Ancient Egypt affected by climate change?

Researchers have claimed that ancient Egypt may have been brought down by social unrest caused by climate change and volcanoes. The study, published in Nature Communications, uses modern climate science and ancient texts to explore the impact of volcanic eruptions on the river Nile. It claims that famine and riots were caused by natural events that reduced the summer flooding needed for crop growth.
