and the marsh stops accreting. The shaded region illustrates the most likely range based on 

 current literature: global sea level rise of 50-200 centimeters and accretion of 4-6 millimeters per 

 year. Within this likely range, a negligible loss of wetlands is possible; however, over half the 

 shaded region shows an 80 percent loss of marsh by 2100.

MARSH ACCRETION (Millimeters/Year) 



The shaded area represents the most likely range of sea level rise (50-200 cm, global; 75-225 cm, 

 relative to Charleston) and marsh accretion (4-6 mm/yr). 



'Wetland loss in excess of 80 percent occurs only if today's uplands are protected.
