Previous research could not accurately date the sea-level rise but now an Aix-Marseille University-led team, including Oxford University scientists Alex Thomas and Gideon Henderson, has confirmed that the event occurred 14,650-14,310 years ago at the same time as a period of rapid climate change known as the Bølling warming...
During the Bølling warming high latitudes of the Northern hemisphere warmed as much as 15 degrees Celsius in a few tens of decades. The team has used dating evidence from Tahitian corals to constrain the sea level rise to within a period of 350 years, although the actual rise may well have occurred much more quickly and would have been distributed unevenly around the world's shorelines.
Dr Thomas said: 'The Tahitian coral is important because samples, thousands of years old, can be dated to within plus or minus 30 years. Because Tahiti is an ocean island, far away from major ice sheets, sea-level evidence from its coral reefs gives us close to the 'magic' average of sea levels across the globe, it is also subsiding into the ocean at a steady pace that we can easily adjust for.'
...What exactly caused the Bølling warming is a matter of intense debate: a leading theory is that the ocean's circulation changed so that more heat was transported into Northern latitudes.
The new sea-level evidence suggests that a considerable portion of the water causing the sea-level rise at this time must have come from melting of the ice sheets in Antarctica, which sent a 'pulse' of freshwater around the globe. However, whether the freshwater pulse helped to warm the climate or was a result of an already warming world remains unclear.

And not an SUV or coal-fired power plant in sight....
Maybe carbon dioxide is not as much of a factor in planetary warming and/or cooling as once thought.
Could either A) a sudden surge of heat from the earth’s interior, released through geothermal vents or eruptions, or B) a sudden surge in the heat reaching the earth from the sun, due to the sun’s own heat release activity, have anything to do with the cataclysmic ice melting?
It takea an AWFUL lot of heat units to convert so much ice to liquid water. Check the textbooks on this.
But first he asked: “What’s an ark?”
That didn’t make sense to me either.
Lets see if my math is still up to par. A decade is ten years, ten decades would mean a hundred years, tens of decades loosely translated would equal to about 500 years so a few of those would equal to at least 2000 years......
Except of course at Tahiti.
I think what they are talking about is a catastrophic melt. Happening very quickly it would seem the water levels nearer the poles would raise faster than the levels closer to the equator. Something that would happen as white hot Venus comes cruising by on it's way to become planet number 2.
Which explains what happened to Atlantis. 2 giant waves of water, one from the South, one from the North meet at Atlantis. The enormous upthrust of water submerges the huge power crystal and it goes nova. When the water recedes, levels out, Atlantis is gone.
I just knew there was a reasonable explanation. :-)
I kinda like to stick to the Venus thing. A one time event. The thought of the dark side of the moon being a huge mirror (think ‘burning mirrors of Archimedes’) and that the aliens can spin the moon around and fry us like burning ants with a magnifying glass, or melting the poles just for the heck of it, frightens me. I don’t know why that is.
There is nothing to fear but fear itself. So be afraid. Be very afraid!
Ooh, and here’s another ... 3,600 x 4 = 14,400.
Just in case you needed to work that 2012 deal in somewhere along the way, lol.
The melting inland is known to have accumulated in spots, until the ice dams themselves melted, unleashing the meltwaters and producing (for just one instance) the Channeled Scablands.
:’) The article gives a figure of 350 years.
Or, as Plato said, “...the Acropolis was not as now. For the fact is that a single night of excessive rain washed away the earth and laid bare the rock; at the same time there were earthquakes, and then occurred the extraordinary inundation, which was the third before the great destruction of Deucalion. But in primitive times the hill of the Acropolis extended to the Eridanus and Ilissus, and included the Pnyx on one side, and the Lycabettus as a boundary on the opposite side to the Pnyx, and was all well covered with soil, and level at the top, except in one or two places...” and “...there occurred violent earthquakes and floods; and in a single day and night of misfortune all your warlike men in a body sank into the earth, and the island of Atlantis in like manner disappeared in the depths of the sea. For which reason the sea in those parts is impassable and impenetrable, because there is a shoal of mud in the way; and this was caused by the subsidence of the island...”
This was followed by the Younger-Dryas (12,800 - 11,500 ya) which was the coldest time of the last 20,000 years. The Diagram shows the spike at ~15,000ya. The world was usually a pretty cold place before ~12kya.
Pardon my cynicism but some times this $4!T just makes me want to puke!
In her Plato Prehistorian: 10,000 to 5000 B.C. Myth, Religion, Archaeology, Mary Settegast reproduces a table which shows four runic character sets; a is Upper Paleolithic (found among the cave paintings), b is Indus Valley script, c is Greek (western branch), and d is the Scandinavian runic alphabet.
Hmmm...I wonder if when they see a car traveling at a steady pace of 60 miles per hour down the road they assume that it has always been traveling that speed.
Technically, I suppose not but what's a few thousand years amongst friends??? In any case I meant to say during the time modern Man was dodging saber tooth cats and runaway wooly mammoth herds and the like, and living to tell about it.
IOW, this has nothing to do with the Noachian Deluge.
Really? When was it???
These are submerged formations. If the Noachian Deluge had submerged ‘em, they would now be above water.
“It takea an AWFUL lot of heat units to convert so much ice to liquid water. Check the textbooks on this.”
Try a bolide smacking down into where one of the great lakes exists today - that would certainly do it!
I KNEW I should have checked in earlier. Your reply probably makes perfect sense, so I'm going to claim a brain freeze due to misfiring synapses and call a time out because I can't even fathom what you're trying to say. Maybe the fog will clear overnight and I'll be able to respond with something approaching coherence in the light of day. G'night...
Being an old salesman I'm far from an expert but based on my observations alone I have an opinion about the state of science and academia generally. To the layman it looks like their sole purpose for being is to discount others' work. Much like lawyers, they expend their energies arguing their cases in academic courtrooms. Full of sound and fury but signifying nothing. They're mostly hacking at the branches in an effort at relevance. Job security.
No offense intended for those few who are pursuing noble causes and genuine science; whomever and wherever they may be.
I entertained notions of significantly revising and extending my remarks then thought, WTH!
Myths can be useful, but as they don’t come with dates, it is unusual for them to be useful for dating catastrophic events.
In “Noah’s Flood”, Ryan and Pitman cite an ancient flood myth from the northern Aegean, then claim (without basis) that it must have originated from the Black Sea flood, and that the ancestors of the carriers of that myth had to move, wound up settling on the Aegean, subsequently (and most conveniently) forgetting where the event took place while still remembering the event in some detail.
Yes, the Pleistocene / Holocene boundary has been dated to about 10,500 years ago, IOW, not very far off the time Plato gave for the destruction of Atlantis, a myth that may have begun with Plato rather than having arrived in Greece via Solon’s supposed visit to Egypt.
Yes, it is widely accepted that large floods from glacial meltwater has happened a number of times in human times.
Science is a method, rather than being a body of knowledge. Knowledge increases, and comes from experience as well as the Aristotlian syllogism. Stuff that is disproved is discarded in favor of something else.
IOW, don’t project the acts and attitudes of people who reject the scientific method and the knowledge derived by it onto practitioners and students of the sciences.
The scientific community doesn’t have a trademark after it, but that did help set the tone for your old, tired tirade.
I won't bore you with the long list of "junk" science perpetrated under the aegis of government funding. You're familiar with it, or should be. As in the days of Galileo, government is now the church that persecutes those who practice real science outside the accepted paradigm or conventional wisdom. They're on their own while the faithful feed at the government trough. Do you disagree with that?
