Abstract Agricultural soils contribute ~52% of global anthropogenic nitrous oxide (N2O) emissions, predominantly from nitrogen (N) fertilizer use. Global N2O emission factors (EFs), estimated using IPCC Tier 1 methodologies, largely rely on short-term field measurements that ignore legacy effects of historic N fertilization. Here we show, through data synthesis and experiments, that EFs increase over time.

Child Paediatric Lung Disaese Rare lung diseases Thoracic Surgery Bronchoscopy A 12-year-old boy presented with a 1 month history of cough and exertional dyspnoea. Physical examination revealed a heart rate of 106 beats/min, a respiratory rate of 28 breaths/min and an O2 saturation of 90–95%. Bilateral breath sounds were coarse with audible rhonchi. Contrast-enhanced chest CT revealed a large mass in the mediastinum and left lung.

(a) Model performance based on different observations. R2c and R2m are the coefficients of determinations for mixed and fixed effects, respectively. RMSE is root mean square error. Details of additional observations from Cardinael et al. ( 2024 ) can be found in Table S3 . Global variations of the differences in Rfallow (b), its dominant driver (c), and adjusted EF (d) for all cropping systems between the updated and original results from Shang et al. ( 2024 ).
