Topsy-turvy Currents Key to Removing Nitrate from Streams, UCI-led Study Finds

Written on March 15, 2018.

Scientists calculate ‘speed limit’ for pumping pollutant to hungry algae, bacteria Mar. 15, 2018 – More than 500 years ago, Leonardo da Vinci sketched what he called “la turbolenza,” comparing chaotic swirls atop flowing water to curly human hair. It turns out those patterns influence myriad phenomena, from the drag on an airplane’s wings and the formation of Jupiter’s red spot to the rustling of tree leaves. New findings to be published Friday in the journal Science add...

Ocean plankton sponge up nearly twice the carbon currently assumed

Written on March 18, 2013.

Janet Wilson, UC Irvine News Irvine, Calif. – Models of carbon dioxide in the world’s oceans need to be revised, according to new work by UC Irvine and other scientists published online Sunday in Nature Geoscience. Trillions of plankton near the surface of warm waters are far more carbon-rich than has long been thought, they found. Global marine temperature fluctuations could mean that tiny Prochlorococcus and other microbes digest double the carbon previously calculated. Carbon dioxide...

The Coming Water Wars?

Written on February 25, 2013.

Global Public Square Staff, CNN World Imagine a large body of water – about the size of the Dead Sea – simply disappearing. It sounds like a science fiction movie. But it’s not. It’s happening in real life – and we’ve only just found out. A pioneering study from NASA and the University of California Irvine shows how the Middle East is losing its fresh water reserves. As you can see from the satellite imagery in the video, we’re going from blues and greens, to yellows and reds: that’s...

Watering Fields in California Boosts Rainfall in Southwest

Written on January 22, 2013.

Irrigation has downstream effects on climate and runoff to Colorado River Erin Wayman, Science News Farmers in California help make it rain in the American Southwest, a new computer simulation suggests. Water that evaporates from irrigated fields in California’s Central Valley travels to the Four Corners region, where it boosts summer rain and increases runoff to the Colorado River, researchers report online January 12 in Geophysical Research Letters. This climate link may be crucial...

Kenneth Turan, Los Angeles Times “Last Call at the Oasis” is a playful title for a film that couldn’t be more deadly serious. A thorough examination of the epic crises threatening the world’s water supply, crises that few people are paying attention to, this documentary tells you to be afraid, very afraid. Because the water situation is so dire, it has been examined...

When There Really Is Not a Drop to Drink

Written on May 3, 2012.

‘Last Call at the Oasis,’ a Documentary About Water Supplies A. O. Scott, The New York Times Jay Famiglietti, one of a handful of expert witnesses in Jessica Yu’s “Last Call at the Oasis,” is a thoughtful scientist with an engaging manner who specializes in water. In particular, he studies — and tries to raise public awareness about — the rapid depletion of water supplies caused by agricultural overuse, rampant development and global climate change. His analyses are thorough and clear,...

Wastewater Recycling Actually Increases Greenhouse Gas Emissions

Written on September 29, 2011.

ClickGreen Staff, Click Green Wastewater recycling processes may generate more greenhouse gases than traditional water-treatment processes, a new study has found. Despite this finding, the report suggests there are good reasons to continue keep wastewater recycling among the water-resource tools for urban areas. Author Amy Townsend-Small, assistant professor of geology and geography at the University of Cincinnati, and a team of researchers from the University of California,...
