Historic Vids氏による、人類最悪の年、と他の例（氏のポストにはG訳を付けました）。過去に滅びていても不思議ではないな

2020 was a terrible year, but it's still far from being the worst in recorded human history. Here are a few bad ones: 1349 was the peak of the Black Death, which killed an estimated 75 to 200 million people in Europe, Eurasia, and North Africa. It is considered the deadliest pandemic in human history. 1520 was when smallpox spread across the Americas, killing an estimated 90% of the Indigenous population. It is estimated that 25 to 55 million people perished. 1918 was when the influenza pandemic killed an estimated 50 million people across the globe. As many as 500 million people were infected. These were all terrible years, but many historians believe that the absolute worst was 536 AD. According to medieval historian, Michael McCormick, "It was the beginning of one of the worst periods to be alive, if not the worst year." So what exactly happened in 536? Well for starters, a volcano erupted in Iceland, which dimmed the sun for 18 months, causing temperatures to decrease by 1.5 to 2.5 degrees Celsius. This led to the coldest decade (536 to 545) in 2,000 years, leading to crop failures and mass starvations in Europe, Mesopotamia, and China. In 540 there was another volcanic eruption, this time in Ilopango, El Salvador, which killed tens of thousands of people and decreased global temperatures once again. In 541, the Plague of Justinian began to spread throughout the Mediterranean Basin and would kill 35 to 55% of the population. The plague would greatly weaken the Byzantine Empire after devastating its capital, Constantinople. The natural disasters, crop failures, and the plague would go on to decimate Europe's economy, which would not recover until 640, more than a century later. Ice core records show that in 640, there was a spike in atmospheric lead pollution which was the result of an increase in silver mining. Silver is found in lead-rich galena ores. During this time, periods of prosperity almost always coincided with increases in lead emissions. Keep in mind that this is just from recorded history. Imagine all the crazy stuff that happened in prehistory, including population bottlenecks, which reduced the human population to just tens of thousands of people. We could have easily gone extinct on a number of occasions.

@historyinmemes I think WW2 (75 million) and it’s aftermath, particularly in Eastern Europe (Lenin 20 million) and China (45 million), figures in there somewhere. Man made global catastrophes. I image a picnic compared to WW3 though.

The perspective that "bad years" aren't a new phenomenon, but a recurring chapter in human history, is both chilling and eye-opening. The past has seen years of widespread disease, cataclysmic climate events, and massive societal upheavals that make the difficulties of 2020 seem, if not minor, then part of a larger tapestry of human struggle. For instance, 536 AD was a year when nature seemed almost hostile to human life. The volcanic eruptions and the consequent "nuclear winters" were catastrophes on a scale that's hard to imagine, leading to a chain of events that dramatically altered civilizations around the world. The Plague of Justinian was another blow that sapped the vitality of the Byzantine Empire, further cementing the year's reputation as one of the worst times to be alive. What's remarkable is the human ability to bounce back, even if it takes decades or centuries. The spike in lead pollution in 640 AD, indicative of resumed economic activity through silver mining, serves as a telling reminder that humanity has a tendency to recover and advance, no matter the adversities. The events of prehistoric times, including near-extinctions, further underline the resilience of the human race. Our ancestors faced and overcame challenges that we can hardly fathom, and their success is a testament to human adaptability and the indomitable spirit to survive against all odds.

Time Capsule Tales @timecaptales

1816 was another historically catastrophic year. It’s known as the “Year Without a Summer” due to the eruption of Mount Tambora in Indonesia, one of the most powerful volcanic eruptions in history. The eruption spewed enormous amounts of volcanic ash and sulfur dioxide into the atmosphere, which led to a drop in global temperatures. Europe, North America, and Asia experienced extreme weather anomalies, including summer snowfalls, frosts, and unseasonably cold temperatures. This led to widespread crop failures and food shortages, which in turn caused famine and increased mortality.

The year 536 AD stands out as one of the grimmest in recorded history. A volcanic eruption in Iceland dimmed the sun for 18 months, plunging temperatures and leading to widespread crop failures and famine. This decade-long cold spell was exacerbated by another eruption in 540 in El Salvador. By 541, the Plague of Justinian struck, wiping out a huge portion of the Mediterranean population and weakening the Byzantine Empire. These cascading calamities crippled Europe's economy for over a century.
