The warming of the oceans by sunlight, makes the daytime surface waters more bouyant than the cooler waters below and this leads to stratification - a situation where the warmer water floats atop cooler waters underneath, and is less inclined to mix.

ENSO events, for example, can warm or cool ocean surface temperatures through exchange of heat between the surface and the reservoir stored beneath the oceanic mixed layer, and by changing the distribution and extent of cloud cover (which influences the radiative balance in the lower atmosphere).

ENSO events, for example, can warm or cool ocean surface temperatures through exchange of heat between the surface and the reservoir stored beneath the oceanic mixed layer, and by changing the distribution and extent of cloud cover (which influences the radiative balance in the lower atmosphere).

Since OHC uptake efficiency associated with surface warming is low compared with the rate of radiative restoring (increase in energy loss to space as specified by the climate feedback parameter), an important internal contribution must lead to a loss rather than a gain of ocean heat; thus the observation of OHC increase requires a dominant role for external forcing.

The current Landsea / Trenberth / Emanuel discussion has been parsed by many to mean that Landsea claims that the number of hurricanes is constant, and Trenberth is claiming that their intensity should increase as global warming heats the ocean surface.

Geoengineering proposals fall into at least three broad categories: 1) managing atmospheric greenhouse gases (e.g., ocean fertilization and atmospheric carbon capture and sequestration), 2) cooling the Earth by reflecting sunlight (e.g., putting reflective particles into the atmosphere, putting mirrors in space to reflect the sun's energy, increasing surface reflectivity and altering the amount or characteristics of clouds), and 3) moderating specific impacts of global warming (e.g., efforts to limit sea level rise by increasing land storage of water, protecting ice sheets or artificially enhancing mountain glaciers).

It seems clear to me that the ocean surface warming is being suppressed by its large heat capacity, while the land has very little heat capacity and is not being suppressed (rather than amplified).

Are the episodes thought to be actual changes in the amount of heat being radiated by the planet (because the surface of the ocean gets warmer and cooler, does the actual infrared flux from the top of the atmosphere then change as a result)?

... a pronounced strengthening in Pacific trade winds over the past two decades — unprecedented in observations / reanalysis data and not captured by climate models — is sufficient to account for the cooling of the tropical Pacific and a substantial slowdown in surface warming through increased subsurface ocean heat uptake.

Another example would be the data showing some expected warming in the surface / mid layers of the oceans as reported by Levitus et.

It is enhanced too by the formation of deep water in the polar regions, but slowed by the warming of the surface ocean.

Abstract:... Here we show that a pronounced strengthening in Pacific trade winds over the past two decades — unprecedented in observations / reanalysis data and not captured by climate models — is sufficient to account for the cooling of the tropical Pacific and a substantial slowdown in surface warming through increased subsurface ocean heat uptake.

Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differential heating.

As the area / volume ratio for the NH parts of the oceans is practically the same as for the SH, the surface heating (W / m2) must be larger in the NH parts, within the constraints of heat exchange via ocean and air currents (and partly by the difference in warming area in the tropics vs. the cooling areas in the higher latitudes)...

Also, if you look at Table T2 in this paper, you will see that ocean sea surface heat storage 0 - 700m from 1955 - 2003 (in W / m2) is always higher at northern latitudes than the corresponding southern latitudes in every case, even with the extensive Southern Ocean warming as noted by Gavin responding to ocean sea surface heat storage 0 - 700m from 1955 - 2003 (in W / m2) is always higher at northern latitudes than the corresponding southern latitudes in every case, even with the extensive Southern Ocean warming as noted by Gavin responding to Ocean warming as noted by Gavin responding to # 18.

IF cool deep sea water were mixed relentlessly with surface water by some engineering method --(e.g. lots of wave operated pumps and 800m pipes) could that enouromous cool reservoir of water a) mitigate the thermal expansion of the oceans because of the differential in thermal expansion of cold and warm water, and b) cool the atmosphere enough to reduce the other wise expected effects of global warming?

So, if each underwater artic volcano emitted 1 km3 a week (a rather large average flow) and did it for a year (about 52 weeks) you would need about 620 very active and extremely powerful volcanoes in order to warm the artic ocean by just 1 C (and that ignores surface cooling, in / out water flows and time rates that would require even more volcanoes.)

It stands to reason that the oceans haven't been that warm in a while but since the average temperature of the whole mass of water is so dependent on circulation (it's only the surface temperature that's constrained by its interactions with the atmosphere and space), I suppose a plausible history of that particular value would be very hard to reconstruct.

In many ocean models, the free surface effects are neglected and replaced by a rigid lid, yet they still get a warm pool.

The real problem here is that this AMO explanation was picked up and broadcast by the press in a very uncritical manner, usually in these terms: «Surface waters of the Atlantic ocean warm up then cool down in long, subtle cycles.

The ocean's surface begins to warm, but before it can heat up much, the surface water is mixed down and replaced by colder water from below.

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.

The mixed layer of the ocean is mixed (pretty much by definition) thus the net fluxes at the surface (latent heat, sensible heat, long wave up and down, short wave down) warm or cool the whole layer.

Albedo from medium / low level clouds warms or cools the ocean surface by increasing or decreasing over time across the global surface.

The heat from the ocean below the surface skin tends to warm the very top by convection and conduction.

These record temperatures have been assisted by a very strong El Niño event, which brought warm water to the ocean surface, temporarily warming global surface temperatures.
