re: NOAA says sea levels could rise 2 feet by 2050 in Louisiana.

Abdsolutely correct. I used to be heavily involved in measuring and documenting coastal subsidence and land loss. Had to deal with local and national politicians regularly. There were so many other groups that were sounding alarm bells and showing these wild predictions and the politicians would just eat it up. They wouldnt talk to the actual geologists and engineers like us who were actively quantifying whats going on. The truth is if you live down in the old deltaic lobes of the River that arent getting replenished, yeah you need to be protected, otherwise Louisiana will be fine for many centuries to come.
