Climate variations have influenced the agricultural productivity, health risk, and conflict level of preindustrial societies. Discrimination between environmental and anthropogenic impacts on past civilizations, however, remains difficult because of the paucity of high-resolution palaeoclimatic evidence. Here, we present tree ring–based reconstructions of Central European summer precipitation and temperature variability over the past 2500 years. Recent warming is unprecedented, but modern hydroclimatic variations may have at times been exceeded in magnitude and duration. Wet and warm summers occurred during periods of Roman and medieval prosperity. Increased climate variability from ~AD 250 to 600 coincided with the demise of the Western Roman Empire and the turmoil of the Migration Period. Historical circumstances may challenge recent political and fiscal reluctance to mitigate projected climate change.

More climate hysteria disguised as policy-neutral scientific inquiry.
It was all those damn diesel powered chariots.
No on “BCE” and “CE.” It’s “BC” and “AD.”
If only the Left were right, and former empires did fail because of the weather...
But then, the Left couldn’t gasp any other reason for it, so I’m sure they’ve bought off on the global warming angle 100%.
The Left continues to impress, how dumb can a human being actually be? New records seem to be set all the time.
Global warming might be good for world peace.
The abstract would have been more pc if they had used CE (common era) instead of AD.
So preventing climate change is really the desperate act of a hegemonic elite obsessed with clinging to power?
What a bunch of gobbledegook to avoid the obvious “inconvenient truth” (for the global warming crowd, that is), that warmer weather means better crops and prosperity, and cold weather leads to famine and social disruption.
Those Roman Chariots were one of the worst creators of global warming. It sure makes me feel better to know that they are thing of the past.
Funny, I would have guessed several hundred years of autocratic leadership, often by mental incompetents, bankruptcy, a declining birthrate, disease, and constant warfare...but maybe those were cool years too.

The real story is that Europe was deeply in trouble before the weather changed for the worse in the mid 1300’s AD.
Italian bankers in Florence and Venice, primarily the Bardi and Peruzzi families had ruled over Europe for 150 years. You know, he who holds the gold, makes the rules. These banksters put the monetary screws to kings and nobility of Europe. Their greed and lending practices led to both France and England defaulting on their national debt. The bankers began having severe financial problems, so they tightened the screws on credit, put the squeeze on debtors.
As they say, some things never change, what goes around comes around.
The bankers squeezed. Feudal nobility was in debt to their eyeballs and they put the squeeze on the poor downtrodden serfs, raising tax levels to a point where the serfs could not feed their families, could not afford to borrow from “the company store” to buy seed to plant the following year. I believe it was winter 1341 or thereabouts when it got so bad, they ate what little supply of seed they had for planting the following spring.
Mass starvation and famine set in. In the space of 7 years half the population died.
Then things really went downhill, the weather changed and freezing cold and dampness set in. TSHTF.
That statement, taken out of context, could easily be misinterpreted.
