I understand the superficial attractiveness behind the proposition that the
atmoshpere contains some gases that are largely transparent to incoming solar radiation and therefore the majority of this solar radiation finds its way through the atmosphere to the surface whereupon it heats the surface and this heat is, inter alia, radiated from the surface at a different wavelength at which wavelength the atmosphere (or some gases within the atmosphere) is not transparent such that some of this radiated enerrgy is «trapped» thereby effectively
warming the planet.
