California drought link greenhouse gases, climate change

San Jose Mercury News: The stubborn high-pressure systems that block California rains are linked to the abundance of human-caused greenhouse gases that heat the oceans, according to a major paper released Monday by Stanford scientists. But two other new studies disagree -- saying there's no evidence that warming ocean waters are to blame for our drought. The dispute comes at the end of the state's official "water year," which closes Tuesday with less than 60 percent of average precipitation. California's major reservoirs...

Reuters: Californias catastrophic drought has most likely been made worse by man-made climate change, according to a report released Monday by Stanford University, but scientists are still hesitant to fully blame the lack of rain on climate change. The research, published in the Bulletin of the American Meteorological Society as part of a collection of reports on extreme weather events in 2013, is one of the most comprehensive studies linking climate change and California's ongoing drought, which has...

The fingerprint of climate change on the California drought, extreme weather in 2013

Washington Post: Researchers studying the fingerprint of human-caused climate change on extreme weather events in 2013 have found that it played a role in half of the events that they looked at, including the California drought and extreme heat events. Climate change attribution figuring out what role climate change is playing in our weather events is a very difficult science. There are so many moving parts: ground-level weather conditions, large-scale atmospheric patterns, and global teleconnections, like...

The drought you can't see

Science: The Western Hemisphere is experiencing a drought of crisis proportions. In Central America, crops are failing, millions are in danger of starvation, and if the drought doesn't break soon, even vessels transiting the Panama Canal will need to lighten their loads, which will increase prices for goods transported globally. In the western United States, the drought-stricken region spans a vast area responsible for much of the nation's fruits, vegetables, and beef. As the drought's grip has tightened,...

LA Times: Under the blistering Central Valley sun, Filiberta Sanchez and her toddler granddaughter strolled down a Parkwood sidewalk lined with yellow weeds, dying grass and trees more fit for kindling than shade. "It was very pretty here, very pretty," said Sanchez, 56, as little Jenny crunched a fistful of parched dirt and pine needles she grabbed from the ground. "Now everything's dry." Parkwood's last well dried up in July. County officials, after much hand-wringing, made a deal with the city of...
