It really is straight forward, well understood physics....

Isotopic mass differences lead to a fractionalizing of various processes- such as evaporation- this will have a strong temperature dependence, and will be reflected in ice core data. The science is very strong.

        R.L. That makes sense; however, is that truely indicative of "global" tempatures or just "polar region" tempatures? - Scott Evil - 2/9/2007 2:38:04 PM

        There are also small chemical differences in how differing isotopic water compositions react - R.L. - 2/9/2007 12:52:28 AM

        The answer is probably not a simple one, and related to many factors. (n/t) - TB - 2/8/2007 9:06:07 PM
        
        The dates of perihelion and aphelion might be a factor, too. - LS - 2/8/2007 9:53:40 PM
