Rather than use a model - based estimate, as did Hansen (2005) and Trenberth (2009), the authors achieve this by calculating it from observations of ocean heat content (down to 1800 metres) from the PMEL / JPL / JIMAR data sets over the period July 2005 to June 2010 - a time period dominated by the superior ARGO - based system.

To calculate the Earth's total heat content, the authors used data of ocean heat content from the upper 700 metres.

The models serve merely to quantify these basic facts more accurately, calculate the regional climate response, and compute effects (such as the expected increase in ocean heat content or sea level) which can be tested against observed data from the real world.

Which implies that since the late» 40's - early» 50's we have had a data collection system deployed capable of measuring and tracking the annual TEMPERATURE of the top 2000 meters of the oceans of the world (necessary to calculate its heat content)-- all of them — with a precision and accuracy in the millidegree range.

Because 5 gazillion Joules is a 0.2 C mixed layer (top ~ 300 meters) surface temperature rise (Figure 10, Historical ocean heat content calculated from HadSST and OHC, Levitus, 2009).

When the first analyses of Ocean Heat Content calculated from old temperature data from the oceans where first published in the early 2000's, they were described as the «Smoking Gun».

Essentially, Huber and Knutti take the estimated global heat content increase since 1850, calculate how much of the increase is due to various estimated radiative forcings, and partition the increase between increasing ocean heat content and outgoing longwave radiation.

«TCR and ECS are calculated by regressing ensemble - average decadal mean forcing or forcing minus ocean heat content change rate against ensemble - average temperature change.»

What are the error bars in calculating the heat content of an entire ocean from the sparse, unreliable (pre-ARGO) temperature data available?

Bosse (Citizen Scientist / Public), 4.1 (± 0.43), Statistical (Same as June) Just as in the two years before I calculate the value for the September - minimum of the arctic sea ice extent of the year n (NSIDC monthly mean for September) from the Ocean Heat Content (0... 700m depth) northward 65 ° N during JJAS of the year n - 1.

Because you are fitting to look for a trend * after * selecting the data that looks flat, the real 95 % confidence interval of the trend in temperature (or ocean heat content) over any of these intervals is much larger than what you are presumably calculating.

This is in part because there are several open research questions regarding the accuracy with which ocean heat content can be calculated and applied.

As I understand it global temperatures are calculated as anomalies, thus removing seasonal swings, but that Heat Content is not, Now our dear planet has an elliptical orbit and is sometimes closer to the sun that others; sure, the shape of the land and oceans doesn't mean that the amount of incoming solar radiation falling on the oceans follows the Earths orbit, but it should be possible to work out the amount of incoming solar radiation each quarter.

A recently published estimate of Earth's global warming trend is 0.63 ± 0.28 W / m2, as calculated from ocean heat content anomaly data spanning 1993 - 2008.
