Haha ;)
There’s no gradualist mechanism that can cause glaciation, so, no, Milankovitch’s model is wrong.
I wonder what connection, if any, there is between the 6th century cold period and the 7th century rise of Islam.
As the Roman Empire failed due to weather and political corruption it was no longer a force of power in the Eastern Mediterranean and Islam ran wild after the collapse. But the Roman Empire was already in decline before Islam existed.
Please elaborate on your post.
The cycle is of three components The Malkovich cycle, also known as Milakovich cycles, refers to the three variations in Earth's orbit that influence its climate over long periods. These cycles have different periods: about 100,000 years for orbital eccentricity, 41,000 years for axial tilt (obliquity), and 26,000 years for precession.
Dependent on how the three componets line up is what gives of ice ages and the weather we enjoy now.
Doesn’t matter. That kind of ice generation requires an active hydrologic cycle, which is exactly what stops dead in conditions cold enough to prevent melt of ice and snow during summer months.
It used to be thought that Antarctica must have x amount of precipitation, and the first big year-round structure was something like a geodesic dome, which would stand up for many years against the snow load. Turns out, no snow load developed because the continent has the least precipitation on Earth.
And that’s with a world with a working hydrologic cycle.
Islam is entirely a political cult, sprung from either a single person, or from some small group which led to a later group of ad hoc theologists who invented a single founder.
This reminds me a bit of Lycurgus, the supposed lawgiver of ancient Sparta — he was said to set up his legal code, then said to obey it without changes until he got back from Delphi, then went off and starved himself to death.
There’s not much Spartan literature (they don’t seem to have been readers, authors, or artists), but the oldest surviving work contains zero about him. He was probably invented as a supporting myth for their pretty hideous political system.
If the cold period began in 500 A.D., it was too late to bring down the Western Roman Empire. Romulus Augustulus, the last official Western Roman Emperor, was deposed in 476. By the 500s, the last people claiming to be Western emperors were gone, except for the local king of a mini-state in western Algeria. It looks like the Eastern Roman Empire WAS badly affected by the colder weather and Justinian’s plague, but I figured we all believed in that by now.
Yup. Plus, the Roman/Byzantine Empire didn’t fall until 1453. :^)
