TLDR
In this paper, the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances were compared, and it was shown that N 2O emission currently is the single most important ozone-destroying emission and is expected to remain the largest throughout the 21st century.Abstract:
By comparing the ozone depletion potential-weighted anthropogenic emissions of N2O with those of other ozone-depleting substances, we show that N2O emission currently is the single most important ozone-depleting emission and is expected to remain the largest throughout the 21st century. N2O is unregulated by the Montreal Protocol. Limiting future N2O emissions would enhance the recovery of the ozone layer from its depleted state and would also reduce the anthropogenic forcing of the climate system, representing a win-win for both ozone and climate.read more

Carbon and oxygen controls on N2O and N2 production during nitrate reduction
TL;DR: In this article, the authors provide evidence that the form of carbon compound and O2 concentration exert an inter-related regulation on the production and reduction of N2O in soil.

Binding and activation of N2O at transition-metal centers: recent mechanistic insights.
TL;DR: Advances in the understanding of the reaction pathways for N(2)O reduction by metal ions in the gas phase and in heterogeneous, homogeneous, and biological catalytic systems have provided provocative ideas about the structure and properties of metal N( 2)O adducts and derived intermediates, which are likely to inform efforts to design more effective catalysts for N-O remediation.

Large climate-driven changes of oceanic oxygen concentrations during the last deglaciation
TL;DR: The most pronounced deoxygenation episode in the upper ocean occurred midway through the deglaciation, associated with a reinvigoration of North Atlantic Deep Water formation as mentioned in this paper.

Strains in the genus Thauera exhibit remarkably different denitrification regulatory phenotypes
TL;DR: In this paper, the authors defined parameters to describe denitrification regulatory phenotype (DRP) based on accumulation of NO 2, NO and N2O, oxic/anoxic growth and transcription of functional genes.

TL;DR: This study assessed the effects of multiple anthropogenic and natural factors, including nitrogen fertilizer application, atmospheric N deposition, manure N application, land cover change, climate change, and rising atmospheric CO2 concentration on global soil N2 O emissions for the period 1861-2016 using a standard simulation protocol with seven process-based terrestrial biosphere models.
