Louisiana has been losing about 25 square miles of land per year in recent decades”. “If temperatures continue to warm, sea level is likely to rise one to three feet during the next century. Rising sea level has the same effect as sinking land, so changing climate is likely to accelerate coastal erosion and land loss.
