The relative importance of climate and hunting for the mammoth's fate has long been debated but rarely assessed quantitatively.

WASHINGTON (AP) -- The rains stopped coming, the temperature rose and the great grasslands of North Africa turned to desert a few thousand years ago -- changes that may have helped spur development of civilization in the Nile Valley.

These deposits have changed our thinking about the total volume of erupted material from the Minoan eruption, said URI volcanologist Haraldur Sigurdsson.

Irish Tree Rings and an Event in 1628 BC In prehistoric times, oaks growing on the surface of Irish raised bogs were recording rare extreme events.

So concludes a group of anthropologists in a new assessment of the demise of the coastal Peruvian people who built the earliest, largest structures in North or South America before disappearing in the space of a few generations more than "This maritime farming community had been successful for over 2,000 years, they had no incentive to change, and then all of a sudden, 'boom,'" said Mike Moseley, a distinguished professor of anthropology at the University of Florida.

"They just got the props knocked out from under them." was driven by the disappearance of its icy habitat combined with the emergence of human hunters, scientists have confirmed.

This eruption also affected the Mayans, the events in the exodus part of the bible and probably destroyed the Indus civilisation which ended around 1500bc [edit on 28-1-2010 by loner007] You're talking about a discrepancy of 50-100 years from an event that occurred approximately 3,600 years ago. Gerry Neugebauer, IRAS chief scientist for California's Jet Propulsion Laboratory and director of the Palomar Observatory for the California Institute of Technology said in an interview.

I think carbon dating and especially tree ring analysis is more accurate than unspecified "archeological evidence." When you add the sudden demise of a successful 2,000 year-old Peruvian civilization, the sudden extinction of the Wooly Mammoth, ice core samples that suggest "great geologic stress" and the Sahara grasslands suddenly turning to desert that was "triggered by changes in the Earth's orbit and the tilt of Earth's axis" -- all of which happened 3,600 years ago -- it doesn't take a genius to conclude that there's most likely something to Mayan prophecies. The most fascinating explanation of this mystery body, which is so cold it casts no light and has never been seen by optical telescopes on Earth or in space, is that it is a giant gaseous planet, as large as Jupiter and as close to Earth as 50 billion miles.

The time scale for each ionic component level as well as the O (sup 18) levels stretches back 30,000 years. The 1628 BC event that really slammed the tree rings shows almost no registration in the antarctic cores in terms of volcanic activity.The exact date of the eruption, however, is unknown. So mysterious is the object that astronomers do not know if it is a planet, a giant comet, a nearby "protostar" that never got hot enough to become a star, a distant galaxy so young that it is still in the process of forming its first stars or a galaxy so shrouded in dust that none of the light cast by its stars ever gets through.Radiocarbon dating indicates that the eruption occurred about 1645—1600 BC.[3] These dates, however, conflict with the usual date range from archaeological evidence, which is between about 15 BC.[4] For more discussion, see the article on the Minoan eruption. government has known this since 1983: The Washington Post, Page A1 December 31, 1983 A heavenly body possibly as large as the giant planet Jupiter and possibly so close to Earth that it would be part of this solar system has been found in the direction of the constellation Orion by an orbiting telescope aboard the U. "All I can tell you is that we don't know what it is," Dr.None of the evidence you provided gives an indication for such an occurrance? Maybe they just had to displace from where they were - given their land was no longer hospitable.

As for wiping out of a culture 2000 years strong, are there not peruvians to this day? the exact date is unknown as spedcified in the post.

One of these events occurs in the decade of the 1620s BC and coincides very precisely with a previously suggested volcanic event at 1626 BC (now 1627 BC) put forward by La Marche.
