(nor) to repeat the caveat that no individual weather event can be directly linked to climate change.»
We start out by placing a warm object — say a heated piece of iron — in the chamber, and then sealing the chamber, Our principle tells us that the heat from the iron will cause the air to cool by emitting even more heat than it receives.
Re 392 Chris Dudley — I don't understand what you mean by R ^ 2T ^ 4 — and there should be something about how optical depth is proportional to R, and also, if you're going a significant distance toward the center of such an object, there is the issue of spherical geometry; if the optical thickness is large enough across small changes in radius, then you don't need to account for the spherical geometry in the calculation of the flux per unit area as a function of the temperature profile and optical thickness; however, the flux per unit area outward will drop as an inverse square, except of course within the layers that are being heated through a different process (SW heating for a planet, radioactivity, latent and sensible heat loss associated with a cooling interior, gravitational potential energy conversion to enthalpy via compression (adiabatic warming) and settling of denser material under gravity (the later both leads to compression via increased pressure via increased gravity within the interior, and also is a source of kinetic energy which can be converted to heat)...

While you might not realise it, all warm objects are constantly cooling down by emitting light, including us.
ie, earth has warmed, co2 a ghg, man contributes co2, warming caused in part due to man vs natural processes, for varying opinions of how big that part is) the activist have tried to label them otherwise, not believing earth has warmed (being ambiguous on cause), or not believeing co2 a ghg by never defining, the object of the consensus..
(c) It may also be objected that the atmospheric circulation depends on the difference of temperature between low and high latitudes and, hence, should be weakened instead of strengthened by a warming in the arctic.
