NEW ORLEANS IS SINKING SAID SCIENTISTS


How fast is New Orleans sinking? Faster and faster, says new study
With rising sea levels more coastal communities are coming to terms with the long-term effects of hotter global temperatures.

New Orleans is sinking, according to a study using NASA airborne radar. The subsidence, or sinking rates, of the city and surrounding areas is caused by naturally occurring geologic and human-caused processes. According to this latest study, subsidence is happening at higher rates than what previous data has shown using different kinds of radar, which before had been lower resolution and not as spatially extensive.
Scientists with NASA's Jet Propulsion Laboratory and Louisiana State University used a special kind of radar to measure the ground levels in 2009 and 2012, and  the amount the ground sank during that time. The results in the article published recently in the "Journal of Geophysical Research: Solid Earth" indicate some of the fastest subsidence, or sinking, rates seem to be in areas where groundwater is being pumped.

USA MILITARY BASES AT RISK

Image
Over the past decade alone, thermometers have measured some of the hottest average temperatures in recorded history. As the mercury rises, climate change is quickly becoming an unfortunate reality for many. In the United States alone, 13.1 million people who live in low lying areas could be forced to relocate by rising tides, according to sea level projections. The United Nations’ Intergovernmental Panel on Climate Change predicts sea levels will rise between one and three feet by the end of the century, creating a slew of tangible impacts on industry and residential life. A new report released on Wednesday by the Union of Concerned Scientists brings that reality home to a new group, the military, with predictions that at least 18 military bases are at risk from rising tides. “Reports like this are very helpful,” says Sean Hecht, the co-executive director of the Emmett Institute on Climate Change and the Environment at UCLA School of Law, in a phone interview with The Christian S
