Louisiana Coastline Endangered
A new study by geologists Harry Roberts and Michael Blum recently published in Nature Geoscience claims that between 2000 and 2100, the combined effects of sinking land and rising sea-levels will create the loss of as much as 13,500 square kilometers along Louisiana’s coast — about 10 percent of the total area of Louisiana. Gages near the tip of the Mississippi Delta show the land there sinking by as much as 8 mm per year. Combined with rising sea-levels of approximately 3 mm per year, this spells certain problems for Louisiana’s coast. Additionally, if this research is correct, it is likely that restoration efforts in wetlands and barrier islands would be a lost cause because the coastline as a whole is unsustainable.
