When you change the conditions of
radiative energy coming in, the temperature of the CO2 will need to adjust in order to radiate it away.

There are multiple non-
radiative energy fluxes at the surface (latent and sensible heat fluxes predominantly) which obviously affect the atmospheric temperature profiles, but when it
comes to outer paces, that flux is purely
radiative.
The point isn't a «perpetual increase in atmospheric pressure» — that's a misnomer — if you consider the MASS of the atmosphere that is continuously «pumped» from cold air to hot air to cold air again, high up in the atmosphere — that creates «potential
energy» from the kinetic
energy of the convection — adiabatic expansion of the atmosphere is the result — the adiabatic compression occurs on the return trip of the previously warmed (from
radiative energy) air as it completes the «cycle» as it
comes back down!
The
energy balance at the glacier surface shows that the greatest
energy available to melt ice
comes from the
radiative balance.
The fundamental hypothesis is that at some time in the past and over some unspecified time - averaging period that on a whole - planet basis
radiative energy transport attained a state of equilibrium; out - going
energy = in -
coming energy.
The accumulated
energy has to
come from something affecting the
radiative balance of the planet, not just distributional factors.
Radiative forcing is a measure of the change in boundary conditions, to which the climate system responds by either warming (in the case of positive radiative forcing; more energy coming in than going out) or cooling (negative radiative

So, that is what we
came up with — A few very simple models, such as the one that involves 3 objects: one object A producing thermal
energy and radiating
energy at a fixed rate, two other objects B and C whose temperature is determined via
radiative balance with object A and empty space, with a geometry such that the temperature of object B is higher than that of object C. And, what we wanted to illustrate is that the object C «warms» B in the colloquial sense of the word... i.e., that the presence of object C causes B to be at a higher temperature than if C is absent.
Physical science is highly constrained by what is known about
energy budgets, paleoclimate and
radiative transfer in gases, and alternate hypotheses are hard to
come by as the skeptics well know by now after a decade of trying.
How can it be called no - feedback when the base temperature used in the calculation is for a planet that is surrounded by material that reflects part of the in -
coming SW
radiative energy and in the case of Earth that material is phases of water?
