Given those assumptions, looking at the forcing over a long - enough multi-decadal period and seeing the temperature response gives an estimate of the transient climate response (TCR) and, additionally if an estimate of the ocean heat content change is incorporated (which is a measure of the unrealised radiative imbalance), the ECS can be estimated too.

The key points of the paper are that: i) model simulations with 20th century forcings are able to match the surface air temperature record, ii) they also match the measured changes of ocean heat content over the last decade, iii) the implied planetary imbalance (the amount of excess energy the Earth is currently absorbing) which is roughly equal to the ocean heat uptake, is significant and growing, and iv) this implies both that there is significant heating «in the pipeline», and that there is an important lag in the climate's full response to changes in the forcing.

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.

use of ocean heat uptake — which amounts to only ~ 86 % of total heat uptake — as a measure of total heat uptake despite the observational studies Marvel et al. critique using estimates that included non-ocean heat uptake;

Just a guess, with out actually crunching the numbers, but the energy transfer (0.3 watt / m2) and the time frame (2003 — present) are both too small, to measure any transfer, in such a large heat sink as the oceans.

Instead, they discuss new ways of playing around with the aerosol judge factor needed to explain why 20th - century warming is about half of the warming expected for increased in GHGs; and then expand their list of fudge factors to include smaller volcanos, stratospheric water vapor (published with no estimate of uncertainty for the predicted change in Ts), transfer of heat to the deeper ocean (where changes in heat content are hard to accurately measure), etc..

While such a «missing heat» explanation for a lack of recent warming [i.e., Trenberth's argument that just can not find it yet] is theoretically possible, I find it rather unsatisfying basing an unwavering belief in eventual catastrophic global warming on a deep - ocean mechanism so weak we can't even measure it [i.e., the coldest deep ocean waters are actually warmer than they should be by thousandths of a degree]...

The «warming» of the troposphere as measured by sensible heat is only one very small part of the energy in the overall climate system, and the part with the very lowest thermal inertia and very sensitive to very small changes in ocean to atmosphere sensible and latent heat flux such as we see in the ENSO cycle.

The combined heat can be modeled at the surface but can not currently be measured because it has dived into some deep, lonely part of the ocean where it can't be found.
