    Traces of platinum, a metal associated with meteorite impact, have been found at archaeological sites of the Clovis people across the US, suggesting that they were wiped out in a mini-Ice-Age triggered by the impact of an extraterrestrial object. The Clovis people disappeared from North America about 12,800 years ago. Many of the large creatures they hunted – a total of about 35 species – went extinct at about the same time.

    Rock soil droplets formed by heating most likely came from Stone Age house fires and not from a disastrous cosmic impact 12,900 years ago, according to new research from the University of California, Davis. The study, of soil from Syria, is the latest to discredit the controversial theory that a cosmic impact triggered the Younger Dryas cold period. The Younger Dryas lasted a thousand years and coincided with the extinction of mammoths and other great beasts and the disappearance of the Paleo-Indian Clovis people. In the 1980s, some researchers put forward the idea that the cool period, which fell between...

    THE last ice age 13,000 years ago took hold in just one year, more than ten times quicker than previously believed, scientists have warned. Rather than a gradual cooling over a decade, the ice age plunged Europe into the deep freeze, German Research Centre for Geosciences at Potsdam said. Cold, stormy conditions caused by an abrupt shift in atmospheric circulation froze the continent almost instantly during the Younger Dryas less than 13,000 years ago – a very recent period on a geological scale. The new findings will add to fears of a serious risk of this happening again in the...

    Canadian geologists say they can shed light on how a vast lake, trapped under the ice sheet that once smothered much of North America, drained into the sea, an event that cooled Earth's climate for hundreds of years. During the last ice age, the Laurentide Ice Sheet once covered most of Canada and parts of the northern United States with a frozen crust that in some places was three kilometres (two miles) thick. As the temperature gradually rose some 10,000 years ago, the ice receded, gouging out the hollows that would be called the Great Lakes. Beneath the ice's thinning...
  • Earth could plunge into sudden ice age

    In the film, "The Day After Tomorrow," the world gets gripped in ice within the span of just a few weeks. Now research now suggests an eerily similar event might indeed have occurred in the past. Looking ahead to the future, there is no reason why such a freeze shouldn't happen again — and in ironic fashion it could be precipitated if ongoing changes in climate force the Greenland ice sheet to suddenly melt, scientists say. Starting roughly 12,800 years ago, the Northern Hemisphere was gripped by a chill that lasted some 1,300 years. Known by scientists as the Younger...

    Science Codex ^ | 5-13-2014
    Controversy over what sparked the Younger Dryas, a brief return to near glacial conditions at the end of the Ice Age, includes a theory that it was caused by a comet hitting the Earth. As proof, proponents point to sediments containing deposits they believe could result only from a cosmic impact. Now a new study disproves that theory, said archaeologist David Meltzer, Southern Methodist University, Dallas. Meltzer is lead author on the study and an expert in the Clovis culture, the peoples who lived in North America at the end of the Ice Age. Meltzer's research team found that nearly...

    A meteor or comet impact near Quebec heaved a rain of hot melted rock along North America's Atlantic Coast about 12,900 years ago, a new study claims. Scientists have traced the geochemical signature of the BB-sized spherules that rained down back to their source, the 1.5-billion-year-old Quebecia terrane in northeastern Canada near the Gulf of Saint Lawrence. At the time of the impact, the region was covered by a continental ice sheet, like Antarctica and Greenland are today. Around this time, a global cooling began and the big animals in North America all vanished. Their human hunters, the Clovis people,...

    Early Americans faced rapid late Pleistocene climate change and chaotic environments The environment encountered when the first people emigrated into the New World was variable and ever-changing, according to a Penn State geologist. "The New World was not a nice quiet place when humans came," says Dr. Russell Graham, associate professor of geology and director of the Earth & Mineral Sciences Museum. Archaeologists agree that by 11,000 years ago, people were spread across North and South America, but evidence is building for an earlier entry into the New World, a date that would put human population of North and South...

    Mesopotamian climate change Geoscientists are increasingly exploring an interesting trend: Climate change has been affecting human society for thousands of years. At the American Geophysical Union annual meeting in December, one archaeologist presented research that suggests that climate change affected the way cultures developed and collapsed in the cradle of civilization — ancient Mesopotamia — more than 8,000 years ago. Archaeologists have found evidence for a mass migration from the more temperate northern Mesopotamia to the arid southern region around 6400 B.C. For the previous 1,000 years, people had been cultivating the arable land in northern Mesopotamia, using natural rainwater...

    As sabre tooth tigers and woolly mammoths were wandering around Europe, unique, giant prehistoric animals were living in Australia -- three metre tall kangaroos and wombat-like creatures, the size of a four-wheel drive, were just some of the curious creatures Down Under. Yet mysteriously, sometime during the last 100,000 years, they disappeared forever. The extinction of these giant animals, known as megafauna, has generated great debate. One group advocates "human blitzkrieg" -- those asserting the first Australians hunted these beasts to extinction. Others, myself included, find there is too little evidence to confidently attribute responsibility to any particular factor. Nonetheless,...

Since our own Galactic core presently appears quiescent, they believed it would likely remain inactive for many tens of millions of years. Although, in 1977, astronomer Jan Oort cited evidence that our Galactic core has been active within the past 10,000 years. Prediction No. 1...

    Terrestrial Evidence of a Nuclear Catastrophe in Paleoindian Times by Richard B. Firestone & William Topping The Paleoindian occupation of North America, theoretically the point of entry of the first people to the Americas, is traditionally assumed to have occurred within a short time span beginning at about 12,000 yr B.P. This is inconsistent with much older South American dates of around 32,000 yr B.P.1 and the similarity of the Paleoindian toolkit to Mousterian traditions that disappeared about 30,000 years ago.2. A pattern of unusually young radiocarbon dates in the Northeast has been noted by Bonnichsen and Will.3,4 Our research...

    Professor Stanley H. Ambrose Department of Anthropology, University Of Illinois, Urbana, USA Extract from "Journey of Human Evolution" [1998] 34, 623-651 The last glacial period was preceded by 1000 years of the coldest temperatures of the Late Pleistocene, apparently caused by the eruption of the Mount Toba volcano. The six year long volcanic winter and 1000-year-long instant Ice Age that followed Mount Toba's eruption may have decimated Modern Man's entire population. Genetic evidence suggests that Human population size fell to about 10,000 adults between 50 and 100 thousand years ago. The survivors from this global catastrophy would have found refuge...

The Clovis people, who roamed large portions of North America 10,800 to 11,500 years ago and left behind highly distinctive and deadly fluted spear points, have been implicated in the exterminations by some scientists. Now researchers from the University of Washington and Southern Methodist University who examined evidence from all suggested Clovis-age killing sites...

This ``Maunder Minimum'' is not only of interest to solar physicists in the context of the theory of solar magnetic activity, and to stellar astrophysicists working on the properties of cool stars, but may also be a vital clue to the influence of the variability of the Sun's...

    Sunspots could be seen by the Soho telescope in 2001 (l), but not this year (r) There are no sunspots, very few solar flares - and our nearest star is the quietest it has been for a very long time. The observations are baffling astronomers, who are due to study new pictures of the Sun, taken from space, at the UK National Astronomy Meeting. The Sun normally undergoes an 11-year cycle of activity. At its peak, it has a tumultuous boiling atmosphere that spits out flares and planet-sized chunks of super-hot gas. This is followed by a calmer period. Last...

The number of sunspots - cooler areas on the sun that appear dark against the brighter surroundings - dropped a thousandfold, according to some...
