28 Estimated Strength of Water Vapor Feedback Earliest studies
suggest that if the absolute humidity increases in proportion to the saturation vapor
pressure (
constant relative humidity), this will give rise to a water vapor feedback that will double the sensitivity of climate compared to an assumption of fixed absolute humidity.
Here, high
pressure studies show that force
constants of iron bonds increase with
pressure similarly for silicate and metals
suggesting interplanetary isotopic variability is not due to core formation.
