High-resolution multiproxy analysis from four sites show freshwater wetlands transitioned to mangrove environments 4-3.6 ka, followed by estuarine environments 3.4-2.8 ka, during a period of enhanced climate variability. We calculate a RSLR rate of 0.67 +/- 0.1 mm yr-1 between ~4.2-2.8 ka, 4-6 times lower than current rates. Despite low RSLR rates, the rapid mangrove to estuarine transgression was facilitated by a period of prolonged droughts and frequent storms. These findings suggest that with higher and accelerating RSLR today, enhanced climate variability could further hasten the loss of mangrove-lined coastlines, compounded by the reductions in natural flow to the coast caused by water management. Climate variability is nonlinear, and when superimposed on increases in RSLR, can complicate estimated trajectories of coastal inundation for resource management and urban planning. #------------------ # Funding_Agency # Funding_Agency_Name: United States Geological Survey # Grant: Greater Everglades Priority Ecosystems Science (GEPES), Climate and Land Use Research and Development #------------------ # Site_Information # Site_Name: Florida Bay Russell RUSP3A # Location: North America>United States Of America>Florida # Country: United States Of America # Northernmost_Latitude: 25.07536 # Southernmost_Latitude: 25.07536 # Easternmost_Longitude: -80.64616 # Westernmost_Longitude: -80.64616 # Elevation: -0.231 m #------------------ # Data_Collection # Collection_Name: Jones2019RUSP3A-iso # Earliest_Year: 4200 # Most_Recent_Year: -64 # Time_Unit: Cal.
