This paper provides a critical evaluation of decadal trends in wetland methane emissions, offering robust insights into how climate change is driving increases in this potent greenhouse gas. By utilizing an ensemble of sixteen models alongside ground-based measurements, the paper provides a robust quantification of emission trends and associated uncertainties. As an international collaboration, this work contributes a comprehensive analysis that not only quantifies recent trends but also identifies temperature as the primary driver, offering essential information for predicting and managing future methane feedbacks.

Short summary
This study assesses global methane emissions from wetlands between 2000 and 2020 using multiple models. We found that wetland emissions increased by 6–7 Tg CH4 yr-1 in the 2010s compared to the 2000s. Rising temperatures primarily drove this increase, while changes in precipitation and CO2 levels also played roles. Our findings highlight the importance of wetlands in the global methane budget and the need for continuous monitoring to understand their impact on climate change.
