>If you had studied Thermodynamics, you would know that the ONLY thing that will trap the Heat from the Sun is a change in the R of air, i.e. it's heat retaining properties.
The effect that is usually discussed is the so-called greenhouse effect. As I understand it, this is not directly related to the principles of thermodynamics, and especially to the properties you mention.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
