The Midwest doesn't look so bad right about now...
But, this is a byproduct of rising oceans. SOME people don't believe it, and wonder why it is happening. But the facts are obviously there.

Actually, it's not. South Louisiana is a giant tidal delta. As the Mississippi River and its distributaries like the Bayou Lafouche would flood in the spring, they would deposit sediment. As that sediment piles up, the land "rises". However, that sediment is generally pretty wet when it's deposited, so over time, it's volume goes down as water is squeezed out of it by land deposited on top. As long as there were annual floods, the land kept rising. However, after the Army Corps of Engineers levied off the entire river system, the sediment was completely cut off from replinishing the delta. Instead of new soil being added every year, what was there has slowly dried out and shriveled in volume. Couple that with the natural wave action along the coast that is constantly eroding away land, and the fact that nearly all of the Mississippi River's sediment is now being deposited off the continental shelf, and you have a recipe for subsidence no matter what the ocean does.

I would bow more, but there are limits in place. Great explanation.

Intersting. Thanks for sharing. I learned somethin.
Kind of scary when you think about these people spraying the atmosphere to alter climate change when they can't even understand the impact of changing flood patterns.

Yall all be real careful making any snarky remarks about Louisiana up in here. A great way to visit Banland as the LSU types get sensitive easily.

I think it was her that narrated "Hurricane on the Bayou"
smoked a joint and saw it on iMax. Immediately turned into an atchafalaya activist.

If Louisiana falls into the Gulf then all our seafood will taste like corndogs.

So what you're saying is LSU is literally in decline.

Hahaha, technically, no. LSU is far enough north that it sits on top of the natural levee (i.e. actual land). It's not really sinking much at all. Places that are in much more danger are Loyola, Tulane, UNO, Nicholls, McNeese, ect.

If Louisiana sinks into the gulf, Bama will find room for all their 5* recruits.

Need to get some Dutch ocean engineers in there to help tackle the issues from their experience

They have actually spent a lot of time in new Orleans working with local engineers on this issue.
