Summary

This 2022 review examines how disruptions to the nitrogen cycle increase nitrous oxide emissions and contribute to climate change. The authors appear to synthesise evidence on the pathways through which anthropogenic nitrogen inputs and cycling alterations generate N₂O, a potent greenhouse gas with roughly 300 times the radiative forcing of carbon dioxide. The paper likely explores mitigation strategies and the need for integrated nitrogen management to reduce climate impact.

UK applicability

UK agriculture relies substantially on synthetic and organic nitrogen inputs; understanding N₂O emission pathways is directly relevant to UK farm emissions reporting and climate commitments. The findings would inform nitrogen management best practice and regulatory frameworks for reducing agricultural greenhouse gas emissions.

Key measures

Nitrous oxide emission rates; nitrogen cycle alterations; greenhouse gas forcing potential

Outcomes reported

The study examined nitrous oxide (N₂O) emissions resulting from changes in nitrogen cycling processes. The paper addresses the mechanisms by which altered nitrogen cycles contribute to greenhouse gas emissions and climate change.
