I think the Mega Droughts refer to the catastrophic droughts that the mid-west experiences every few hundred years or so.
There was one in the 13th century that caused the decline of the pueblo peoples and made many parts of the southwest uninhabitable for hundreds of years. There was also one in the 11th century that lasted 50 years. California seems to have them every 100 years or so.
Basically, with or without anthropogenic climate change, the region is fucked.
