Old Weather Signs Give Us A New Clarification Of History

Joseph Manning, a professor of history at the University of Yale, fondly remembers the time when he was presented with an archeological paper describing the eruption of some superpowers some 2,500 years ago. While reading the paper, “I really fell in my chair,” he said recentlyand.

Relying on new geochemical methods to detect icebergs to determine dates in volcanic eruptions for a year or a year, paper, published in Nature in 2015, he showed that the largest global eruption caused rain, up to a decade.and global warming. Subsequent research nailed those drops to 13 degrees F.and

What amazed Manning, an Egyptian scholar, was that the paper was repeated 7 to 8 years, so that the days of the eruption coincided with the political, social, and military upheavals of Egypt’s 300-year history. The paper also linked volcanic eruptions with 6 major onesth epidemics of AD AD, famines, and economic crises in Europe, Asia, and Central America. The indisputable fact is that volcanic ash, which cools the earth by shielding it from the sun’s rays, damaging the growing season, and crop failures, helped to alleviate the problem, says the paper.

Since then, other study papers based on paleoclimatic data — many of which use sophisticated technologies designed to understand climate change — have found countless instances where climate change contributed to social and political turmoil and, in many cases, collapsed. . Recent and a paperand published last monthand mu Communications Earth is a universe which resulted in “a steady connection between volcanic eruptions and a powerful collapse of two thousand years of Chinese history.”

The study found that 62 out of 68 dynastic fallsand there was a recent volcanic eruption in the northern hemisphere, the result of which was only one chance out of 2,000 to occur if the eruption and collapse were not coincidental. The Chinese traditionally refer to the abolition of the “heavenly position” to describe the cold, drought, floods, and agricultural failures that seemed to accompany the fall of the dynasty. The paper argues that the event consists of a description of the weather.

Both papers are inspired by the nearly decade-long evolution of climate science. The abundance of information from the “climate” – glaciers, tree rings, stalagmites and stalactites, lakes, bogs, and underwater mud – has contributed to the way historians do their work.

Joe McConnell, who runs the distraction ice core analytical laboratory at the Desert Research Institute in Reno, Nevada, believes that climate information provides historians with evidence that DNA evidence provides a system of judgment: an undeniable, well-known source of vital information. As DNA evidence reverses the erroneous verdict, McConnell said, weather information is the information that historians “must follow.”

To find out more, historians go through many barriers within their studies to work with biologists, geologists, geographers, paleoclimatologists, meteorologists, anthropologists, and others. These mold historians are studying geochemistry and climatology; the scientists he works with are reading history.
