down: through the 700 m level, from the upper to the lower layer.

With even further warming more hydrates are released, additional global soil feedback (extreme soil respiration rates, compost bomb instability) and weathering becomes a driver, now Ocean very stratified, maybe things like permanent El Nino, weather systems probably move very slow — everything gets stuck due to lack of perturbed ocean, no or very little frozen water at the pOcean very stratified, maybe things like permanent El Nino, weather systems probably move very slow — everything gets stuck due to lack of perturbed ocean, no or very little frozen water at the pocean, no or very little frozen water at the poles.

@ 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.

Vertical diffusion is slower, but happens over most of the oceans, while downward advection of anomalously warm water happens in fewer spots but is faster (the North Atlantic, «Mode» water formation regions north of the Antarctic Circumpolar Current, shelf water formation in Antarctica).

In a transient situation (such as we have at present), there is a lag related to the slow warm up of the oceans, which implies that the temperature takes a number of decades to catch up with the forcings.

The latter brings a somewhat slower warming at the surface of our planet, because more heat is stored deeper in the ocean.

For example: 1) plants giving off net CO2 in hot conditions (r / t aborbing)-- see: http://www.climateark.org/articles/reader.asp?linkid=46488 2) plants dying out due to heat & drought & wild fires enhanced by GW (reducing or cutting short their uptake of CO2 & releasing CO2 in the process) 3) ocean methane clathrates melting, giving off methane 4) permafrost melting & giving off methane & CO2 5) ice & snow melting, uncovering dark surfaces that absorb more heat 6) the warming slowing the thermohaline ocean conveyor & its up - churning of nutrients — reducing marine plant life & that carbon sink.

Until we clear up whether there has been some kind of accelerated warming at depth in the real ocean, I think these results serve as interesting hypotheses about why the rate of surface warming has slowed - down, but we still lack a definitive answer on this topic.
