I wonder if Astor knew that the obliquity of the earth changes
naturally. That would have been a fairly recent discovery, though it
would be another decade or more until Ludwig Pilgrim solved the problem
of exactly how it changed over time.
I don't think a zero obliquity world would have quite the positive
effect on the US that Mr Astor's characters are expecting. At a guess,
a narrow strip around 30 latitude would profit, everywhere else things
would be worse.
At a very rough estimate about fifteen million square kilometers of
shelf are exposed for a sea level drop of 120m. However, several
million of these are in the Arctic. Given also that the Laurentide ice
sheet alone was 13 million km in extent and the Fennoscandian a further
seven, plus Siberian ice, (a small amount of this was over what is now
water) and I think it's clear we didn't have more land to live on in the
last ice age.
But it would double the size of Florida. If that means we get two
Carl Hiassens, that's a plus.
With our luck, we'll get two Piers Anthonys.

Or two DeSantis, forfend!

I wouldn't know about that, but the project he proposed in jest in his
book was proposed in earnest on USENET by the late mathematician
Alexander Abian for a while.
