The current drought in California appears to the worst in the last 1200 years .....

http://onlinelibrary.wiley.com/doi/10.1 ... 3/abstract

Abstract
For the past three years (2012-2014), California has experienced the most severe drought conditions in its last century. But how unusual is this event? Here we use two paleoclimate reconstructions of drought and precipitation for Central and Southern California to place this current event in the context of the last millennium. We demonstrate that while 3-year periods of persistent below-average soil moisture are not uncommon, the current event is the most severe drought in the last 1200 years, with single year (2014) and accumulated moisture deficits worse than any previous continuous span of dry years. Tree-ring chronologies extended through the 2014 growing season reveal that precipitation during the drought has been anomalously low but not outside the range of natural variability. The current California drought is exceptionally severe in the context of at least the last millennium and is driven by reduced though not unprecedented precipitation and record high temperatures.

What is unprecedented is the demand for water in CA because of gross human overpopulation. The farmers and ranchers are left dry in favor of flushing toilets in LA. Just like I foresaw in the book section I wrote ten years ago. It WILL go far beyond historic.
