"Don't worry! It'll get worse"
As the economy sinks into a deflationary depression and the West fights a cold war (and a hot war in Ukraine) with Russia, the world is burning and the power-that-be are fiddling.
Don't expect one storm and floods to make any difference to California's woes. The aquifers are being exhausted by the Infinite Growth.

California Needs 11 Trillion Gallons of Water to End Epic Drought
17
December, 2014
California’s
record-setting three-year-old
drought has
left the state with a massive water deficit, and communities,
agricultural interests and others warring
over access to
the supply
Now
groundbreaking new calculations based on Now groundbreaking new
calculations based on NASA
satellite data have
revealed just how large that deficit is. A team of sci’s Jet
Propulsion Laborator (JPL) crunched data from NASA’s Gravity
Recovery and Climate Experiment (GRACE) to figure out how much water
it would take to end the drought. They determined that it would
take 11 trillion gallons—about 1.5 times the maximum volume of the
largest U.S. reservoir—to make up for drought losses due to record
heat and low rainfall.
“Spaceborne
and airborne measurements of Earth’s changing shape, surface height
and gravity field now allow us to measure and analyze key features of
droughts better than ever before, including determining precisely
when they begin and end and what their magnitude is at any moment in
time,” said NASA team leader Jay Famiglietti. “That’s an
incredible advance and something that would be impossible using only
ground-based observations.”

The
NASA team found that the volume of water in the Sacramento and San
Joaquin river basins had decreased by 4 trillion gallons a year since
2011—more water than is used by the state’s residents each year
for domestic and municipal purposes—and that water storage in the
two basins is currently 11 trillion gallons below normal, a deficit
that has steadily increased since GRACE launched in 2002. Depletion
of groundwater in
California’s fertile agricultural Central Valley is responsible for
two-thirds of the loss.
“Integrating
GRACE data with other satellite measurements provides a more holistic
view of the impact of drought on water availability, including on
groundwater resources, which are typically ignored in standard
drought indices,” said Matt Rodell, chief of the Hydrological
Sciences Laboratory at Goddard.

Making
matters worse, data from NASA’s Airborne Snow Observatory earlier
this year showed that California’s Sierra Nevada snowpack was half
that of earlier estimates.
“The
2014 snowpack was one of the three lowest on record and the worst
since 1977, when California’s population was half what it is now,”
said Airborne Snow Observatory principal investigator Tom Painter of
JPL. “Besides resulting in less snow water, the dramatic reduction
in snow extent contributes to warming
our climate by
allowing the ground to absorb more sunlight. This reduces soil
moisture, which makes it harder to get water from the snow into
reservoirs once it does start snowing again.”
The
NASA scientists said that the recent rainstorms in California will do
little to alleviate the water shortage, failing to provide anything
close to the amount of water the state needs to end its prolonged
drought.
“It
takes years to get into a drought of this severity, and it will
likely take many more big storms, and years, to crawl out of it,”
said Famiglietti.
