However, radiation changes at the top of the atmosphere from the 1980s to 1990s, possibly related in part to the El Niño - Southern Oscillation (ENSO) phenomenon, appear to be associated with reductions in tropical upper - level cloud cover, and are linked to changes in the energy budget at the surface and changes in observed ocean heat content.

Figure 3 is the comparison of the upper level (top 700m) ocean heat content (OHC) changes in the models compared to the latest data from NODC and PMEL (Lyman et al (2010), doi).

Changes in Hadley circulation affects convection and thus atmospheric moisture content and cloud cover which may in turn affect net solar heating as well as the transfer of heat from Earth to space.

Contributions to the event arising from changes in ocean heat content were shown to be negligible.

Another figure worth updating is the comparison of the ocean heat content (OHC) changes in the models compared to the latest data from NODC.

Positive energy content change means an increase in stored energy (i.e., heat content in oceans, latent heat from reduced ice or sea ice volumes, heat content in the continents excluding latent heat from permafrost changes, and latent and sensible heat and potential and kinetic energy in the atmosphere).

We assess the heat content change from both of the long time series (0 to 700 m layer and the 1961 to 2003 period) to be 8.11 ± 0.74 × 1022 J, corresponding to an average warming of 0.1 °C or 0.14 ± 0.04 W m — 2, and conclude that the available heat content estimates from 1961 to 2003 show a significant increasing trend in ocean heat content.

You've got the radiative physics, the measurements of ocean temperature and land temperature, the changes in ocean heat content (Hint — upwards, whereas if if was just a matter of circulation moving heat around you might expect something more simple) and of course observed predictions such as stratospheric cooling which you don't get when warming occurs from oceanic circulation.

This means that, e.g., if heat moves from the tropical surface water (temp about 25C) to surface waters at lower temps, the net effect is a subsidence of sea level — even without any change in total heat content.

The next figure is the comparison of the ocean heat content (OHC) changes in the models compared to the latest data from NODC.

In this work the equilibrium climate sensitivity (ECS) is estimated based on observed near - surface temperature change from the instrumental record, changes in ocean heat content and detailed RF time serieIn this work the equilibrium climate sensitivity (ECS) is estimated based on observed near - surface temperature change from the instrumental record, changes in ocean heat content and detailed RF time seriein ocean heat content and detailed RF time series.

We assess the heat content change from both of the long time series (0 to 700 m layer and the 1961 to 2003 period) to be 8.11 ± 0.74 × 1022 J, corresponding to an average warming of 0.1 °C or 0.14 ± 0.04 W m — 2, and conclude that the available heat content estimates from 1961 to 2003 show a significant increasing trend in ocean heat content.

Since the IPCC's graph above up to 2003 shows that most of the energy from global warming is in the oceans, to a first approximation, Ocean Heat Content change since then is going to be close enough to the Total Heat Content change.

With a dominant internal component having the structure of the observed warming, and with radiative restoring strong enough to keep the forced component small, how can one keep the very strong radiative restoring from producing heat loss from the oceans totally inconsistent with any measures of changes in oceanic heat content?

''... how can one keep the very strong radiative restoring from producing heat loss from the oceans totally inconsistent with any measures of changes in oceanic heat content?»

Not all at once of course, but as mentioned above, when the PDO goes positive, we can likely expect a significant change in the atmospheric heat content as heat energy is transferred from the deep oceans back into the atmosphere.

The rate of warming as measured by ocean heat content changes over the last 4 years shows that we have DOUBLED the top - of - atmosphere energy imbalance from 0.6 watts per meter squared to 1.1 watts per meter squared in the last 7 years.

Actually Fielding's use of that graph is quite informative of how denialist arguments are framed — the selected bit of a selected graph (and don't mention the fastest warming region on the planet being left out of that data set), or the complete passing over of short term variability vs longer term trends, or the other measures and indicators of climate change from ocean heat content and sea levels to changes in ice sheets and minimum sea ice levels, or the passing over of issues like lag time between emissions and effects on temperatures... etc..

They are mainly derived from the Shaviv reference (provided in the link above) that concludes that the solar signal is amplified as indicated by the magnitude of changes in ocean heat content (and other less direct measures) over the course of the 11 year solar cycle.

It takes a lot of heat energy to increase the heat content of the oceans to a measuable extent and brings up the question of whether this increased heat content is coming from the sun or from changes in the rate of geothermal heat transfer from within the Earth itself.

The TOA energy imbalance can probably be most accurately determined from climate models and is estimated to be 0.85 ± 0.15 W m - 2 by Hansen et al. (2005) and is supported by estimated recent changes in ocean heat content (Willis et al. 2004; Hansen et al. 2005).

The natural internal variability of the climate system arises from factors such as El Niño, fluctuations in the thermohaline circulation, and changes in ocean heat content.

All that is needed is to add heat carried upwards past the denser atmosphere (and most CO2) by convection and the latent heat from water changing state (the majority of heat transport to the tropopause), the albedo effects of clouds, the inability of long wave «downwelling» (the blue balls) to warm water that makes up 2 / 3rds of the Earth's surface, and that due to huge differences in enthalpy dry air takes far less energy to warm than humid air so temperature is not a measure of atmospheric heat content.

Simply changing the carbon dioxide content of the atmosphere by 30 percent has major impacts in the adiabatic lapse rate and the rate at which radiated heat is passed from the planet.

Apparently, these GCMs can «forecast» climate change only «a posteriori», that is, for example, if we want to know what may happen with these GCMs from 2012 to 2020 we need first to wait the 2020 and then adjust the GCM model with ad - hoc physical explanations including even an appeal to an unpredictable «red - noise» fluctuation of the ocean heat content and flux system (occurring in the model in 2055 and 2075!)

This is a blow - up of the changes in the heat content of the top 300 meters and then from 300 to 700 meters.
