Thanks. I've grown to realize that since I posted.
Elifritz is right in the sense that I'm rather unfamiliar with the set of
problems that has focus in the climate debate. It doesn't prevent me
participating though. One question has come up while reading: The low
frequency window that is somewhat central in the wavefrequences where Earth
surface has maximum irradiance seems to be the only radiation conduite
through which Earth irradiates energy - or the only one that seems to be
calculated on. I havn't had much success in finding sources on irradiation
in the transparant parts of the spectrum - and possible mechanisms of
transfer of energi from the opaque to the transparent irradiation.
I'll take a look at the links that Graham P. Davis sent.
