Re: Earth's Axial Tilt (posted for T. Hansen)

[Adam Woods <awoods@xxxxxxxxxxxxx>]

As far as I know, the earth's tilt has not changed beyond normal 
Milkankovitch shifts.  The rotation rate, however, has slowed down over 
time which has caused Milankovitch frequencies to become longer.  If you 
are interested, check out a 1992 paper by Berger, Loutre and Laskar 
(Science, v. 255. p. 560-565).

Hope this is helpful!
