Louisiana Wetlands Struggling with Sea-Level Rise 4 Times the Global Average

Without major efforts to rebuild Louisiana's wetlands, particularly in the westernmost part of the state, there is little chance that the coast will be able to withstand the accelerating rate of sea-level rise, a new Tulane University study concludes.

The study by researchers in Tulane's Department of Earth and Environmental Sciences and published in the open-access journal Nature Communications shows that the rate of sea-level rise in the region over the past six to 10 years amounts to half an inch per year on average.

"In the Mississippi Delta, about 65 percent of study sites are probably still keeping pace, but in the westernmost part of coastal Louisiana, more than 60 percent of sites are on track to drown," said Tulane geology professor Torbjörn E. Törnqvist, a co-author of the study.
