Sea level rise has two primary components: the expansion in volume of seawater with increased temperature and the addition of water in ocean basins from the melting of land - locked ice, including Antarctica and Greenland.

As the ocean warms, for example, it releases CO2 to the atmosphere, with one principal mechanism being the simple fact that the solubility of CO2 decreases as the water temperature rises [204].

Marshes, wetlands and peat bogs account for the greatest source of naturally produced methane, with unknown quantities locked in the soil of permafrost and the ocean floor that may be released as world temperatures rise.

With water pollution and temperatures on the rise, toxic algae cause serious problems nowadays for inland waters and for the oceans.

The physics part is that to first order, you expect the rate of continental ice melt to increase with temperature, and also the rate at which heat penetrates into the ocean below the mixed layer (for the mixed layer indeed we use a term relating temperature to sea level, not its rate of rise).

The new GSL statement outlines evidence that a relatively modest rise in atmospheric CO2 levels and temperature leads to significant sea level rise, with oceans more acidic and less oxygenated.

After all, if average surface temperature is 15 C, wouldn't you expect land and ocean below the surface to equilibrate at roughly that temperature (with a slightly rising gradient to account for the flow of Earth's internal heat)?

However the ocean temperatures are not recently rising (the ARGO data set), and a strong and consistent trend should be observable with consistent CO2 increase.

This recovered role may be especially important as climate change threatens ocean ecosystems with rising temperatures and acidification.

And guaranties that the cited above G8 deal is dead on arrival... Not that the deal will change anything, except for UK government which has been fantastic on Carbon reductions, The Senator and acolytes would have trouble explaining the disappearing Arctic Ocean ice, not that someone is capable of «Hoaxing» vanishing multi year ice, and even further, failing to match their statements with Polar ice disappearing in tandem with world wide temperatures being flat, not rising for ten years now, as they like to claim, how to explain the disappearing ice then??? Those trying to explain a long term cycle, beware!

Paul S (# 1)-- Since the Planck Response dominates over positive feedback responses to temperature, wouldn't a La Nina - like failure of surface temperature to rise lead to an increase rather than a reduction in energy accumulation compared with accumulation during a surface warming — presumably a small increase, so that the observed rise in ocean heat content would still be substantial?

Gavin, I agree completely with the standard picture that you describe, but I don't agree with the claim that ``... as surface temperatures and the ocean heat content are rising together, it almost certainly rules out intrinsic variability of the climate system as a major cause for the recent warming».

it seems that your conclusion:» the observed relationship between increased intensity of TCs and rising ocean temperatures appears to be robust» is in direct contradiction with your conclusion «our knowledge of likely future changes in hurricanes or tropical cyclones (TCs) remains an uncertain area of science».

By contrast, there is quite a lot of data now telling us that CO2 is not a climate driver: We did the experiment of adding a large slug of CO2 to the air and the temperature stopped rising in 1997, the stratosphere stopped cooling in 1995 and the oceans showed no warming down to 700m when we replaced guesswork with accurate measurement in 2003.

Of course there is a meaning when it rises and when it falls, even if it only tells us that the oceans breath with the breath of temperature.

If the rather quick response of CO2 rise / year just 5 - 9 months after temperature changes reflects equilibrium with the oceans, then we are only in physical contact with the upper meters of the ocean.

This CO2 - driven acidification of the oceans is already under way in our own epoch of global warming - and that same oceanic response in the past coincides with massive rises in temperature - the hyperthermal.
