A fixed methane filter maximizes freshwater emissions under warming

Nature Climate Change, Published online: 05 June 2026; doi:10.1038/s41558-026-02649-2How the balance of microbial methane production and oxidation in freshwater systems will change with warming is unclear. This study uses natural warming experiments to demonstrate that methane emissions increase because oxidation keeps pace with, but cannot exceed, warming-accelerated production.
