A new study shows that some of the earliest civilizations in the Middle East and the Fertile Crescent may have been affected by abrupt climate change. These results show that while socio-economic factors were traditionally believed to have shaped ancient human societies in this region, the impact of abrupt climate change should not be underestimated.
A team of international scientists led by researchers from the University of Miami (UM) Rosentstil School of Marine and Atmospheric Science has found that during the first half of the last interglacial period known as the Holocene, which began approximately 12,000 years ago and continues today, the Middle East most likely had wetter climatic conditions than in the past. 6,000 years ago, when conditions were drier and more dusty.
"Evidence of a wet early Holocene has previously been found in the Eastern Mediterranean region, North African and East African lakes, and cave deposits from Southwest Asia, and attributed to higher solar insolation during this period."&"That's right," said Ali Poermand, associate professor of marine geophysical research at the Rosenstill School of Geosciences, who oversaw the project. "Our study, however, is the first of its kind from West Asian locations and is unique in its solution and multi-proxy approach."
The Fertile Crescent, an area in western Asia that stretches from Iran and the Arabian Peninsula to the eastern Mediterranean Sea and northern Egypt, is one of the most climatically dynamic areas in the world, where early human civilizations are believed to have been born.
"The nature and high resolution of this report provided us with a rare opportunity to explore the impact of abrupt climate change on early human societies. We see that the transitions of several major civilizations through this area, as evidenced by the available historical and archaeological reports, coincided with episodes of high atmospheric dust; higher dust flows are attributed to the drier conditions of this area over the past 5,000 years," said Arashsharifi, PhD, in the Department of Marine Geophysical Research and the lead author of the study.
The researchers analyzed climate variability and changes in the paleoconditions of the environment over the past 13,000 years, based on the high resolution of the equipment, which occurs every ten years of the century, as shown by a report analyzing peat taken from Lake Neor in Northwestern Iran. Dramatic climate changes occur between one and ten.
