Coastal Louisiana has lost an average of 34 square miles of land, primarily marsh, per year for the last 50 years. From 1932 to 2000, coastal Louisiana lost 1,900 square miles of land, roughly an area the size of the state of Delaware. If nothing more is done to stop this land loss, Louisiana could […]
ScienceDaily (Sep. 21, 2009) — A new study led by the University of Colorado at Boulder indicates most of the world’s low-lying river deltas are sinking from human activity, making them increasingly vulnerable to flooding from rivers and ocean storms and putting tens of millions of people at risk. While the 2007 Intergovernmental Panel […]
By Sylvia Poggioli The construction of mobile floodgates aims to safeguard the 1,300-year-old island city of Venice. It’s an ambitious engineering project, but some scientists say it may not be sufficient to protect Venice from rising sea levels due to climate change. Venice rose from mudflats in the middle of a lagoon which forms the […]
The islands have been generally shrinking and migrating landward since the late 1800s. A survey in the 1980s estimated that they would be in existence for about three more centuries. Before 1996, the seaward front of the islands lost about 20-30 feet of land each year, mostly replaced at the rear. From 1996 to 2004, […]
By Kim Chipman Sept. 18 (Bloomberg) — Carlton Dufrechou can fly 10 minutes from New Orleans and be over the open waters of the Mississippi Sound. Two decades earlier, before erosion took its toll, he would have looked down on lush wetlands. The destruction accelerated four years ago last month, when Hurricane Katrina struck. The […]
By CHARLES J. HANLEY, Associated Press TUKTOYAKTUK, Northwest Territories — Caught between rising seas and land melting beneath their mukluk-shod feet, the villagers of Tuktoyaktuk are doing what anyone would do on this windy Arctic coastline. They’re building windmills. That’s wind-power turbines, to be exact — a token first try at “getting rid of this […]
The Nile Delta is under threat from rising sea levels. Without the food it produces, Egypt faces catastrophe By Jack Shenker …Today, however, Nile water barely reaches this corner of the Delta. Population growth has sapped its energy upstream, and what “freshwater” does make it downriver is increasingly awash with toxins and other impurities. Farmers […]
As Wetlands Shrink, Oil and Gas Jobs Replace Farming, Fishing and Trapping By Kari Lydersen, Washington Post Staff Writer GOLDEN MEADOW, La. “Every morning is like Christmas morning” during shrimping season, says Whitney Dardar, 73, a Houma Indian who loves fishing in the bayous of southwestern Louisiana as his forebears have done for two centuries. […]
By Mark Schleifstein Even under best-case scenarios of building massive engineering projects to restore Louisiana’s dying coastline, the Mississippi River cannot possibly feed enough sediment into the marshes to prevent ongoing catastrophic land loss, two Louisiana State University geologists conclude in a scientific paper being published today. The result: The state will lose another […]
