Marshes Using CO2 to Cope with Global Warming
Carbon Dioxide Stimulates Marsh Elevation Gain, Helping Offset Flooding from Sea Level-Rise ? Elevated concentrations of carbon dioxide may help some coastal marshes keep up with rising sea level by stimulating plant production and marsh building. ?? Coastal wetlands provide barriers to storm surges and flooding, provide valuable habitat for wildlife, and are important nursery grounds supporting commercial fisheries.? The U.S. Geological Survey conducted research that showed how marsh elevations might increase when exposed to higher concentrations of carbon dioxide.? “Coastal wetlands are threatened by sea-level rise, and this research allows for more accurate models to predict how much coastal submergence may occur,” said USGS scientist Karen McKee.
