This is the talk page for discussing improvements to the Ozone depletion article. This is not a forum for general discussion of the subject of the article.
Ozone depletion was a good articles nominee, but did not meet the good article criteria at the time. There may be suggestions below for improving the article. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake.

"In 2019, NASA reported that there was no significant relation between size of the ozone hole and climate change." This is an inaccurate statement to what NASA said. What NASA said is here: https://www.nasa.gov/centers-and-facilities/goddard/2019-ozone-hole-is-the-smallest-on-record-since-its-discovery/
The reference made is to a Hill article and not NASA itself.
NASA statement says that the ozone natural expands and contracts. And the closure of the ozone hole above the Arctic in 2019 for a weeks was not a sign of substantive corrective climate change but of multiple natural weather phenomenon that temporally combated ozone depletion. NASA was quiet clear man-made depletion has occurred, but gradual corrective measures are being taken: "Atmospheric levels of man-made ozone depleting substances increased up to the year 2000. Since then, they have slowly declined but remain high enough to produce significant ozone loss. The ozone hole over Antarctica is expected to gradually become less severe as chlorofluorocarbons— banned chlorine-containing synthetic compounds that were once frequently used as coolants—continue to decline. Scientists expect the Antarctic ozone to recover back to the 1980 level around 2070." ~2025-32907-87 (talk) 21:54, 11 November 2025 (UTC)Reply
