Parched California Braces for Drought Without End in Sight

As California and other western states face what some scientists fear could be a prolonged drought amplified by global warming, water experts say there’s simply no way to predict how long the dry spell will last.

The best thing to do, they said, is to prepare for the worst and hope for rain. It wouldn’t be the first time California soil went parched for a long stretch. Tree growth rings in the region show evidence of prolonged periods of aridity in the past.

“To know that we are going into another pattern like that, that we could expect this drought to persist for 10 to 15 years is really, really, really hard to say,” Brian Fuchs, a climatologist with the National Drought Mitigation Center in Lincoln, Neb., told NBC News. “There is really nothing in our forecasting models that are being looked at that would suggest that we would even have the ability to do that.”
