Are You Ready for a 35-Year Drought?

The American West has lost an estimated 63 trillion gallons of groundwater over the past 18 months

“A new study estimates that the possibility of a decade-long drought hitting the Southwest sometime this century could be as high as 90 percent. And there’s as much as a 50 percent chance of a ‘megadrought’ that lasts for 35 years or more.”

Take the current drought and double it; that is what a 35 year drought would look like.
