Feedbacks between climate change and CH₄ emissions from wetlands. (a) CH₄ emissions excluding (solid red line) and including (dashed red line) the effects of climate change on wetland extent and temperature. CO₂ concentrations (blue line) for comparison. (b) Global mean radiative forcing from CH₄ (red lines), CO₂ (blue line) and all species (black line), with effects of climate change on CH₄ emissions excluded (solid lines) and included (dashed lines).
