[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?)

The standard assumption has been that, while heat is transferred rapidly into a relatively thin, well - mixed surface layer of the ocean (averaging about 70 m in depth), the transfer into the deeper waters is so slow that the atmospheric temperature reaches effective equilibrium with the mixed layer in a decade or so.

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.

The average temperature of all the oceans water is about 4c compared to the average of 17 / 18c for just the surface layer.

«As a coastal city located on the tip of a peninsula, San Francisco is vulnerable to sea level rise, and human activities releasing greenhouse gases into the atmosphere cause increases in worldwide average temperature, which contribute to melting of glaciers and thermal expansion of ocean water — resulting in rising sea levels,» the ordinance reads.

It seemsthe observed increase in trade winds lead to the surfacing of cooler waters in the Eastern Pacific ocean and this phenomenon is found by models to cause global average temperatures to cool.

Since 4C is about the average of the deep ocean, more cooling on one side or the other of the convergence zone changes the average temperature of the sinking water.

The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; [4] its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities.

Pritchard noted that the Antarctic Peninsula's annual average air temperature has risen 5.4 degrees Fahrenheit (3 degrees Celsius) since 1950, while near - surface ocean waters have warmed 1.8 degrees Fahrenheit (1 degree Celsius).

Another problem, as has been mentioned before, is that about 98 % of anthropogenic CO2 should be absorbed by the oceans in order to preserve the 1:50 partitioning ratio of CO2 between air and water at earth's average surface temperature that is governed by Henry's law.

The average temperature of the ocean is down around 4C, so there's a general propensity for heat to transfer downwards in the water.

It is not «conduction» but exchange of radiation; if you keep your hands parallel at a distance of some cm the right hand does not (radiatively) «warm» the left hand or vice versa albeit at 33 °C skin temperature they exchange some hundreds of W / m ² (about 500 W / m ²) The solar radiation reaching the surface (for 71 % of the surface, the oceans) is lost by evaporation (or evapotranspiration of the vegetation), plus some convection (20 W / ²) and some radiation reaching the cosmos directly through the window 8µm to 12 µm (about 20 W / m ² «global» average); only the radiative heat flow surface to air (absorbed by the air) is negligible (plus or minus); the non radiative (latent heat, sensible heat) are transferred for surface to air and compensate for a part of the heat lost to the cosmos by the upper layer of the water vapour displayed on figure 6 - C.

Each layer of water in the ocean has vastly different temperatures, so determining the average temperature is nearly impossible without glossing over important data.

ANSWER: There is not «A» temperature of the oceans but a constantly changing distribution of temperatures and of partial pressures of the gases; figure 17 - D from the Publications Office of the European Union gives a global view with some time averaging: it is anywhere between 280 µatm and 430 µatm in the water!

If there is deep - water formation in the final steady state as in the present day, the ocean will eventually warm up fairly uniformly by the amount of the global average surface temperature change (Stouffer and Manabe, 2003), which would result in about 0.5 m of thermal expansion per degree celsius of warming, calculated from observed climatology; the EMICs in Figure 10.34 indicate 0.2 to 0.6 m °C — 1 for their final steady state (year 3000) relative to 2000.

Even if the temperature e.g. at the poles, the sink places, dropped 1 °C more than average, that doesn't make much difference: the current CO2 level at about 400 ppmv gives about the same partial pressure of 400 microatm everywhere over the oceans (minus a few % due to water vapour).

In the Arctic, due to colder - than - average water temperatures, only about 200 m of water depth is required, which increases the vulnerability of those methane hydrates to a warming Arctic Ocean.

For global average sea level, the main control on water density over these times is ocean temperature, with warming causing thermal expansion by roughly 0.4 m per degree C (Levermann et al., 2013).

As the Earth's surface cools further, cold conditions spread to lower latitudes but polar surface water and the deep ocean can not become much colder, and thus the benthic foraminifera record a temperature change smaller than the global average surface temperature change [43].

Without this greenhouse effect, the average surface temperature would be 255 degrees kelvin -LRB--18 degrees Celsius or 0 degrees Fahrenheit); a temperature so low that all water on Earth would freeze, the oceans would turn into ice and life, as we know it, would not exist.
