For example, one has to assume a change from, say, 25 to 26 degrees has the same relative effect on the proxy as a change from 30 to 31 degrees. (climate-skeptic.com)
As noted in this paper, the days of learning conversion is an approximate translation, meant to add context and aid in the understanding of relative effect size.73 Unlike the actual effect size, the days of learning conversion should not be interpreted as a precise measurement of learning for policy use.

The other obvious observation is that water vapor has more relative effect in the tropics, where it is moister. (realclimate.org)
