: : James,
: : Is the greenhouse effect equivalent to the atmosphere, or are they different things?
: The greenhouse effect is caused by the presence
: of the atmosphere. If there were no atmosphere,
: there would be no greenhouse effect. The only
: way to have an atmosphere and no greehouse effect
: is if the atmosphere contained only gases that
: were completely transparent (no absorbing) to
: longwave radiation in the emission region of the
: planet. So, they are not formally equivalent,
: but the presence of an atmosphere usually implies
: that the planet will have at least some greenhouse
: effect.
