Roughly 90 % of atmospheric ozone is found in the lower strat-osphere in the ozone layer. Since about the 1970s, anthro-pogenic emissions of ozone-depleting gases have led to depletion of ~3–4 % of the total overhead ozone averaged over the globe1. The strongest depletion is found over Antarctica during spring, when photochemical processes combine with a unique set of meteorological conditions to greatly increase the effectiveness of ozone-depleting gases, and more than half of the total over-head ozone is destroyed. Characteristics of the resulting Antarctic ozone hole are reviewed in refs 1 and 2, and the identification and attribution of the phenomenon was recently celebrated in a special edition of Nature
