mehus@19 dana1981@20 John Hartz@21 I inferred from Kevin Trenberth lecture on Utube that «missing heat» was discrepancy
between radiation imbalance (KT stated 0.9 wm ** -2) & delta ocean heat expected from it.

The researchers [3] quantified China's current contribution to global «radiative forcing» (the
imbalance, of human origin, of our planet's
radiation budget), by differentiating
between the contributions of long - life greenhouse gases, the ozone and its precursors, as well as aerosols.
This so - called constant - composition commitment results as temperatures gradually equilibrate with the current atmospheric
radiation imbalance, and has been estimated at
between 0.3 °C and 0.9 °C warming over the next century.»
An apparent inconsistency has been diagnosed
between interannual variations in the net
radiation imbalance inferred from satellite measurements and upper - ocean heating rate from in situ measurements, and this inconsistency has been interpreted as «missing energy» in the system2.
'' Global climate change results from a small yet persistent
imbalance between the amount of sunlight absorbed by Earth and the thermal
radiation emitted back to space1.
The
imbalance is not
between IR absorbed and IR emitted by a layer of atmosphere, but
between the incoming shortwave solar energy from space and the outgoing longwave energy emitted to space, due to the increasing difference
between the ground temperature and the temperature of the level from which re-emitted
radiation can escape to space.
Surface temperature is an imperfect gauge of whether the earth has been warmed by an
imbalance between incoming
radiation from the sun, and outgoing
radiation, because of the role of ocean currents in the distribution of heat
between deeper and surface waters.
The point made in the skeptical science article is that there is good quantitative agreement
between ocean heating and satellite measurements of the
radiation imbalance which is what one would expect to see.
The
imbalance between the absorbed and emitted
radiation that results from these changes will be referred to here as «climate forcing» (sometimes known as «radiative forcing») and given in units of Wm - 2.
From experimental evidence we know that the absorptivity of a body is not affected by the amount of incident
radiation, or by any
imbalance between the body and its environment.
However, from experimental evidence we know that emissivity of a body is not affected by the incident
radiation, or by any conditions of
imbalance that occur
between the body and its environment.
To determine how fast Earth's systems are accumulating heat, scientists focus on Earth's energy
imbalance (EEI): the difference
between incoming solar
radiation and outgoing longwave (thermal)
radiation.
If something occurs to cause an
imbalance between incoming and outgoing
radiation, then you can't, as a matter of principle, say that the system will change to maintain radiative balance, it depends on the system.
Douglas and Knox show some correlations
between Top - of - atmosphere
radiation imbalance and the Pacific Decadal Oscillation (PDO).
The IPCC model suggests that the heat and latent energy exchange
between the underlying surface and the atmosphere is a direct response to the
imbalance of solar energy and terrestrial
radiation at the surface.
Thus, long - term variations of TSI (with account for their direct and secondary, based on feedback effects, influence) are the main fundamental cause of climate changes since variations of the Earth climate is mainly determined by a long - term
imbalance between the energy of solar
radiation entering the upper layers of the Earth's atmosphere and the total energy emitted from the Earth back to space.»
A greenhouse forcing is caused by changing the OLR so there is an
imbalance between incoming shortwave
radiation and OLR.
