The atmospheric lifetime of nitrous oxide (N₂O) is approximately 121 years. This measurement reflects the time it takes for nitrous oxide to be removed from the atmosphere through processes like photolysis in the stratosphere or chemical reactions. Understanding the atmospheric lifetime of greenhouse gases is crucial for assessing their long-term impacts on climate change and for formulating strategies to mitigate their emissions. Nitrous oxide, while present in smaller quantities compared to carbon dioxide, has a much greater global warming potential per molecule over a 100-year period. Thus, the 121-year lifetime is significant as it indicates how long this potent greenhouse gas can affect the climate once released into the atmosphere.
