Study: California Drought Worst in 1200 Years

This is astonishing. I mean, I knew it was bad, I just didn't know it was THIS bad:
As the San Jose Mercury News reported: "The researchers took core samples, which don't harm the living trees, of oaks as old as 500 years and oak logs dating back more than 700 years, the University of Minnesota's Griffin said. And they sanded down the wood with extremely fine-grain sandpaper, magnifying the rings 40 times under a microscope and measuring them to within one one-thousandth of a millimeter." The scientists then used similar data in the North American Drought Atlas to calculate temperature and rainfall conditions.
"Although there are 37 times over the past 1,200 years when there were three-year dry periods in California, no period had as little rainfall and as hot of temperatures as 2012-14, the scientists concluded," the Mercury News reported.
