Monthly mean atmospheric nitrous oxide (N₂O) concentrations reached a record high of 337.69 parts per million (ppm) in April 2024. This represents an increase of roughly seven percent when compared to April 1990 levels. Globally-averaged annual atmospheric nitrous oxide concentrations reached a new record high in 2023. Nitrous oxide is a potent greenhouse gas with a global warming potential (GWP) 300 times greater than carbon dioxide.
