Scientists reveal a hidden, sunlight-driven source of a potent greenhouse gas

The term greenhouse gas often brings carbon dioxide (CO2) to mind, and rightly so, as it is a key contributor to rising global temperatures. However, a more potent pollutant and greenhouse gas that often gets overlooked is nitrous oxide (N2O). Molecule for molecule, N2O is 300 times stronger than CO2 and is accumulating in the atmosphere faster than expected.
