The Washington Post reports: Did volcanoes in Russia, Greenland and Alaska affect the lives of ancient Egyptians?
It may sound improbable, but according to a new study, the answer is yes.
In a paper published in Nature Communications, a team of researchers shows that volcanic eruptions in high northern latitudes of the globe can affect the Nile watershed, causing the flow of one of the world’s mightiest rivers to slow.
This, in turn, could keep the lower Nile from flooding in the late summer months — a regular occurrence on which ancient Egyptians relied to irrigate their crops.
No Nile flooding meant no irrigation, which meant a bad year in the fields, low food supplies and, ultimately, civic unrest, researchers say.
