New Orleans Is In Big Trouble

SOURCE: IFLScience.com and NASA. DATE: May 19, 2016 SNIP: NASA has confirmed that New Orleans and the surrounding areas are sinking at a much higher rate than previously thought. … While the fact that the region is sinking is not new, NASA have highlighted that the degree to which it is happening is much greater than previously thought, and that it could be putting certain regions at a much greater risk of flooding, as if there wasn’t a big enough one to begin with. It is hoped that the data can be used to attempt to reduce or reverse the subsidence in the most severely affected areas, as well as help with planning decisions for the...

California Sinking Faster Than Thought, Aquifers Could Permanently Shrink

SOURCE: Yahoo News DATE: August 22, 2015 AUTHOR: Tia Ghose SNIP: California is sinking even faster than scientists had thought, new NASA satellite imagery shows. Some areas of the Golden State are sinking more than 2 inches (5.1 centimeters) per month, the imagery reveals. Though the sinking, called subsidence, has long been a problem in California, the rate is accelerating because the state’s extreme drought is fueling voracious groundwater pumping. “Because of increased pumping, groundwater levels are reaching record lows — up to 100 feet (30 meters) lower than previous records,” Mark Cowin, director of California’s Department of Water Resources, said in a statement. “As extensive groundwater pumping continues, the land is sinking more rapidly, and this puts nearby infrastructure at greater risk of costly damage.” What’s more, this furious groundwater pumping could have long-term consequences. If the land shrinks too much, and for too long, it can permanently lose its ability to store groundwater, the researchers said. MORE:...
