I'll post a comment when I have read it.

Quoting Alan Siddons:

Quote:Utterly false. Heated masses always emit light (infrared). Always. That's a direct consequence of molecules in motion. And while it's true that some substances may be transparent to infrared light, it doesn't follow that they can't be heated or, if heated, might not emit infrared. Yet NASA's misleading formulation implies precisely that.

There are three ways for heat (better to say thermal energy) to move from one zone to another: by conduction, convection, and radiation. Conductive heat transfer involves direct contact, wherein vibrations spread from molecule to molecule. Convective transfer involves a mass in motion: expanded by heat, a fluid is pushed up and away by the denser fluid that surrounds it. Radiative transfer arises when molecules intercept the light that warmer molecules are emitting, which brings about a resonant molecular vibration -- i.e., heating.

Heat is transferred and absorbed in several ways, then, and no substance is immune to being heated, which means that all gases absorb heat -- contrary to what NASA tells children.

Yeah NASA and AGW lovers forget that CONDUCTION exist.
