Loss of Louisiana marshes that protect New Orleans is 'probably inevitable,' study finds

ees throughout Louisiana's coastal marshes have died due to a combination of the saltwater intrusion and subsidence.
Rising seas are likely to overwhelm the wetlands that line the coast of Louisiana, destroying the protection they offer the city of New Orleans as well as the fisheries and tourism that contribute heavily to the state’s economy, a new study says.

The imperiled wetlands at the base of the Mississippi River have crossed a critical tipping point, according to the new research, which was published in Science Advances and is based on hundreds of measurements that revealed the fate of ancient marshes in this region.

Researchers found that the type of wetlands that exist in present-day coastal Louisiana have rarely persisted when rates of sea-level rise surpassed 3 millimeters per year over long periods of time. Current sea levels are rising at rates that already slightly exceed that, and those rates are increasing.
