|a Assumptions of a static landscape inspire predictions
that about half of the world’s coastal wetlands will submerge
during this century in response to sea‐level acceleration. In
contrast, we use simulations from five numerical models to
quantify the conditions under which ecogeomorphic feedbacks
allow coastal wetlands to adapt to projected changes
in sea level. In contrast to previous sea‐level assessments,
we find that non‐linear feedbacks among inundation, plant
growth, organic matter accretion, and sediment deposition,
allow marshes to survive conservative projections of sealevel
rise where suspended sediment concentrations are
greater than ∼20 mg/L. Under scenarios of more rapid
sea‐level rise (e.g., those that include ice sheet melting),
marshes will likely submerge near the end of the 21st century.
Our results emphasize that in areas of rapid geomorphic
change, predicting the response of ecosystems to climate
change requires consideration of the ability of biological processes
tomodify their physical environment. |
