California just had its worst drought in over 1200 years, as temperatures and risks rise

Guardian: A new paper published in the journal Geophysical Research Letters by Griffin & Anchukaitis concludes that the 20122014 drought in California was its most intense in at least 1,200 years. The study used drought reconstructions from tree-ring cores, from the North American Drought Atlas (NADA) and from cores Griffin & Anchukaitis collected from blue oak trees in southern and central California. Blue oak tree ring widths are particularly sensitive to moisture changes. According to Griffin, The...

Drought dries rural Calif wells residents carry water in buckets

Sentinel: The water vanished from Olivia Vargas modest East Porterville home on an ordinary morning as she was rinsing her breakfast dishes. It left Yolanda Serratos house just as suddenly, sputtering, then stopping, as she held a garden hose. Soon, the faucets at Iglesia Emmanuel went dry as parishioners tried to clean up after Sunday services. Ten miles away, Ron and Cheryl Perine poured two glasses of water to drink and watched in disbelief as sand settled to the bottom. It was devastating,...

NOAA report says California drought mostly due to natural causes, not global warming
2014-12-08 07:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: The build-up of heat-trapping gases in the atmosphere may worsen western droughts in the future, but it is not the principal driver of historic drought afflicting the entire state of California right now, says a major NOAA report released today. Natural oceanic and atmospheric patterns are to blame for the drought, the 42-page report says. Specifically, it highlights a persistent area of high pressure off the West Coast that has blocked rain-bearing storms from coming ashore which some have...

California's drought may be worst in a millennium
2014-12-07 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: When Daniel Griffin first heard media reports earlier in the fall that California's drought was the worst in the past few centuries, he didn't quite buy it. Griffin, an assistant professor in the Department of Geography, Environment and Society at the University of Minnesota, had a decade of experience studying paleoclimate and environmental science using tree-ring data. From his research on blue oak trees, he knew that periods without a lot of precipitation weren't that uncommon in the state's...

California drought, high temperatures create worst conditions in 1,200 years: study
2014-12-05 22:17:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: A combination of record high temperatures and sparse rainfall during California's three-year drought have produced the worst conditions in 1,200 years, according to a study accepted for publication by the American Geophysical Union (AGU). The state has gone through numerous periods of dry weather, with as little or less rainfall as the past few years, but scientists looking at the cumulative effects of temperature, low precipitation and other factors said that it all adds up to the worst conditions...
