The new normal - California drought
Some sobering news from the
San Jose Mercury News:
California drought: Past dry periods have lasted more than 200 years, scientists say
California's current drought is being billed as the driest period in the state's recorded rainfall history. But scientists who study the West's long-term climate patterns say the state has been parched for much longer stretches before that 163-year historical period began.
And they worry that the "megadroughts" typical of California's earlier history could come again.
Through studies of tree rings, sediment and other natural evidence, researchers have documented multiple droughts in California that lasted 10 or 20 years in a row during the past 1,000 years -- compared to the mere three-year duration of the current dry spell. The two most severe megadroughts make the Dust Bowl of the 1930s look tame: a 240-year-long drought that started in 850 and, 50 years after the conclusion of that one, another that stretched at least 180 years.
"We continue to run California as if the longest drought we are ever going to encounter is about seven years," said Scott Stine, a professor of geography and environmental studies at Cal State East Bay. "We're living in a dream world."
Going to be rough on farmers. The problem lies in the Pacific Ocean with the stalled
Pacific Decadal Oscillation. No El Ni�o, no La Ni�a, this year has been
La Nada.

Report: Some Bay Area Communities Could Run Out Of Water Within 4 Months
As the drought in California continues, 17 communities throughout the state could run out of water within 60 to 120 days, state officials said.
In some districts, the wells are running dry while other reservoirs are nearly empty. The state Health Department compiled a list after surveying the more than 3,000 water agencies in California last week.
The water systems are in all in rural areas that serve from 39 to 11,000 residents. They range from tiny Lompico County Water District in Santa Cruz County to districts that serve the cities of Healdsburg and Cloverdale in Sonoma County.
