There has been considerable debate on the contribution of rivers to the global carbon cycle, particularly regarding how climate change alters riverine carbon processing and greenhouse gas (GHG) emissions. Rivers are increasingly recognized as active components of the global carbon cycle1, yet river ecosystem deterioration and its reciprocal interactions with climate change remain insufficiently represented in Earth system and climate assessments. Rivers actively regulate GHG emissions, carbon and nutrient cycling, and ecosystem resilience through interconnected hydrological and biogeochemical processes. However, current climate assessment and mitigation frameworks, including IPCC assessments, national GHG inventories, and UNFCCC reporting, typically evaluate rivers through water resource potential, carbon fluxes, pollution profiles, and GHG emissions independently rather than as interacting components of climate feedback processes. Consequently, they may underestimate how climate change and anthropogenic disturbances collectively degrade river functioning and, in turn, influence regional and global carbon budgets. Further, the impacts of climate change can be more severe in ecosystems whose hydrological and ecological attributes have already been modified by human activities. This is because anthropogenic perturbations have already altered riverine carbon, oxygen and water cycles across the land-ocean aquatic continuum2,3,4. These disturbances alter not only the magnitude of climate responses but also the underlying ecohydrological...
