Disaster that struck the ancients
The pharaohs of the Egyptian Old Kingdom had built the mightiest legacy of the ancient world - the pyramids at Giza. But after nearly a thousand years of stability, central authority disintegrated and the country collapsed into chaos for more than a 100 years.
What happened, and why, has remained a huge controversy. But Professor Fekri Hassan, from University College London, UK, wanted to solve the mystery, by gathering together scientific clues.
His inspiration was the little known tomb in southern Egypt of a regional governor, Ankhtifi. The hieroglyphs there reported "all of Upper Egypt was dying of hunger to such a degree that everyone had come to eating their children".
Dismissed as exaggeration and fantasy by most other Egyptologists, Fekri was determined to prove the writings were true and accurate. He also had to find a culprit capable of producing such misery.
Stalactites and stalagmites
"My hunch from the beginning was that it had to do with the environment in which the Egyptians lived." Fekri felt sure the Nile, the river that has always been at the heart of Egyptian life, was implicated.
He studied the meticulous records, kept since the 7th Century, of Nile floods. He was amazed to see that there was a huge variation in the size of the annual Nile floods - the floods that were vital for irrigating the land.
But no records existed for 2,200BC. Then came a breakthrough - a new discovery in the hills of neighbouring Israel. Mira Bar-Matthews of the Geological Survey of Israel had found a unique record of past climates, locked in the stalactites and stalagmites of a cave near Tel Aviv.
What they show is a sudden and dramatic drop in rainfall, by 20%. It is the largest climate event in 5,000 years. And the date? 2,200 BC.
As Israel and Egypt are in different weather systems, Fekri needed evidence of some worldwide climate event to link this to the collapse of the Old Kingdom. And the evidence came out of the blue.
Geologist Gerard Bond, of the Lamont-Doherty Earth Observatory at Columbia University, US, looks for climate evidence in the icebergs of Iceland. As they melt on their journey south, they leave shards of volcanic ash on the ocean floor.
Dry lake
How far they travelled before melting tells him how cold it was. Cores of mud from the ocean floor revealed to him regular periods of extreme cold - mini ice ages - in Europe every 1,500 years, and lasting 200 years. And one mini ice age occurred at 2,200 BC.
Fekri Hassan: Looked at lake-bed cores
Gerard's colleague, Peter deMenocal, looked at climate records for the rest of the world at exactly the same time. From pollen records to sand, the story was the same - a dramatic climate change from Indonesia to the Mediterranean, Greenland to North America.
Scientists were confirming everything Fekri believed - severe climate change causing widespread human misery 4,200 years ago, misery we are only now learning about for the first time.
Back in Egypt, Fekri wanted to put the last piece of the puzzle in place. He wanted direct evidence of this severe climate change in the Nile. And he found it drilling cores in a large lake that had been fed by a tributary of the Nile in ancient times.
He discovered in the critical period, as the Old Kingdom collapsed, the lake had dried up completely - the only time in the whole history of this lake that this had happened. At last, Fekri felt he had proved that the writings on Ankhtifi's tomb were really true. It was nature that had driven people to desperation.
It's been at it for 11.5 years now. (You're welcome)
FWIW, I think Maceman’s remark had a lot of merit.

Bump :)
Still going strong.
Chevron 7 is locked and holding.
Thrilled that there are a bunch of us from back then, that still support FR.
Blessings!
Yup. Still here after all these years.
This was a good thread/subject.
gleeaikin made a lot of (I think) good connections.
Hold on there, Pilgrim, the smart folks at Twitter, Facebook, Google (and probably Tik Tac) have banned Milankovitch Cycles as wrong, exceptionally wrong, and most sincerely wrong since they would be misinformation concerning a preposterous natural cause for periodic global climate variation. These interpretations, while having mathematics and testable fossil evidence, nonetheless must be Banned to prevent Government Control Hesitancy and to not promote Irrational Economic Exuberance. The Great Reset, you know. (Maybe the Ancients saw and feared the REAL RESET of millions of kilotons of icy rock)
