Global natural wetland methane emissions (2000-2025) M. Li et al. https://doi.org/10.5281/zenodo.18870108
Editorial statement
This article describes a new methodology to evaluate CH4 emissions from wetlands on a global scale, providing a scalable capacity to frequently update global emission estimates, such as those presented in the Global Carbon Budget.

Short summary
We proposed a framework that combines machine-learning and climate data to predict global natural vegetated wetland methane emissions for 2000–2025. We found that although total global emissions remained stable in the post-2020s, Northern Hemisphere emissions surged whilst tropical emissions fell. This approach allows us to rapidly monitor emissions and provides early warnings for climate impacts.
