Coastal Ecosystems Are a Net Greenhouse Gas Sink, New Research Shows

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 international researchers led by Australia’s Southern Cross University.

The new findings of the coastal greenhouse gas balance (CO2 + CH4 + N2O) in ten world regions and globally are outlined in the paper, Coastal vegetation and estuaries collectively are a greenhouse gas sink, published today in Nature Climate Change. From tropical lagoons to polar fjords, from coastal mangrove forests to underwater seagrass communities, many coastlines around the world show high diversity in greenhouse gas sinks and emissions.

“Understanding how and where greenhouse gases are released and absorbed in coastal ecosystems is an important first step for implementing effective climate mitigation strategies,” said lead researcher, Dr Judith Rosentreter, Senior Research Fellow at Southern Cross University.
