[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?)

With the current GHG content in the atmosphere, more solar energy arrives than leaves via radiation -LRB-.85 + / -.15 Watt / m ^ 2), which raises the heat content of the terrestrial system, i.e., the average temperature over the whole earth + oceans + atmosphere.

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.

I also used my implementation to break up a quick land response from a slow ocean response to see if the change in sign of the derived temperature derivative coming at a place where it is not intersecting the instantaneous temperature might be explained by the derived temperature being an average.

Given all the independent lines of evidence pointing to average surface warming over the last few decades (satellite measurements, ocean temperatures, sea - level rise, retreating glaciers, phenological changes, shifts in the ranges of temperature - sensitive species), it is highly implausible that it would lead to more than very minor refinements to the current overall picture.

As the distribution of land and ocean areas in the two hemispheres is markedly different the redistribution of heat via MOC leaves open the possibility of the world getting hotter in the first sense whilst the averaged temperatures only rise a little or stagnate.

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.
