Atmospheric Nitrous Oxide Variations on Centennial Time Scales During the Past Two Millennia
International audience The continuous growth of atmospheric nitrous oxide (N2O) is of concern for its potential role in global warming and future stratospheric ozone destruction. Climate feedbacks that enhance N2O emissions in response to global warming are not well understood, and past records of N...
