Ancient Bronze Age city reemerges from Iraq river after extreme drought

3. Climate change wiped out a lot of great civilizations

Cities were wiped out by volcanic winters, droughts, rivers that silted up and changed course, earthquakes that changed river patterns, and occasionally something humans caused, like the slow poisoning of the soil that sustained the Sumerians, caused by their success in irrigating it. Warfare certainly didn't help, but it was often an artifact of climate change.

In fact, it has been suggested that the frequent and wide swings in climate in Africa drove human evolution, itself. The argument is persuasive.

As for this city, it pops up every time there is an especially dry year. Unfortunately, that seems to be coming more frequently.
