Destruction of coastal habitats may release as much as one billion tons of carbon into the atmosphere each year, ten times higher than previously reported, according to a new Duke led study.
Published online this week in PLOS ONE, the analysis provides the most comprehensive estimate of global carbon emissions from the loss of these coastal habitats to date: 0.15 to 1.2 billion tons.
It suggests there is a high value associated with keeping these coastal-marine ecosystems intact as the release of their stored carbon costs roughly $6-$42 billion annually.
