Of course, it also
reduces radiative heat losses too.
It would provide important insight into how much SRM would
reduce radiative heating, the concentration of water vapor in the stratosphere, and the processes that determine water vapor transport — which affects the concentration of ozone.

However, the colder ocean surface
reduces upward
radiative, sensible and latent
heat fluxes, thus causing a large (∼ 50 W m − 2) increase in energy into the North Atlantic and a substantial but smaller flux into the Southern Ocean (Fig. 8c).
It is the
reduced amount of radiation leaving the top of the atmosphere that changes the earth's balance of
heat, and therefore defines the «direct
radiative forcing» caused by doubling CO2.
This makes sense given that the more rapid initial response for finite flow through the depth of the ocean
reduces the
radiative disequilibrium (the
heat source) faster, so that it then takes longer to
heat up the rest of the system (the weighted - average T of the system nearly follows the exponential decay for that amount of
heat capacity for ~ 2 years and then lags behind).
... interestingly in the grey gas case with no solar
heating of the stratosphere, increasing the optical thickness of the atmosphere would result in an initial cooling of and in the vicinity of the skin layer (
reduced OLR), and an initial
radiative warming of the air just above the surface (increased backradiation)-- of course, the first of those dissappears at full equilibrium.
Seriously — if this
heat pile up and CO2
radiative trapping of
heat really worked AND it is essential to
reduce greenhouse gas emissions then Engineers — who are actually smart unlike climate scientists — would have easily built a «Greenhouse gas coal fired power station.
Secondly, objects radiate proportion to the fourth power of surface temp, thus spreading the
heat over a larger surface
reduces radiative efficiency.
Radiative forcing only accounts for about 1/3 of ocean heat loss — when radiative heat loss is reduced the ocean simply loses more heat the way it loses the majority of its heat
Radiative forcing only accounts for about 1/3 of ocean
heat loss — when
radiative heat loss is reduced the ocean simply loses more heat the way it loses the majority of its heat
radiative heat loss is
reduced the ocean simply loses more
heat the way it loses the majority of its
heat already.
Replacing the vaccuum with CO2 would no doubt
reduce the conductive and convective insulation (ie increase conductive & convective
heat loss) theoretically
radiative heat loss should remain the same.
Convection can therefore compensate for
reduced radiative transfer if its mean vertical extent reaches the height of the planetary
heat loss.
In other words, the
reduced radiative energy flux must be compensated through increased temperatures or altered latent / sensible
heat fluxes.
-LCB- 9.4, Box 9.2 -RCB- • The observed reduction in surface warming trend over the period 1998 to 2012 as compared to the period 1951 to 2012, is due in roughly equal measure to a
reduced trend in
radiative forcing and a cooling contribution from natural internal variability, which includes a possible redistribution of
heat within the ocean (medium confidence).
