Makes our current warming/cooling cycles seem puny.

15,000 to 11,000 years ago Earth experienced a series of climatic fluctuations... there was a short cold spell, known as the Younger Dryas, before the final warming and... end of the last ice age. Based on Greenland ice core data, the Younger Dryas began... 10,900 B.C., and its ending... circa 9700 B.C. and may have occurred within an incredible three years... I once hypothesized that comets were responsible. A comet hitting the land or a shallow ocean, or exploding above the land's surface, scattering dust and debris into the atmosphere, would cause global cooling... This pattern fits well with the cooling at 10,900 B.C. and there is evidence of a cometary explosion over North America at this time... comets hitting deep oceans were responsible. A comet might break the thin oceanic crust, releasing heat from the hot magma beneath. Vaporized and displaced water would rain down on Earth, and tsunamis would wash across coastal areas, warming the planet... [But] Plasma hitting the surface of Earth could heat and fuse rock, incinerate flammable materials, melt ice caps, vaporize shallow bodies of water creating an extended deluge of rain, and send the climate into a warming spell. The release of pressure that follows the melting of thousands-of-meters-thick ice sheets can induce earthquakes and even cause hot rock under pressure to melt and erupt to the surface as volcanoes... The plasma event of 9700 B.C. eradicated advanced civilizations and high cultures of the time, and... could be the basis for the nearly universal myth of a Golden Age, a time when beings on Earth had mental abilities far surpassing those of later times. The 9700 B.C. event may be the original basis for the Atlantis legends; the timeframe fits well with Plato's account.

Very nice, comprehensive thread on the glitch coming out of the Wisconsin Ice Age. Thanks!
I thought the hypothesis from the comment ( See # 10 on this thread ) made sense.
They could not take advantage of their success however because Obama traveled back in time and drove them off.
Man , ...there is just so much good stuff out there on these great internet sites.

It was all those SUV’s back then.
I assume that PH- Post Hegira would be the norm by now but Moslems are not all that clear just when H was and there are several date systems stemming from it. Choosing one would upset adherents of the others.
How about 14,000 Winters ago, or many moons have passed since....
An excellent run down of the complex climate changes after the end of the recent great Ice Age. Personally, I am inclined to think the several of the major ice ages were caused by major terrestrial events. The Long Valley and Yellowstone megavolcanic events over 700,000 and 600,000 year ago come to mind. On the other hand I would not be surprised if others were begun by major boloid events. I think Firestone et al give an excellent easy to read account of events that may have caused the Younger Dryas. As one comment points out there could have been several such events relatively close in time.
The great Chesapeake Meteor event around 34 million years ago was one of several in that period. A ten mile diameter crater was found of that age off Toms River, NJ. Also Popogai (sp?), a 60 mile diameter crater in Russia has that age. On the other hand while the most recent ice age began about 125,000 ya, around 74,000 ya the megavolcano Toba left a crater 18 by 65 miles and the charts show a major downturn in temperature for that period.
In Egyptian history there is a period of perhaps 200 years prior to 2,000 BC known as the First Intermediate Period, documented in the Ipuwer papyrus housed in the Leyden (sp?) Museum. Checking on craters, I found that there were a number of significantly large boloid craters (from 5 to 14 miles in diameter) in Argentina with the right age for that period. SC has reported on the 2 mile diameter crater found in the drained Iraq Marshes also about 2,000 BC.
Detail on the eruption of Laacher See Volcano in Germany, 12,900 ya is well described in Hans-Ulrich Schmincke’s book Volcanism (2004). This Plinian eruption was slightly larger than Pinatubo. In other words there are potential a number of potential interactive forces at work influencing the Younger Dryas.
While, I think that a lot more needs to be known and worked out scientifically about anthropogenic climate influence, I think the basic thing we have to realize is that there are a number of possible potential influence on climate. Since highly educated scientists tend to be experts on volcanoes, cosmic events, climate, archaeology, or ancient history, etc, we have lacked a fully functioning interdisciplinary approach to answering such complex questions. One of the things I love about both Catastrophism and GGG is that these sites bring together a number of gifted and curious amateur science sleuths.
But that's me.
I want a fixed date from SOMEWHERE. ANYWHERE works... Jan 1st, 1970 is special for me. 1340607344

Meh... Demand a fixed time constant. It's for the wimmen.

Thanks glee’.
