While carbon dioxide and methane are the two most common greenhouse gases, nitrous oxide is also a potent contributor to our warming climate. Overuse of fertilizers containing nitrogen in farming has been identified as one of agriculture’s contributions because it can contribute to the addition of nitrous oxide to the atmosphere. Recently scientists at Auburn University and in Australia studied the role of global fertilizer use in affecting the global climate and published the results of their modeling study in Nature Climate Change.
