A rediscovery of the Milankovich Cycles.
Yeah, I thought this had been brought up before except she seems to be saying that a more eccentric orbit produces a minimal change in climate. and vice versa.
Thanks I could not remember his name. I read a small book regarding his theory about 20 years ago. I loaned it out and never got it back.
By the way: did she even mention Milankovich’s theory?
