Man could easily alter the climate if we chose. To me.. that's proof

No that not proof. Thats an extrapolation based on your opinion.

Really? How so? Since it is beyond Proof that we can you should be able to provide us 1000s of examples.

Who are you replying to?

What is unique about that area? Water seeks it's own level, so the same should be seen most everywhere. Why isn't it?

South Louisiana is a depositional environment. As the river deposits its sediment load during flood, the land is built up in layers - sedimentary layers. As new layers are formed on the top, there is more weight on the lower layers. These layers start to compact, lowering the land surface above. This is compensated for by adding new sediments.

Once the lad around the river is built up high enough, the water will seek an easier, lower/shorter, path to the sea. That's why we see multiple delta formations all over the coast.

After the river builds up a delta and changes course, there is no more sediment being transported to that area, but the relatively newly formed sedimentary layers continue to compact. The newer the sediment, the faster the compaction.

The current bird's foot delta of the Mississippi represents the newest sedimentary deposits, and as such have the highest potential to compact. The sediment in the river has been largely cut off from the surrounding land, so the land is not replenished as the sediments compact (subside). Therefore subsidence is faster on newer land, and the delta is the newest land on the coast, so we should see the highest compaction/subsidence in the delta.

The delta and the area south of Houma around Lake Boudreaux have the highest subsidence rates in the state.

Subsidence, wind/water, current exposure, etc. all impact.
The point being 4.7" of sea level increase doesn't account for a 60 yr coastal decline illustrated in the gif I posted. However, that graphic came from a site claiming the entire illustrated change is due to sea level increase.

proof of concept. you're intentionally obtuse and the schtick is getting old.
