Rain over California’s Owen’s Valley in early May 2016. The 2015–2016 El Niño, which officially ended in late May, was one of the strongest El Niños on record. Although predicted to bring heavy rainfall to California, new research shows El Niño’s rains were not enough to ease California’s ongoing drought. Credit: Dustin Blakey, CC BY-NC 2.0

New research shows that California’s Sierra Nevada snowpack will likely not recover from the current drought until 2019

By Lauren Lipuma, Contributing Writer, EOS The unprecedented drought that has gripped the Southwest United States has severely depleted the Sierra Nevada snowpack, the major source of water for drinking and farming in California.

Weather systems that typically bring moisture to the southwestern United States are forming less often, resulting in a drier climate across the region. This map depicts the portion of overall changes in precipitation across the United States that can be attributed to these changes in weather system frequency. The gray dots represent areas where the results are statistically significant. Map courtesy of Andreas Prein, NCAR.

@NCAR claims: U.S. Southwest sliding into a drier climate, and it’s all your fault

Weather patterns that bring moisture are becoming less frequent From the NATIONAL CENTER FOR ATMOSPHERIC RESEARCH/UNIVERSITY CORPORATION FOR ATMOSPHERIC RESEARCH and the “there’s no natural variation component anymore” department comes this blame game claim that seems to ignore history, like the fact that tree rings show decade and century long droughts in the past: BOULDER…

California’s governor Brown should read this paper about drought – maybe it will get his mind off the bullet train to nowhere and onto reservoirs

Severe drought no longer caused just by nature UNIVERSITY OF BIRMINGHAM Scientists at the University of Birmingham are calling on drought researchers and managers around the world to consider both human activity and natural phenomena in their battle to preserve increasingly scarce global water supplies. The experts say that severe droughts experienced recently in countries…
