If he did, he was a Krak-Pot, since the volcano's famous eruption happened in 1883......
I think maybe the scientist’s conclusion was that Krakatoa initiated what we consider the dark ages, it wasn’t so recent as the “little ice age” in the top article.
The supposition was something like this:
First off, he went to some length to determine the date of a massive eruption at Krakatoa - I think it was around 500 AD. The resulting mess of particulates in the atmosphere actually darkened the sky around the globe for several years - and dropped average temperatures.
Crops were seriously impacted, which brought economic hardship, leading to social chaos and eventual ruin.
It probably seems a bit like Coast to Coast AM fare, but the supposition was pretty well supported. Wish I remembered more details.
It was on one of those Discovery channel, or PBS specials where they walk through a series of scientific discoveries to an interesting scientific conclusion about history - not like the global warming nonsense, but real science.
Like another - a fjord in Alaska which was for a long time known to have somehow suffered periodic 100-yard high tsunamis for unknown reasons, which eventually was determined to have been caused by massive rock slides from a cliff at the foot of the fjord, which dropped tons of rock thousands of feet into the water of the fjord, generating a terrible wave.
It’s like the Bermuda Triangle hypothesis, that the cause is vast Methane deposits under the steep sedimentary seabed under that part of the Atlantic - which when released by undersea slides of that sedimentary mud, can remove bouyancy from the sea and actually sink huge ships - and change the oxygen mix of the air above enough to cause internal combustion airplane engines to cease operation. Thus explaining the mysterious disappearance of planes and ships in the area.
It just made abundant sense at the time. I bought the idea anyway.
