Changes in stratospheric circulation and temperature, which are driven by climate change, are decreasing the lifetime of nitrous oxide (N2O), which provides negative feedback to atmospheric warming, but adds uncertainty to climate predictions.

Global warming is speeding breakdown of major greenhouse gas, research shows
Scientists at the University of California, Irvine have discovered that climate change is causing nitrous oxide, a potent greenhouse gas and ozone-depleting substance, to break down in the atmosphere more quickly than previously thought, introducing significant uncertainty into climate projections for the rest of the 21st century.
