BP is ending its cleanup of the massive Deepwater Horizon oil spill in three Gulf Coast states this month, leaving Louisiana as the only state with ongoing cleanup linked to the company's Deepwater Horizon Response effort. Reports of oil sightings in Alabama, Mississippi, and Florida will soon be the U.S. Coast Guard's responsibility to investigate.
After interviewing nearly 20 people involved in the coastal restoration process and program — from scientists and engineers, to public officials leading agencies — one of the surprising findings was the consensus among them that people living inside these levees — who live in the most threatened spot in North America due to sea level rise, subsidence and coastal land loss — don’t seem to be fully engaged or aware of just how precarious their situation is.
If there is one underlying justification for Louisiana’s $50 billion Master Plan for coastal restoration, it’s this: We actually have a chance to prevent Southeast Louisiana from drowning in the Gulf, because the Mississippi River carries the sediment necessary to keep pace with sea level rise.
If you stand in front of Almena and Sidney Poray's house in Baton Rouge, La., and look straight down the street, past the other houses and the shade trees, you see more than a dozen plumes of exhaust in various hues of gray and white.
"That's something you see every day, the same thing if not more," says Almena Poray. "Sometimes it's a darker gray; sometimes it's a black smoke coming out."
Let’s imagine it is the Spring of 2025, and Louisiana is preparing to open three diversions on the lower Mississippi so fresh water and sediment can reach wetlands struggling to stay ahead of sea level rise.
It’s almost impossible to find anyone in coastal Louisiana opposed to the idea of “coastal restoration.” Storms like Katrina, Gustav and Isaac have shown everyone the value of the marshes and swamps that once stood between them and the Gulf.
But when “restore” means turning things back to the way they once were, problems can arise.
The best-known example of that is the conflict over using river diversions.
If you’ve been listening and reading along this week, by now you know the consensus among coastal experts is that New Orleans and southeast Louisiana are headed for an early grave before the end of the century.
Because of river levees and damage from oil and gas canals, the wetlands that once protected this city from the Gulf have been reduced by more than half. And now what’s left of this landmass is sinking, at the same time the Gulf is rising due to global warming.
The clang of tide gauges throughout parts of southeast Louisiana aren’t from a science fiction movie, though they may make residents feel like they’re caught in one.
Those sounds tell the stories of rising tides along the Gulf Coast and melting glaciers in the Arctic. And they tell how scientists believe those two events, taking place thousands of miles apart, are the reasons why the Gulf of Mexico is on pace to submerge most of southeast Louisiana by the end of the century — if nothing is done.
