The Antarctic Ozone Hole Will Recover

Since the mid-1990s, global ozone levels have become relatively stable. In fact, because of the Montreal Protocol, model simulations suggest the size of the hole should return to its pre-1980 levels by about 2075. Here, the four globes show monthly-averaged total ozone over Antarctica in October. The 1971 and 2017 globes were created with data from NASA’s Nimbus-4 Backscatter Ultraviolet instrument and Aura’s Ozone Monitoring Instrument, respectively. The 2041 and 2076 globes were made using output from the NASA Goddard Earth Observing System Chemistry-Climate Model, or GEOS-CCM. The graph shows each year’s October average minimum (white dots) over Antarctica. The red curve represents a smoothed version of the white dots.
