Groundwater from aquifers important factor in food security
2015-07-08 19:03:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Thirsty cities, fields and livestock drink deeply from aquifers, natural sources of groundwater. But a study of three of the most-tapped aquifers in the United States shows that overdrawing from these resources could lead to difficult choices affecting not only domestic food security but also international markets. University of Illinois professors of civil and environmental engineering Ximing Cai and Megan Konar, along with graduate student Landon Marston and Lehigh University professor Tara Troy,...

World Aquifers Losing Replenishment Race, Researchers Say
2015-06-26 14:12:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: From the Arabian Peninsula to northern India to Californias Central Valley, nearly a third of the worlds 37 largest aquifers are being drained faster than they are being replenished, according to a recent study led by scientists at the University of California, Irvine. The aquifers are concentrated in food-producing regions that support up to two billion people. A companion study indicates that the total amount of water in the aquifers, and how long it will last at current depletion rates, is...

Safe long-term storage large amounts carbon dioxide in saline aquifers?
2015-05-21 19:03:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: The carbon dioxide (CO2) at the Bravo Dome gas field in New Mexico is volcanic in origin, and its emplacement began more than a million years ago, not 10 thousand years ago, as previously estimated. Averaged across the reservoir, only 20% of the CO2 has dissolved into the field's saline brine over 1.2 million years, while the rest remains as a free gas trapped by the cap-rock, suggesting that safe long-term storage in geological sites is viable. This study documents the first field evidence for...
