What a weird article. The island isn’t named Tabasco Island, it is endangered of being “swallowed up,” and the threat faced by the surrounding swamps isn’t global warming, but submergence. (It’s not even really an island, but may end up one.)
Yes, but the submergence is due to a lack of soil replenishment due to the channelization of the Mississippi River.
Unfortunately, with the long-term dredging of the existing channel, the delta has extended far enough into the Gulf so that the load of suspended soil is dropped into deep water.
What is needed is to redirect the channel to run west rather than south. It would probably also help if the Bonnet Carre floodway was rebuilt to dump into the Atchafalaya basin instead of Lake Ponchartrain.
But either of those would cost quite a bit.
Yes, it is an island
I guess the 100 years of paving the Mississippi River, thus mitigating seasonal flooding (and the massive transfer of silts and clays into the Mississippi delta) has nothing to do with the gradual submergence of the land masses in the delta?
Nope. It must be climate change.
