When we talk about greenhouse gases and climate change, carbon dioxide (CO2) and methane (CH4) usually receive most of the attention. Yet another gas, nitrous oxide (N2O), quietly plays an important role in our changing climate. Commonly known as "laughing gas", N2O is a powerful greenhouse gas with nearly 273 times the warming potential of CO2 over a 100-year period. Once released, it can remain in the atmosphere for more than a century. During this time, it contributes not only to global warming but also to the depletion of stratospheric Ozone. Its atmospheric concentration has been increasing, largely due to human activities, with nitrogen-based fertilizers used in agriculture being an important contributor.
