Short summary

Methane (CH₄) is a potent greenhouse gas that contributes to global radiative forcing. A mechanistic understanding of how wetland CH₄ cycling will respond to global warming is crucial for improving prognostic models. We present results from the first 4 years of a novel whole-ecosystem warming experiment in a coastal wetland, showing that warming increases CH4 emissions and identifying four potential mechanisms that can be added to future modeling efforts.
