Do you remember Isle De Jean Charles....when those people had to leave, the New York Times ensured it was front page news and used the term “CLIMATE REFUGEES IN AMERICA” . THe people were told not to settle in that area in the 50s due to the constant changing of the Mississippi River channeling. Once an area fails to receive the silty annual deposits, it will sink. The boot is changing, and it is not climate change. It is simply mans interaction with the environment and natural alluvial processes.
I grew up in South Louisiana in part of the time frame and in the areaa that the lower Mississippi River control system was being built.
WE agree with the silty deposit cause...but the lack is really due to mans intervention into a natural process, and is fixable (and NOT by blowing up all the levees and letting the full volume of the Mississippi channelize into the Atchafalaya).
