Propaganda, Louisiana coastal loss is not a result of climate change. How can they be taken serious when they are misleading as to the causation of the problem here in Louisiana.

Remember the reason why the Mississippi River snakes it way to the ocean where it does is because the area of the delta is sinking into the ocean basin and provides the best/easiest path to the sea. And artificial levees along the river keep little sediment from flowing into the adjoining marsh. You should know and probably do know the Mississippi River has a history of changing course, sometimes a lot on a several thousand year time frame. All those Breton Sound and Chandelier Islands are reworked deltas that in time shifted to other positions. The current track of the Mississippi is a very human influenced at this point. But make no mistake, the area of the delta is sinking continuously if not gradually. I'll leave my coastal geology lesson at this.
