The More Things Change….

Solar eclipse 8-21-2017 – Photo by Ex-PH2

…the more they stay the same.

This article is in regard to “the end of Roman Warm Period”:  http://www.co2science.org/subject/r/summaries/rwpeurope.php

There is an active volcano in continuous eruption under surveillance by the Japanese volcano people. They are keeping a weather eye on it.  https://www.volcanodiscovery.com/ebeko/news/106914/Ebeko-Volcano-Volcanic-Ash-Advisory-ERUPTION-AT-202007210510Z-FL100-EXTD-SE-REPORTED-OBS-VA-DTG-2105.html

Ebeko is producing a high volume of ash and gases which are rising to over 30,000 feet. It hasn’t reached us yet, but give it time to float around up there.

Stromboli has also erupted this morning with a very gassy, ash-laden burp. More info is available at https://www.volcanodiscovery.com/stromboli/news.html

This article from WUWT adds more information about the influence of active volcanism over prolonged periods of time. It’s the ash volume along with the altitude it reaches that is the concern. Enough particulates reaching a high altitude will do more than clog jet engines. Once these particulates, which are volcanic “dust”, if you will, reach an altitude at the stratospheric level, they can and will block the sun’s light and heat. This happens during solar eclipses, too.  People going to totality parties consistently report drops in temperature, and during the last total solar eclipse, when I was out on my front steps with a camera, getting that photo, the air was noticeably cooler than it had been in the morning. If the sun is inactive now, as it has been since 2008, then it is producing less heat than normal, which may explain our “wacky weather” and fewer hurricanes.  The last el Nino event ended in 2016, and another one is not expected any time soon.

During the Roman Warm Period, the Alaskan volcano Okmok in the Aleutian Islands chain erupted continuously for 2 (two) long years, altering solar influence and weather patterns in the northern hemisphere. Evidence has been found in several places, including a cave in China. A continuous eruption for two years, producing a lot of ejecta that reach the upper atmosphere, will substantially block the amount of sunlight reaching the planet’s surface.

That eruption in 43AD ended the Roman Warm Period, shortly after Gaius Iulius Caesar was assassinated. It did not stop the expansion of the Roman Imperium into Europe, which had begun well over a century earlier, and may indeed have been partly responsible for Rome’s increased efforts at northward and eastward territorial acquisitions and expanded trade.

The Roman government, through its military branch, had been pushing the native tribes such as Gauls and Bretons, et al., further and further north into the British Isles for over 500 years. Some Bretons stayed in France, mostly in what is now Brittany. And the Breton language is still spoken, and is thought to be a form of Gallic, which became Irish Gaelic and Scots Gaelic. Those are two different dialects of the same language, with different pronunciations and rules of grammar.  http://factsanddetails.com/world/cat56/sub368/item2092.html

The Picts (Scots), those guys who were trained to fight by the women in the family and went into battle buck naked and painted blue, were already living there. You can probably imagine the resentment they felt at these invading refugees.

(You do understand that this is a shortened version of the story, right?)

The point is that the Roman government needed funds in the form of shiny gold and shiny silver and funds from other stuff, as well as the tin that could be imported from what is now Wales and Cornwall. Copper came from Cyprus. While the Bronze Age had ended some time earlier, any weapon that would not rust was valuable.

The end of the Roman Warm Period may have had more to do with Rome’s expansion than anything else.

Conquering foreign tribes or populations means that you can tax them and trade with them. Taxes go to the government, and at the time, the Roman Empire was one of the wealthiest governments in the known world.

Rome did, in fact, impress the Chinese enough to persuade the Chinese government to not pick fights with them, as Rome was, in fact, a major trading partner with China going back to the BCE 200s, even though Parthia (Persia/Middle East) and the Kushans were trying to retain control over what is now the Old Silk Road. (Taxes again! Fees for travel! Tax on imported goods!) Does any of this sound familiar?

Why is it called the Old Silk Road? Because silk fabric back then was a major commodity in several countries, including Rome and Parthia, and that ancient route was a major highway for traders, just as our national highways are major routes for commercial traffic now.

Is there a parallel between then and now? Absolutely, there is. The Late Bronze Age populations were heavily involved in trade around the eastern Mediterranean until some event happened, which may have been invading refugees from western Europe escaping warfare and diseases, as well as an unexpected change in the weather patterns of the Mediterranean.  Much later after that, the Roman Warm Period came to an abrupt end when Okmok began its eruptions and outgassing with ejecta, and while Rome still prospered, it began to slowly decline, with other factors also being involved, one of them being high traffic trading with countries like China and Parthia.

It boils down to the cash in the cash drawer. Trade with foreign powers will make both parties wealthy, and possibly one may become wealthier than the other.  Always follow the money, people. Always follow the money.

Welp, wasn’t sure if this post was to be all about sciencey stuff, gramer/lit astrophysics, climate change, geology, history, geography, economics, civics, military tactics, business, cartography, health, metalogoly, undocumented refugees, or sex ed. It was all very interesting tho and I enjoyed it. All that was missing was Home EC. We did miss our Monday Recipe. Thought I’d let that slide just because someone has been under the weather?

Full disclaimer. I have had something run amok during a warm period, have multiple eruptions of ejecta, but when it abruptly ended the decline was quite rapid.

Well you did a fine job on covering everything but my nap. Matter fact, the linkys were keeping me occupied thru Gunsmoke re-runs and my nap time got moved out.

Most of my “studies” of North American Climate Change and the effects on the Hoomans has been Michael and Kathleen O’Neil Gear’s Historical Novels on the ancestors of the Mound to Aztec/Inca/Mayan times. We have, locally, a smaller version of what y’all have at Cahokia Mounds. Spent most of the day at Cahokia back in ’15 and still didn’t see all I wanted to. That and the Great Inland Sea that is now the Great Plains has a lot of evidence of the millenia. Fort Rob in NE has an excellent ongoing dig at the Trailside Museum showing the march of the critters, the people, and how the different weather ages came about.

You do remember that I click on and read every linky here? Every.Damn.One.

See below. Cooking rocks for metal.

Bronze was very expensive, essentially a precious metal. This has to do with the relative scarcity of Tin. Both Tin and Copper are relatively easy to extract from ore. An ordinary wood fire will work well enough for obtaining some useful amounts. Thus it was easy to obtain Bronze from materials, but hard to find its raw materials.

It was the metal of kings and wealth.

During the bronze age, iron was unobtainable, other than by meteorite. Then, someone figured out how to make very hot fires, using forced air or channeled wind to boost fire, and then how to expand on that with charcoal or coal. Then someone started heating up rocks to see what other stuff might be cooked out.

And Iron is absurdly common, once you know how to cook it out of ore.

Bronze remained in use, but was very much luxury stuff. Iron became much cheaper substance.

Then, someone figured out how to add stuff to iron, like a bit of carbon, and the resultant steel again revolutionized metalworking.

Then, a man named Carnegie spent a lifetime turning steel so cheap we could make throwaway toys and cans from it.

Yeah, but taxation of the silk road wasn’t that straight forward.

The vast majority of goods changed hands many times along the silk road. Don’t think of it as a Han or a Roman dude with a donkey going all the way from Europe to East Asia.

Most merchant dudes just took the goods to the next trading town over, where they would sell it to another merchant, who would in turn move the goods to the next trade emporium along the route.
