It's the biggest ever, due to cold temperatures. Of course, they say that it would have been bigger without the trillion dollar Montreal thing.
nusa jumped on very weak evidence that a chemical reaction caused the ozone hole. However, it was the heady days of 'blame humans for everything' and they let their imaginations go wild. Next year, the hole will be bigger, and who cares? Are you going suntanning in Antarctica in the winter?
They destroyed the lab experiments and the people, to keep this story going. How embarrassing would that be?
This winter in the Northern Hemisphere, the ozone hole will be bigger than ever, and they will say the same thing, and for next winter, etc. Will the people get suspicious? -- nah.
This is a cute plot. Would they pot the strat temps on top? Nope. Would I do it? Nope. Will anybody do it? Nope.
ps. the comments were cute. They show the nastiness, and why I always misspell things.

“While the 2021 Antarctic ozone hole is larger than average, it is SUBSTANTIALLY smaller than those in the late 1990s and early 2000s.”
I don’t see it! I think that “slightly smaller” would be a better description.
“… without a Montreal Protocol, it would have been much larger,” That sounds like whistling in the dark! How does one prove such a claim?
It looks to me like weather plays a more important role than CFCs. There have been two anomalously low events in 2002 and 2019. Otherwise, there has only been a slight decline in the trend, which could be attributed to temperatures, as the anomalous lows were.

This author is obviously shilling for the CCP. Unregulated aerosol’s use by Chinese industries has undone decades of western bans. Keep trying shill, no one here believes you.

At the risk of sounding shrill, I would like to see the plot of ozone hole size and stratospheric temperatures. It would also be nice to see freon releases, and/or chlorine. Otherwise, I suspect it is just selective plotting to push a story.
