Climate change caused empire's fall, tree rings reveal
Cornell Chronicle ^ | May 14, 2014 | Linda B. Glaser

Posted on 05/31/2014 6:06:31 AM PDT by SunkenCiv

A handful of tree ring samples stored in an old cigar box have shed unexpected light on the ancient world, thanks to research by archaeologist Sturt Manning and collaborators at Cornell, Arizona, Chicago, Oxford and Vienna, forthcoming in the June issue of the Journal of Archaeological Science.

The samples were taken from an Egyptian coffin; Manning also examined wood from funeral boats buried near the pyramid of Sesostris III. He used a technique called “dendro radiocarbon wiggle matching,” which calibrates radiocarbon isotopes found in the sample tree rings with patterns known from other places in the world that have already identified chronologies, such as the long European oak chronology or the bristle cone pine trees of North America.

Because the dating was so precise – plus or minus about 10 years – it helps confirm that the “higher” Egyptian chronology for the time period is correct, a question scholars have hotly debated.

But the samples also showed a small, unusual anomaly following the year 2200 B.C. Paleoclimate research has suggested a major short-term arid event about this time.

“This radiocarbon anomaly would be explained by a change in growing season, i.e., climate, dating to exactly this arid period of time,” says Manning. “We’re showing that radiocarbon and these archaeological objects can confirm and in some ways better date a key climate episode.”

That climate episode, says Manning, had major political implications. There was just enough change in the climate to upset food resources and other infrastructure, which is likely what led to the collapse of the Akkadian Empire and affected the Old Kingdom of Egypt and a number of other civilizations, he says.

“The tree rings show the kind of rapid climate change that we and policymakers fear,” says Manning...

I thought it was the ewoks of Endor but I suppose the big trees had something to do with it.

OK...rapid climate change happened some 4,000 years ago...So what...

Humm, so we are supposed to change our entire standard of living to attempt to stop something that has been occurring for eons...

Mann needs to lead the way, live in a hut like a bushmen did 4,000 years ago, I might pay attention...

A walk in the bulrushes produced one kind of leader, but the infamous “bushrushes” of today produced a small cohort of very different leaders.

Too bad they didn’t know to burn enough fossil fuels to provide a CO2 rich environment which would have allowed more food plants to survive with less water.

Feline radiocarbon wiggle match?

Ancient Egyptians who refused to accept the concept of Anthropogenic Global Warming were in de Nile.

Too many SUVs in ancient Egypt? Or maybe, juuuust maybe, the “scientific community” is actually wrong about the source of the modern “Climate Change”???? NAAAHHHH!!!

“Ancient Egyptians who refused to accept the concept of Anthropogenic Global Warming were in de Nile.”

Au contraire - Gorbul Warming caused the Nile flow to change which meant that those Gyppos were no longer in de Nile cause it changed.

Too many chariots can do that, Ya know?

I think that would require that the Earth rotate on an axis perpendicular to it’s plane of rotation. I don’t know how much carbon dioxide that would take.

Either the chariots, or the large amount of sacred Bull.

This has been reported in other literature

~2200BC ‘Major VOLCANIC eruption’. (possibly in/around Iceland, disrupting the North Atlantic and/or Arctic circulations).

Bitterly COLD winters & indifferent, occasionally poor summers.

It was the four barrel carbs on their chariots...

Basic misconception on your part: the chariots were lightweight and used for warfare. Four barrels of anything would have collapsed them.

The barrels of carbs--and proteins & fats, for that matter--were relegated to carts.
