Salt Marshes Face Submergence by 2100, Study Finds.

A 50-year study by the Marine Biological Laboratory (MBL) has found that over 90% of the world's salt marshes are likely to be underwater by the end of the century due to sea level rise. The study, conducted in Great Sippewissett Marsh in Massachusetts, examined the impact of increased nitrogen on marsh grass species and found that even with increased vegetation and accretion of the marsh surface, the ecosystems won't be able to outpace submergence from global sea level rise. The study highlights the importance of understanding the impact of sea level rise on ecosystems and the need to prevent or adapt to losses.
