A 200-year-long drought 4,200 years ago may have killed off the ancient Sumerian language, one geologist says.Because no written accounts explicitly mention drought as the reason for the Sumerian demise, the conclusions rely on indirect clues. But several pieces of archaeological and geological evidence tie the gradual decline of the Sumerian civilization to a drought."This was not a single summer or winter, this was 200 to 300 years of drought," said Matt Konfirst, a geologist at the Byrd Polar Research Center.Around the same time, 74 percent of the ancient Mesopotamian settlements were abandoned, according to a 2006 study of an archaeological site called Tell Leilan in Syria. The populated area also shrank by 93 percent, he said."People still live in this region. It's not that the collapse of a civilization means that an area is completely abandoned," he said. "But that there's a sharp change in the population."During the great drought, two waves of marauding nomads descended upon the region, sacking the capital city of Ur. After around 2000 B.C., ancient Sumerian gradually died off as a spoken language in the region. For the next 2,000 years, the tongue lingered on as a dead written language, similar to Latin in the Middle Ages, but has been completely extinct since then, Konfirst said.3 thoughts1)Wow climate change when there insignificant number of humans & no gasoline engines or utility or industrial plants.2)We could be going thru a climate change. Just not influenced by human activity.3)Even if climate change is occurring; there may be nothing we can do about it.
