Unwelcome Dominance Stratospheric ozone is depleted by many different chemicals; most prominently, chlorofluorocarbons (CFCs) responsible for causing the Antarctic ozone hole. Nitrous oxide is also an ozone-depleting substance that has natural sources in addition to anthropogenic ones. Moreover, unlike CFCs, its use and emission are not regulated by the Montreal Protocol, which has helped to reverse the rate of growth of the ozone hole. Surprisingly, Ravishankara et al. (p. 123, published… 

The changing ozone depletion potential of N2O in a future climate

Nitrous oxide (N2O), which decomposes in the stratosphere to form nitrogen oxides (NOx), is currently the dominant anthropogenic ozone‐depleting substance emitted. Ozone depletion potentials (ODPs)

Stratospheric ozone depletion due to nitrous oxide: influences of other gases

Reductions in anthropogenic N2O emissions provide a larger opportunity for reduction in future O3 depletion than any of the remaining uncontrolled halocarbon emissions.

Nitrous Oxide: No Laughing Matter

The report by Ravishankara et al. on page 123 of this issue (1) not only adds to the scientific understanding of this important gas, but is a strong reminder that nitrous oxide deserves much more attention and consideration for policy action to control future human-related emissions.

The effectiveness of N2O in depleting stratospheric ozone

Recently, it was shown that of the ozone‐depleting substances currently emitted, N2O emissions (the primary source of stratospheric NOx) dominate, and are likely to do so throughout the 21st century.

The impact of the rise in atmospheric nitrous oxide on stratospheric ozone

It is known that atmospheric N2O, which is present in the atmosphere in 2020 at a mixing ratio of 332.8 ppb, is not only important for stratospheric ozone but also constitutes the third most important long-lived greenhouse gas (after CO2 and CH4).

Climate change reduces warming potential of nitrous oxide by an enhanced Brewer‐Dobson circulation

The Brewer‐Dobson circulation (BDC), which is an important driver of the stratosphere‐troposphere exchange, is expected to accelerate with climate change. One particular consequence of this

Massive nitrous oxide emissions from the tropical South Pacific Ocean

Nitrous oxide is a potent greenhouse gas and a key compound in stratospheric ozone depletion. In the ocean, nitrous oxide is produced at intermediate depths through nitrification and denitrification,

tropospheric nitrous oxide during ATom

Nitrous oxide (N2O) is both a greenhouse gas in the troposphere and an ozone depleting substance in the stratosphere and is rapidly increasing in the atmosphere. The spatial distribution of N2O

Abiotic mechanism for the formation of atmospheric nitrous oxide from ammonium nitrate.

The formation of atmospheric nitrous oxide from the decomposition of ammonium nitrate via an abiotic mechanism that is favorable in the presence of light, relative humidity and a surface is reported.

Emissions of methane and nitrous oxide from full-scale municipal wastewater treatment plants

Since 1750, the year that commonly marks the start of the Industrial Revolution, the atmospheric concentrations of carbon dioxide, methane and nitrous oxide have risen about 40 %, 150 % and 20 %,
