Thus, North America may be suffering terrific storms during the period between 116,000 BC and 108,000 BC. Note that in many cases (especially towards the end of this period, and/or in the more northern regions), these storms are horrific blizzards, laying down snow to form the advancing glaciers of the new Ice Age.

The last major break between Ice Ages was somewhere around 128,000 BC- 114,000 BC, lasting for roughly 14,000-20,000 years, depending on how you define the conditions (up to twice as long as the current period circa 2000 AD so far). Ice Ages can also begin and end pretty abruptly, and with perhaps little warning. -- Essay: Climate Future Told Through Mud ["http://www.discovery.com/news/briefs/20000214/weather_interglacial.html"] By Larry O'Hanlon, Discovery.com News, February 15, 2000 |
So far as is known circa March 2000, there are no human predecessors living in northern North America at this time.
Note that global sea levels now are likely near the same as circa 1999 AD (or slightly higher), thereby insuring that land links such as the Bering landbridge (and many islands) are submerged. The greater southeast asian peninsula is also in large part underwater, presenting something a bit smaller than its circa 1999 AD incarnation to surface observation.
