10th century–14th century: Megadrought
According to a report from the Proceedings of the National Academy of Sciences of the United States of America, the year 900 launched the start of a dry spell so significant that scientists refer to it as the "Megadrought." The event, which choked the Sierra Nevada and northwestern Great Basin, lasted centuries until tapering off around 1300. A variety of data back up this claim, but tree-ring studies provide the best and most accurate timeline of the catastrophe.
14th century–19th century: Mississippi River Valley drought
Massive earthen mounds still stand where the city-states of the Mississippian American Indian culture once thrived in the Mississippi River Valley 1,000 years ago. Unfortunately for the corn-based society, according to NPR, a "profound drought" set in around 1350, triggering the Little Ice Age in Europe and setting off an intense dry spell triggered by dry Arctic air pouring in through the Gulf of Mexico. The catastrophic drought would last as long as 500 years, much longer than the culture whose crucial corn crops were obliterated by the changing climate.
