Coastal ecosystems are a net greenhouse gas sink, new research shows: From mangroves to fjords, coastal ecosystems can take up or emit greenhouse gases. But globally, they're a vital sink
A new greenhouse gas budget shows coastal ecosystems globally are a net greenhouse gas sink for carbon dioxide (CO2) but emissions of methane (CH4) and nitrous oxide (N2O) counteract some of the CO2 uptake, according to researchers.
