Addressing methane emission feedbacks from global wetlands

Earth-system feedback loops that exacerbate climate warming cause concern for both climate accounting and progress towards meeting international climate agreements. Methane emissions from wetlands are on the rise owing to climate change—a large and difficult-to-abate source of greenhouse gas that may be considered indirectly anthropogenic. Here we illustrate the power of emissions reduction from any sector for slowing the progress of earth-system feedbacks. Methane is a powerful greenhouse gas with a large decadal-scale impact on climate change. Accounting for climate and ecological feedback loops can help mitigate its impact.
