From the perspective of the planetary energy balance heat storage in the ocean is the key mechanism.

The general argument however is being discussed by rasmus in the context of planetary energy balance: the impact of additional CO2 is to reduce the outgoing longwave radiation term and force the system to accumulate excess energy; the imbalance is currently on the order of 1.45 * (10 ^ 22) Joules / year over the globe, and the temperature must rise allowing the outgoing radiation term to increase until it once again matches the absorbed incoming stellar flux.

But with the transparent window, Tt is now decoupled from being constrained to maintain the planetary energy balance requirement as set by Te.

in the pipeline from past / current high GHG emissions which science has already told us all is going to impact the planetary energy balance...]

This is because part of the outgoing radiation signal (albeit small) is emerging from relatively warm layers aloft, and thus slightly less emission is demanded from the troposphere in order to satisfy planetary energy balance.

Complete restoration of the planetary energy balance (and thus full adjustment of the surface temperature) does not occur instantaneously due to the inherent inertia of the system, which lies mainly in the slow response times of the oceans and cryosphere.

Very recent, wide ranging review of temperature measurements in the oceans with a detailed discussion of the accuracy of the data, planetary energy balance and the effect of the warming on sea levels.

Perhaps there is room for more indicators inspired by the «big picture physics», such as the planetary energy balance and the outgoing long - wave radiation (OLR).

The principal climate forcing, defined as an imposed change of planetary energy balance [1]--[2], is increasing carbon dioxide (CO2) from fossil fuel emissions, much of which will remain in the atmosphere for millennia [1], [3].

Our evaluation of a fossil fuel emissions limit is not based on climate models but rather on observational evidence of global climate change as a function of global temperature and on the fact that climate stabilization requires long - term planetary energy balance.

Yet we suggest that a pathway is still conceivable that could restore planetary energy balance on the century time scale.

A slower growth rate of the net climate forcing may have contributed to the standstill of global temperature in the past decade, but it can not explain the standstill, because it is known that the planet has been out of energy balance, more energy coming in from the sun than energy being radiated to space.10 The planetary energy imbalance is due largely to the increase of climate forcings in prior decades and the great thermal inertia of the ocean.

The identified atmospheric feedbacks including changes in planetary albedo, in water vapour distribution and in meridional latent heat transport are all poorly represented in zonal energy balance model as the one used in [7] whereas they appear to be of primary importance when focusing on ancient greenhouse climates.
