Colder-than-average temperatures in the Antarctic stratosphere created ideal conditions for destroying ozone this year, but declining levels of ozone-depleting chemicals prevented the hole from as being as large as it would have been 20 years ago.
The 2018 ozone hole was strongly influenced by a stable and cold Antarctic vortex—the stratospheric low pressure system that flows clockwise in the atmosphere above Antarctica. These colder conditions—among the coldest since 1979—helped support formation of more polar stratospheric clouds, whose cloud particles activate ozone-destroying forms of chlorine and bromine compounds.

I love how people like yourself think that these big corporations will not be making profits with green tech. They will just shift around the numbers.
That and you will be squealing like little girls when the prices of everything goes up to cover the diminished profits.
would it still not be safer to switch to more greener methods anyway?
A Punakaiki-based scientist has come up with a new theory on the cause of the hole in the ozone layer. Bill Hartley believes Starfish Prime, an American upper atmospheric nuclear test he witnessed in 1962, is partly to blame for the hole.
He connected the event with the hole in the ozone layer in the 1980s when he read Earth's Aura - a layman's guide to the atmosphere in which author Louise B Young discussed the destructive effects atmospheric nuclear testing could have on ozone.
"This rang a very loud bell for me in thatgradual depletion of ozone by chemical reactions would lead to a generalised thinning of the layer as the pollutants spread throughout the atmosphere, whereas massive nuclear blasts in the upper atmosphere would produce instant holes," Mr Hartley said.
He believed with the rise of the global warming phenomena everyone was overlooking the probability that the ozone hole was largely involved. Yet they were pointing the finger at fossil fuel burning emissions.
After some research he discovered the US tested 331 bombs in the atmosphere, six above the US and the rest above the Marshall Islands in the Pacific Ocean with some in the South Atlantic.
Also all we constantly hear how the Antarctic is getting warmer and we are all doomed..
It has to do with something quoted by the OP. Stratospheric temperatures.
Why if all the pollution is in the Northern hemisphere is not the Arctic ozone hole vastly larger than the Antarctic one?
