Short summary

The Australian 2019–2020 wildfires injected a substantial amount of smoke into the upper atmosphere, causing unusual chemical reactions that altered the chemical makeup of the upper atmosphere. This led to ozone depletion in the Southern Hemisphere midlatitudes that likely did not fully recover until 2 years after the initial event due to the persistent chemical effects of the smoke.
