The Florida Everglades is a complicated climate actor. The 1.5-million-acre wetland system remains a carbon sink, removing an average of 13.7 million metric tons of carbon dioxide from the atmosphere each year, but the system also releases methane. In a new study, Yale School of the Environment scientists have analyzed the greenhouse gas fluxes in its mangroves and fresh-water marshes, providing a more detailed approach for guiding restoration efforts.
