Will the "greenest" State please step forward
Very good article among many on the topic Rick. Potable water is in my opinion the #1 issue of survival, also water for agriculture.
Here is an fairly good video about various programs around the State of Texas and how they are dealing with water shortages.

"The city of Wichita Falls, Texas, may soon become the first in the country where half of the drinking water comes directly from wastewater."

So perhaps Texas are "greener" than Californians or make that "browner", LOL. Well they filtered the brown out, so we assume. ha ha ha
Now I challenge y'all from the "left coast" to post links of how your states and cities are meeting the challenge.
ocean-atmosphere oscillations, 80% change of mega drought, perhaps?
Personally I take issue with a few points when journalist take complex issues and attempt to overly simplify them for example: "there is an 80 percent chance that such an extended drought will strike between 2050 and 2099, unless world governments act aggressively to mitigate impacts from climate change"
Also talking excessively about El Niņo/La Niņa these Southern Oscillation (ENSO) that can affect weather patterns around the globe, but 10 other naturally occurring ocean-atmosphere oscillations in the Pacific, Atlantic, and Indian Oceans have been recognized and named including the North Atlantic Oscillation, Indian Ocean Dipole. These have a lot of influence on our climate in N.A.

So yes it is impossible to be exact on predictions but a general estimate is reasonable. Sorta like saying interest rates generally go up when the markets are down, but exactly how much or on what date … heck if I know.
Soil samples, ice core samples, tree rings, etc all seem to agree this is cyclical how much does/has human or dinosaur behavior add to it, or astroids from outer space, well that is part speculation, part science and a lot of estimation. But mega-droughts have happened and almost certainly will happen again. Exactly when and were is a bit like predicting interest rates or the stock market. If you could do that with 100% accuracy you would be a trillionaire. Good luck with that.
