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 The current interglacial period (circa 2000 AD) is apparently no more stable than any before it. The last major interglacial was between 128,000 BC and 114,000 BC. Ice Ages apparently may begin or end quickly. The current heating of the world by mankind however is a new wild card in the mix. If the planet's natural Ice Age cycle isn't much affected by human works, and the present interglacial continues for another 10,000 years, the Earth could get very hot indeed. On the other hand, if mankind can hurry the next Ice Age along, or its natural schedule is simply faster than we expect, then our extra heat production might help postpone the glaciers while keeping planetary temperatures about the same as they were over the past thousand years. -- Essay: Climate Future Told Through Mud ["http://www.discovery.com/news/briefs/20000214/weather_interglacial.html"] By Larry O'Hanlon, Discovery.com News, February 14, 2000 |
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.
East China, circa 124,000 BC
Around 124,000 BC human beings are apparently living in an area which millennia from now will be known as Zhejiang Province in east China. These people are using a variety of stoneware, including tools for smashing and cutting, hatchets, and stone balls.
