Scientist says volcanic eruption behind ‘perfect storm’ that kicked off Dark Ages

TORONTO — American paleoecologist Dr. Robert Dull believes he’s pretty much solved the mystery behind a catastrophic global climate change event from the sixth century.
As the new History series “Perfect Storms” shows, Dull has found solid circumstantial evidence that an eruption at El Salvador’s Lake Ilopango volcano was the cause of the so-called Dust Veil of AD 536, when a thick dust and ash cloud over the Northern Hemisphere cooled parts of the Earth and led to millions of deaths.
It’s perhaps a major breakthrough for experts who have long wondered whether the dust veil was a result of a volcanic eruption, a meteorite or a comet that slammed into Earth.
“I hate to say that it’s 100%, but it’s 99% in my mind done [that] Ilopango was the cause of the AD 536 climate cooling that lasted for at least two years, globally, but definitely as much as a decade in terms of cooler temperatures, crop failures across the globe, and a major catastrophe that killed millions of people,” Dull, senior research fellow in the Environmental Science Institute at the University of Texas at Austin, said in a recent interview.


Believing when there is no compelling evidence is a mistake.  The idea is to withhold belief until there is compelling evidence and if the universe does not comply with our predispositions, okay, then we have the wrenching obligation to accommodate to the way the universe really is.  - Carl Sagan

Who is more humble, the scientist who looks at the universe with an open mind and accepts whatever the universe has to teach us or somebody who says everything in this book should be considered the literal truth and never mind the fallibility of the human beings involved in the writing of this legend - Carl Sagan

Cool, not for the millions of deaths.  But cool.

Just goes to show you how delicate the balance of life really is.  Too cold or too hot and people will die.

Neat article! Thanks for posting. :tu:


Perfect Storms, premiering on Monday in Canada, investigates major natural disasters that have changed the course of human history — many from hundreds of years ago that aren’t well known — and presents them through impressive CGI technology and dramatic re-enactments.
In Dull’s episode called “Dark Age Volcano” — airing April 15 — he finds a tree in El Salvador that he believes was living at the time of the eruption of Ilopango, one of the biggest volcanoes in central America, around 1,500 years ago.

Will this be airing in the US as well?

There is a growing consensus that the cause of the "dim sun" was volcanic in origin, but there are at least three different opinions about which volcano it was.  Candidates are Krakatoa, Ilopango and another South America volcano whose name I don't remember - San Something.  Tamboura and Vesuvius produced eruptions about the same time, though it is doubtful that they were big enough and Tamboura may not have been at the right time.

Little Fish is never going to believe this because the dating was confirmed by Keith Briffa using dendrochronology and according to LF, Briffa lies and dendrochronology is about the same as voodoo.  OK -  Druidism - dendrochronologists worship trees.

Anyway, I have some trees to worship.  Catch ya later.
