Future warming and associated permafrost thaw, together with enhanced human perturbations will increase terrestrial N input into surrounding river networks. Warming also raises water temperatures (highlighted in orange), promoting N2O production via denitrification with suppressing the reduction of N2O to N2, eventually resulting in elevated N2O emissions.
