Significance Eutrophication threatens water resources across the globe. Earlier studies showed that climate-induced changes in precipitation would further exacerbate impacts, but observational records were not sufficiently long to conclusively pinpoint the role of future warming. Here, we use a long-term record of riverine nitrogen runoff to show that future warming will likely offset or even reverse the impact of precipitation changes, leading to a possible reduction in nitrogen runoff in the continental United States. Interestingly, future changes projected here are contrary to recent decades, when the impact of precipitation outweighed that of rising temperatures. Quantifying the impact of changes in climate on water quality outcomes at regional to continental scales is critical to ensuring water sustainability now and in the future.
