"Wetlands have flourished along the world’s coastlines for thousands of years,
playing valuable roles in the lives of people and wildlife. They protect the
land from storm surge, stop seawater from contaminating drinking water
supplies, and create habitat for birds, fish and threatened species.
Much of that may be gone in a matter of decades.
As the planet warms, sea level rises at an ever-faster rate. Wetlands have
generally kept pace by building upward and creeping inland a few meters per
year. But raised roadbeds, cities, farms and increasing land elevation can
leave wetlands with nowhere to go. Sea-level rise projections for midcentury
suggest the waterline will be shifting 15 to 100 times faster than wetland
migration has been clocked.
I have been studying coastal geology and wetlands for more than 40 years. The
rates of sea-level rise that we’re seeing now mean portions of today’s coastal
wetland ecosystems will be lost to the ocean in the years and decades to come
at a tempo never seen before."
