Study: Louisiana will lose its existing coast

Planetizen - A study published in Science Advances ... makes a dire prediction for the Louisiana coast: "[T]he remaining 5,800 square miles of Louisiana's coastal wetlands in the Mississippi River delta will disappear." The only question is when.  According to the authors of the study, the wetlands that run along the coast of Louisiana have already reached a tipping point, as sea-level rise trends consistent around the world supplement the local conditions created by the Mississippi River meeting the Gulf of Mexico.
