Louisiana Underwater By 2100 — June 28, 2009

A study published in Nature Geoscience concludes the Mississippi Delta, including much of the Louisiana coastline, will be underwater by 2100. According to the research, a combination of rising sea levels and land subsidence will cause all land surfaces below one metre in elevation to be converted to open water or marsh. Researchers Michael D. Blum and Harry H. Roberts conclude that even if sediment loads are restored significant drowning in the Mississippi Delta is inevitable.
