The iris hypothesis and the tropical
upper tropospheric water vapor and cirrus cloud feedbacks, while arguably still open to debate, are not
by any stretch of the imagination a major driver in global climate feedback.
«The wavelengths of
water vapor continuum absorption are most important in determining surface emission, while
upper tropospheric emission is determined
by the wavelengths of rotation and vibrational bands (Mitchell et al. 1987; Inamdar et al. 2004).»
(This paper,
by Shine & Sinha, appears to have been inspired
by Lindzen's 1990 paper where he talked about the importance of
upper tropospheric water vapor among other subjects).
The high level of interest in scientific circles in
upper tropospheric (and stratospheric)
water vapor is because it is easy to demonstrate
by theory and measurement that small amounts of
water vapor at high altitudes have disproportionate effects.
