This 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 (2014) and accumulated moisture deficits worse than any previous continuous span of dry years."
The study, published as a research letter in the journal of the American Geophysical Union, was written by Daniel Griffin of the University of Minnesota and Kevin J Anchukaitis of the Woods Hole Oceanographic Institution. By measuring tree rings from nearly 300 blue oaks, and comparing those measurements with data from older trees such as giant sequoias, scientists were able to generate estimates of rainfall for centuries.

Wonder WHO paid the bill for this "study?"
They used what water that was left to put out the big fire in LA.
Where did they find the 1200 year old tree that was used in the study? I smell a rat!
Great for gold seekers. Rivers from hundreds of years are now dry. ....7:30 some things are just obvious. I'm sure you can find a better gripe on any other article.
