Breitbart - is week's statewide rains have made little impact in relieving California's extreme drought. In fact, according to a new scientific study, this drought is the worst that California has experienced in 1200 years. Researchers studying tree rings concluded that "the current event is the most severe drought in the last 1200 years, with single year and accumulated moisture deficits worse than any previous continuous span of dry years."

Causes of Calif. drought natural, not man-made: NOAA
The study notes that this ridge — which has resulted in decreased rain and snowfall since 2011 — is almost opposite to what computer models predict would result from human-caused climate change.
