“This is further evidence that the Younger Dryas climatic onset is an extreme global event, with major consequences on the animal life and the human life at the time”. The full paper is available to read online: “ Sedimentary record from Patagonia, southern Chile supports cosmic-impact triggering of biomass burning, climate change, and.   A major global climate event called the Younger Dryas dramatically affected local environments and human populations at the end of the Pleistocene. This volume is the first book in fifteen years to comprehensively address key questions regarding the extent of this event and how hunter-gatherer Pages:

  That condition answers all the climatic requirements for the Younger Dryas, worldwide. The nearly year warming period prior to the Younger Dryas had repopulated the plains of North America with trees. There was plenty to burn. (The dry High Plains east of the Rocky Mountains did not come into existence until the catastrophe.).   A meteorite imp years ago caused the extinction of the North American megafauna and triggered the Younger Dryas cooling event. Several clues point to .

Data on environmental change at the Younger Dryas-Preboreal transition and during the early Holocene are reviewed with particular reference to evidence from Poland and neighbouring areas of central Europe. Various factors modified the rate of environmental change during the general warming and reforestation.   The Younger Dryas (named after Dryas octopetala, a flower that grows in cold conditions) strongly interrupted the rapid warming of Earth (see figures 1 and 2). Evidently, it prevented the global mean temperature from rising to its normal maximum value.

Younger Dryas, also called Younger Dryas stadial, cool period between roug years ago that disrupted the prevailing warming trend occurring at the end of the Pleistocene Epoch (which lasted from million to 11, years ago).

The Younger Dryas was characterized by cooler average temperatures that returned parts of the Northern Hemisphere and other regions to ice age. The Younger Dryas boundary lies at the base of the YD black mat.

(Comet Research Group / Author Provided) Magnetic grains, often too small to see with the naked eye, can be formed from iron, common in asteroids and comets, vaporizing at very high temperature, in a massive explosion for example, and then condensing into microscopic magnetic iron.

Greenland ice cores also show ammonium (NH 4 +) increases during the Tunguska event and the Younger Dryas ().While biomass burning is implicated for the Younger Dryas increase (e.g., Firestone et al., ), the amount of burning during the Tunguska event is too small to account for the ammonium increase of > ppb (Melott et al., ).Another alternative, involving direct ammonium Cited by: The End of the Younger Dryas.

After the PETM, the Younger Dryas (named after the cold climate plant Dryas octopetala) is perhaps the best-known example of deep-time rapid climatic change. Beginning ab years ago, the climate began to slowly warm up, but then there was a sudden lapse back into cold conditions followed by a very rapid.

The Younger Dryas (YD, c. – ka) represents the last return to cold, stadial conditions prior to early Holocene warming and is characterized by abrupt climate change. It marks the final phase of Termination I and is also referred to as Greenland Stadial 1 (GS-1).

The Younger Dryas Impact hypothesis describes a possible cause for the cataclysmic scenario. In this article, we will explore the evidence that the earth was the victim of a very recent and life-shaking cosmic impact. The Prehistoric end of the Ice-Age and the great flood.

The Younger Dryas was a period that lasted from 12 – 11 years. The period in history coincides with the climatic event of the Younger Dryas. What was the Younger Dryas. The Younger Dryas was an earth period that began roughly years ago and finished years ago.

These years mark the transition out of the last great ice age. It was a period where the earth as a very different place. A well researched book about the Younger Dryas event. Many recent research came out to confirm the thesis of this work, but the material in the book is still fundamental for a basic understanding of what may have happened even if one can agree or disagree on the Supernova hypothesis before the main event.

Younger Dryas is a ficitional novel set at the onset of the younger dryas glacial freeze—12, years ago. The book is based on research from Graham Hancock’s books.

It’s 10, BC. A star has become trapped in earth’s orbit and broken apart. In less than a season the earth will collide with a gauntlet of debris. Carnage is guaranteed. Deadly Voyager website.

I was excited today to order a newly published book concerned % with the Younger Dryas Impact Event. The author is long-tenured and highly respected geologist, college president, museum director and writer, Dr. James Lawrence book can be purchased from Amazon here.

I will devour the book and return with a review. Others have postulated that the Younger Dryas event was caused by a meteor impact. Evidence for this theory includes carbon rich soil layers that mark the start of the Younger Dryas event containing nanodiamonds, metallic microspherules, carbon spherules, magnetic spherules, iridium, charcoal, soot, and fullerenes enriched in helium   These boulders and associated glacial erratics were dumped by the retreat of the Okanogan ice lobe and, thus, cannot possibly be associated with a Younger Dryas megaflood.

Finally, in Graham’s latest book, Randall Carlson talks about the Palouse Loess as having dropped from the sky as muddy rain as the result of a Younger Dryas Impact.

- Younger Dryas is characterized by abrupt changes in climate - oxygen isotope from the Greenland ice core shows an abrupt temperature d years ago, years of cool climate, and sudden warm years ago (not just a single climatic event). (The Younger Dryas is an anomalous cold period that occurred ab, years ago during the transition from glacial to inter-glacial conditions.) He spent the last part of the talk highlighting some purported evidence (e.g., Gobekli Tepe, the Sphinx) supporting the claim that refugees from Atlantis occupied the Near East after fleeing.

It is a superb book and has absolutely convinced me there were comet airbursts at the Younger Dryas. And the airbursts probably killed the megafauna which in turn, caused the Clovis culture to cease existence (partly by diminishing human numbers but also because there was no need to have Clovis spearheads that could kill nonexistent megafauna).

Greenland ice-core records provide an exceptionally clear picture of many aspects of abrupt climate changes, and particularly of those associated with the Younger Dryas event, as reviewed here.

Well-preserved annual layers can be counted confidently, with only ≈1% errors for the age of the end of the Younger Dryas ≈11, years before by: In this study, diatom record from the sediments of Yunlong Lake, in the southeastern Tibetan Plateau, was used to reconstruct snowfall during the Younger Dryas (YD).

This presentation discusses the onset of the Younger Dryas and the conditions that caused it to last 1, years. Three different hypotheses are discussed. I was excited today to order a newly published book concerned % with the Younger Dryas Impact Event.
