The total GHE experiences a 25 % swing every six months.
If nitrogen only is enough to cause an atmosphere to warm without any RHT, then convective heat transfer is part of
the total GHE and not a reduction in the GHE.
If a doubling of CO2 resulted in a temperature increase of approximately 1 K before any non-Planck feedbacks (before water vapor, etc.), then assuming the same climate sensitivity to
the total GHE, removing the whole GHE would result in about a (setting the TOA / tropopause distinction aside, as it is relatively small relative to the 155 W / m2 value) 155/3.7 * 1 K ~ = 42 K. Which is a bit more than 32 or 33 K, though I'm not surprised by the difference.
If you want to see how
the total GHE can be approximately calculated, see, for example, Kiehl and Trenberth 1997, from links here: http://chriscolose.wordpress.com/2008/12/10/an-update-to-kiehl-and-trenberth-1997/ — Kiehl and Trenberth 1997: http://www.atmo.arizona.edu/students/courselinks/spring04/atmo451b/pdf/RadiationBudget.pdf — see also the link for K
Not exact matches
For instance, the
GHE is based on increasing the residence time of certain WL of LWIR energy via redirecting exiting LWIR energy back into the system, while input remains constant, thus more
total energy is within the system.
That change corresponds to a
total change to the
GHE of 0.9 °C which I will consider 1 °C as the ozone transfer really takes place in the stratosphere.
We are more sure, given the
total data, of
GHE and its dominant influence on GMT when taken with aerosols than we are of the Higgs boson, by far.
CH4, O3, OH and others in the stratosphere and up, that ignored 20 % of the atmosphere, with Brewer - Dobson circulation, refraction / defraction that adds about 1.5 hours to the «day» as twilight and absorbs about 20Wm - 2 of the 75Wm - 2
total SW atmospheric absorption might be called
GHE 201.
You get the real
GHE from correct radiation physics, which is that thermal IR from the lower atmosphere blocks surface IR emission in GHG band centres, reducing
total emissivity.
Given that we are told that panel f represents
total forcings, I'm guessing that the others must be specific forcings; probably c is
GHE, and I speculate that maybe d is ozone.
