Walter, there have been extensive articles published, now for several years, about the persistent drought in California as well as that projections for California climate w/AGW factored in leading to exactly such a phenomenon. Just because the one particular article linked doesn’t discuss this is hardly a reason to diss Gus because he made the connection.

My connection was that the AGW genuflectors will read it as another part of “the diabolical plan.”

PASADENA, Calif. – New space observations reveal that since October 2003, the aquifers for California’s primary agricultural region — the Central Valley — and its major mountain water source — the Sierra Nevadas — have lost nearly enough water combined to fill Lake Mead, America’s largest reservoir. The findings, based on data from the NASA/German Aerospace Center Gravity Recovery and Climate Experiment (Grace), reflect California’s extended drought and increased rates of groundwater being pumped for human uses, such as irrigation.

“Grace data reveal groundwater in these basins is being pumped for irrigation at rates that are not sustainable if current trends continue,” Famiglietti said. “This is leading to declining water tables, water shortages, decreasing crop sizes and continued land subsidence. The findings have major implications for the U.S. economy, as California’s Central Valley is home to one sixth of all U.S. irrigated land, and the state leads the nation in agricultural production and exports.”

“By providing data on large-scale groundwater depletion rates, Grace can help California water managers make informed decisions about allocating water resources,” said Grace Project Scientist Michael Watkins of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., which manages the mission for NASA’s Science Mission Directorate, Washington.

NASA is working with the National Oceanic and Atmospheric Administration and the University of Nebraska-Lincoln to incorporate Grace data into NOAA’s U.S. and North American Drought Monitors, premier tools used to minimize drought impacts. The tools rely heavily on precipitation observations, but are limited by inadequate large-scale observations of soil moisture and groundwater levels. “Grace is the only satellite system that provides information on these deeper stores of water that are key indicators of long-term drought…”
