Part 3 of our deep dive into Charles Hapgood's The Path of the Pole. This week, we look at more evidence of past pole configurations different from the present, as well as evidence against the idea that in the past, the earth spent long periods of time with a uniformly warm or cold climate, which was one of the attempts to explain away evidence for warm climate flora and fauna in what are now polar regions, and evidence for polar conditions in what are now tropical and sub tropical areas.
