<DIV>Nick and William,</DIV>

<DIV>You’re right and more specific than I was. I generalized to 47
degrees but the difference is really minor. Actual location of the tropics
of Cancer and Capricorn is approximately 23.44 degrees and that location varies
by about a half second a year but it is minor in terms of this discussion.
This has been helpful because I’ve always simply referred to it as 23.5 degrees
N and S so knowing the specific location and the minor variation is interesting
information. But anyone’s specific latitude location on the planet is
really irrelevant to the difference between Solstices in terms of degrees of
tilt. It is the same everywhere.</DIV>

wider the summer to winter sun angle.â<BR> <BR>Bob-O. Explain
this one to me please. The difference between winter solstice and summer
solstice sun angle is 47 degrees, everywhere on the planet, even in
Hawaii. I suspect that in higher latitudes a lower sun angle means more
atmosphere to affect insolation but the planet, last time I checked, is tilted
the same
everywhere.<BR> <BR>Tom<BR> <BR> <BR> <BR>_______________________________________________<BR>List
