It is impossible to tell anything about the earth at all...
...unless it supports business interests. Then it is a priori, and you need no measurements at all.

- I still don't see why it's temperature dependent. (n/t)
- 'Heavy' water molecules will evaporate from the ocean at a different rate than light ones
- R.L. That makes sense; however, is that truely indicative of "global" tempatures or just "polar region" tempatures?
- A pretty good article at Wikipedia
- There are also small chemical differences in how differing isotopic water compositions react
- I knew that. I was just too dumb to think of it. (n/t)

- Thanks for the info.

- "Even now, for some reason, modern temperature changes and warming seem to be mostly confined to the northern hemisphere."
