Fingerprint Of A Global Cataclysm 12,800 Years Ago
The graphic shows the vast swathe of our planet that geologists call the Younger Dryas Boundary Field. Across this huge “fingerprint” spanning North America, Central America, parts of South America, most of Europe and parts of the Middle East as well, the tell-tale traces of multiple impacts by the fragments of a giant comet have been found. Some of these fragments, were TWO KILOMETRES or more in diameter and they hit the earth like a blast from a cosmic scatter-gun around 12,800 years ago. This was near the end of the last Ice Age, from which our world had been emerging into a pleasant warming phase, but the impacts set in train a kind of "nuclear winter" and plunged the planet back into a period of deep cold and darkness that lasted until around 11,500 years ago. It is this period of extreme cold that is referred to as the Younger Dryas (after a characteristic Alpine tundra wildflower, Dryas octopetala) but it is only now, with conclusive evidence of the comet impact, that we can be sure what caused it. For the past seven years academics have been involved in such an intense dispute about whether or not a comet impact actually occurred 12,800 years ago that the implications of what it might have meant for the story of civilisation have not yet been considered at all. But every attempt to refute the impact evidence has in turn been refuted and the case for the Younger Dryas comet is now so compelling that it is time to widen the debate. It is clear now that some of the largest fragments of the comet hit the North American ice cap, which was still a mile deep 12,800 years ago, and caused cataclysmic flooding (I had the opportunity to explore some of the extraordinary effects of this on the ground in September 2014 when I drove from Portland, Oregon, to Minneapolis, Minnesota, with catastrophist researcher Randall Carlson). Simultaneously other large fragments hit the northern European ice cap with the same cataclysmic effects. The result was a global disaster that lasted for 1,300 years. It is, I believe, the "smoking gun" that made us a species with amnesia and wiped out almost all traces of a former high civilisation of prehistoric antiquity. But there were survivors, who preserved at least some of the knowledge of the civilisation that had been destroyed with the intention of transmitting it to future generations, so it is not an accident that the first traces of the re-emergence of civilisation, in the form of the earliest known megalithic architecture and the re-promulgation of agricultural skills, occur at Gobekli Tepe in Turkey 11,500 years ago — a date that coincides exactly with the end of the Younger Dryas and the return to a more congenial global environment. Everything we have been taught about the origins of civilisation occurs AFTER 11,500 years ago — in other words AFTER the radical punctuation mark of the Younger Dryas. It is what happened before that we desperately need to recover. These are amongst the mysteries that I am exploring in Magicians of the Gods, the book that I have been researching for the past three years and am now in the midst of writing.

Did a Comet Hit Earth 12,000 Years Ago?
Nanodiamonds found across North America suggest that major climate change could have been cosmically instigated
Roughly 12,900 years ago, massive global cooling kicked in abruptly, along with the end of the line for some 35 different mammal species, including the mammoth, as well as the so-called Clovis culture of prehistoric North Americans. Various theories have been proposed for the die-off, ranging from abrupt climate change to overhunting once humans were let loose on the wilds of North America. But now nanodiamonds found in the sediments from this time period point to an alternative: a massive explosion or explosions by a fragmentary comet, similar to but even larger than the Tunguska event of 1908 in Siberia.
Sediments from six sites across North America—Murray Springs, Ariz.; Bull Creek, Okla.; Gainey, Mich.; Topper, S.C.; Lake Hind, Manitoba; and Chobot, Alberta—yielded such teensy diamonds, which only occur in sediment exposed to extreme temperatures and pressures, such as those from an explosion or impact, according to new research published today in Science.
The discovery lends support to a theory first advanced last year in that some type of cosmic impact or impacts—a fragmented comet bursting in the atmosphere or raining down on the oceans—set off the more than 1,300-year cooling period in the Northern Hemisphere known as the Younger Dryas for the abundance of an alpine flower's pollen found during the interval.
The cooling period interrupted an extended warming out of an ice age predicted by slight changes in Earth's orbit (known as Milankovitch cycles) that continues today. And it remains an unexplained anomaly in the climate record.
But a series of cometary fragments exploding over North America might explain a layer of soil immediately prior to the cooling containing unusually high levels of iridium—an element more common in cosmic wanderers like meteoroids than in Earth's crust. Paired with the fact that this layer occurs directly before the extinction of at least 35 genera of large mammals, including mammoths, it is strong circumstantial evidence for a cosmic event.
"Very strong impact indicators are found in the sediments directly above, and often shrouding in the case of Murray Springs, the remains of these animals and the people who were hunting them," says archaeologist and study co-author Doug Kennett of the University of Oregon in Eugene, the son in the father–son team helping to advance the new impact theory. "Is it a comet? Is it a carbonaceous chondrite? Was it fragmented? Was it focused? Based on the distribution of the diamonds, it was certainly large scale."
Preliminary searches further afield—Europe, Asia and South America—have turned up similar minerals and elements in sediments of the same age, Kennett says, and his own work on California's Channel Islands tells a tale of a massive burn-off, followed by erosion and a total change in the flora of the region.
"It's consistent with a fragmentary body breaking up with air shocks and possible surface impacts in various parts of North America. It could be above the ice sheet or offshore in the ocean," he says, explaining why no impact crater(s) has been found to date. "Immediate effects on the ground include high temperatures and pressures triggering major transformations of the vegetation, knocking trees over but also burning."
And that would make the climate shift of the Younger Dryas a closer cousin to the massive asteroid impact that wiped out the dinosaurs 65 million years ago. "This is an event that happened on one day," Kennett notes. "We're going to need high-resolution climate records, archaeological records, paleontological records to try to explore the effects."

Ancient carvings show comet hit Earth and triggered mini ice age
Ancient symbols carved into stone at an archaeological site in Turkey tell the story of a devastating comet impact that triggered a mini ice age more than 13,000 years ago.
Evidence from the carvings, made on a pillar known as the Vulture Stone, suggests that a swarm of comet fragments hit the Earth in around 11000 BC.
One image of a headless man is thought to symbolise human disaster and extensive loss of life.
The site is at Gobekli Tepe in southern Turkey, which experts now believe may have been an ancient observatory.
Computer software was used to match carvings of animals – interpreted as astronomical symbols – to patterns of stars and pinpoint the event to 10950 BC.
Other evidence for the impact from a Greenland ice core suggests roughly the same time frame.
The cataclysm ushered in a cold climate lasting 1,000 years and is likely to have resulted from the break-up of a giant comet in the inner solar system.
'Worst day in history'
"It appears Gobekli Tepe was, among other things, an observatory for monitoring the night sky," says lead researcher Martin Sweatman, from the University of Edinburgh’s School of Engineering.
"One of its pillars seems to have served as a memorial to this devastating event – probably the worst day in history since the end of the Ice Age."
The carvings appear to have remained important to the people of Gobekli Tepe for millennia, indicating an event that had a very serious and long-lasting impact, say the scientists.

A number of the pillar symbols suggest that long-term changes in the Earth’s rotational axis were recorded by the early astronomers using an early form of writing.
The discovery also supports the theory that Earth experiences times when comet strikes are more likely, due to the planet’s orbit intersecting with rings of cometary fragments.
