Pre-Modern Astronomy vs Habitable Venus

[Cray]

Interesting article. Has there been follow-up research verifying the idea?

Slow rotation, in
turn, reduces the temperature contrast between the
poles and equator which may play a role in making
the Earth’s Ice-Ages rare and relatively mild

Eenteresting. So if rotation speeds up a bit, perhaps to 18-20 hours, that might make the poles more habitable.

On the other hand, apparently slow rotating planets can get closer to stars and handle heat fluxes higher than Venus's: http://beyondearthlyskies.blogspot.com/2...on-on.html

Gee, 256-day rotation keeps a cloudy Venus positively frosty according to that paper.
