Projected Precipitation Increases are Bad News for Water Quality

Aug. 1, 2017

Several studies show that changes in precipitation can amplify the effects of nitrogen input on coastal ecosystems. V. Balaji, head of the modeling system group at GFDL and Princeton, is the coauthor of a study published July 28 in Science that examines the implication of future nitrogen loading for the future of these ecosystems, when combined with projections of future precipitation over the next decades. The authors find that future precipitation changes alone will drive large and robust increases in watershed-scale nitrogen fluxes by 2100 following the "business-as-usual" scenario for large portions of the continental United States.
