You may now understand why global temperature, i.e. ocean heat content, shows such a strong correlation with atmospheric CO2 over the last 800,000 years — as shown in the ice core records.

1) It seems to me that the key mechanism for any impact must be the changes that increased arctic ocean temperatures will impose on the atmospheric circulation feature known as the Polar Cell, and via this on the Ferrel cell which sits over the mid latitudes.

The first is climate inertia — on very many levels, from fossil lock - in emissions (decades), ocean - atmospheric temperature inertia (yet more decades), Earth system temperature inertia (centuries to millennia) to ecological climate impact inertia (impacts becoming worse over time under a constant stress)-- all this to illustrate anthropogenic climate change, although already manifesting itself, is still very much an escalating problem for the future.

Comparison of global lower troposphere temperature anomaly over the oceans (blue line) to a model based on the first derivative of atmospheric CO2 concentration at Mauna Loa (red line).

southern oscillation a large - scale atmospheric and hydrospheric fluctuation centered in the equatorial Pacific Ocean; exhibits a nearly annual pressure anomaly, alternatively high over the Indian Ocean and high over the South Pacific; its period is slightly variable, averaging 2.33 years; the variation in pressure is accompanied by variations in wind strengths, ocean currents, sea - surface temperatures, and precipitation in the surrounding Ocean; exhibits a nearly annual pressure anomaly, alternatively high over the Indian Ocean and high over the South Pacific; its period is slightly variable, averaging 2.33 years; the variation in pressure is accompanied by variations in wind strengths, ocean currents, sea - surface temperatures, and precipitation in the surrounding Ocean and high over the South Pacific; its period is slightly variable, averaging 2.33 years; the variation in pressure is accompanied by variations in wind strengths, ocean currents, sea - surface temperatures, and precipitation in the surrounding ocean currents, sea - surface temperatures, and precipitation in the surrounding areas

Given the context of this highly anomalous and extremely persistent atmospheric ridging over the northeastern Pacific Ocean, it's very interesting to note that there has also been a region of strongly positive sea surface temperature anomalies in same the general vicinity for the past 10 - 11 months.

It is currently suspected, for example, that the recent increase in deep - ocean heat content is driven by geothermal sources rather than atmospheric (which would solve the «paradox» that shallow ocean temperatures, over the same period, have fallen slightly).

Average air temperatures over the Arctic Ocean were much higher than normal for the month, reflecting unusual atmospheric conditions.

By examining the spatial pattern of both types of climate variation, the scientists found that the anthropogenic global warming signal was relatively spatially uniform over the tropical oceans and thus would not have a large effect on the atmospheric circulation, whereas the PDO shift in the 1990s consisted of warming in the tropical west Pacific and cooling in the subtropical and east tropical Pacific, which would enhance the existing sea surface temperature difference and thus intensify the circulation.

But matters are greatly complicated by atmospheric circulation patterns, cyclic changes in temperatures over the oceans, and the shapes of land masses.

Also, recent research has tied 20th century temperature fluctuations in northern California, and much of the Pacific Northwest, to naturally occurring atmospheric / ocean circulation patterns over the Pacific Oocean circulation patterns over the Pacific OceanOcean.

It's a mode of natural variation in the tropical eastern Pacific ocean which is indicated by sea surface temperature in that region, as well as patterns of atmospheric pressure, surface winds over the ocean, even precipitation over a much larger region.

In particular, initial stages of atmospheric model development often take place without coupling to an ocean model, running instead over observed sea surface temperatures (SSTs) and sea ice extent.

The basic point and the one relevant to climate change, is still relevant — oceans still have an enormous moderating effect on temperature over time (though if there is a huge increase or decrease in re radiated atmospheric heat it is going to then affect the oceans initially).

* Extremely high geopotential heights (a vertically aggregated measure of atmospheric temperature) over the northeastern Pacific Ocean are historically linked to very low precipitation in California.

The recent atmospheric circulation has driven near normal surface air temperatures (see Figure 7) over much of the central Arctic Ocean (normal compared to a 1981 - 2010 climatology) in the last two months.

In general, the pattern of change in return values for 20 - year extreme temperature events from an equilibrium simulation for doubled CO2 with a global atmospheric model coupled to a non-dynamic slab ocean shows moderate increases over oceans and larger increases over land masses (Zwiers and Kharin, 1998; Figure 9.29).

Scientific confidence of the occurrence of climate change include, for example, that over at least the last 50 years there have been increases in the atmospheric concentration of CO2; increased nitrogen and soot (black carbon) deposition; changes in the surface heat and moisture fluxes over land; increases in lower tropospheric and upper ocean temperatures and ocean heat content; the elevation of sea level; and a large decrease in summer Arctic sea ice coverage and a modest increase in Antarctic sea ice coverage.

They find that the different moisture availability over land and ocean leads to different atmospheric temperature lapse rates (latent heat release), which in combination with a well - mixed free (above boundary layer) atmosphere can explain the land — sea contrast.

If you have good measurements of upper ocean and atmospheric temperatures, then if you had a good decade - long satellite record of the Earth's total radiative energy balance from space — say, if Triana has been launched to in the late 1990s — then you could use conservation of energy to calculate the rate of heat uptake by the deep ocean over the past ten years.

The SST was largely irrelevant in these scenarios, as the small change in ocean temperature pales in comparison to the large change in atmospheric temperature over the land in the central US.
