The most populous state in the US is bone dry, and time is running out to save it … must start rationing water now to avoid disaster. … the state is down to its last year of above-ground reserves, and that its groundwater backup is rapidly disappearing. California has no contingency plan for a persistent drought like this one except staying in emergency mode and praying for rain.
With California facing one of the most severe droughts on record, Governor Brown declared a drought State of Emergency
Scientists a decade ago not only predicted the loss of Arctic ice would dry out California, they also precisely predicted the specific, unprecedented change in the jet stream that has in fact caused the unprecedented nature of the California drought.
Causes of California drought are linked to climate change, Stanford University scientists say. The extreme atmospheric conditions associated with California’s crippling drought are far more likely to occur under today’s global warming conditions than in the climate that existed before humans emitted large amounts of greenhouse gases.
How climate change is making California’s epic drought worse
California is undergoing a record-setting drought that began in 2012, the worst in at least 1,200 years. It can be seen in many ways: most of the freshwater reservoirs are drying up, crops are wilting in the fields and groundwater is rapidly depleting. … Climate model simulations show that the extreme and persistent circulation patterns that have caused droughts on the West Coast this century are due to anthropogenic external forces, not natural causes.
