Ozone Hole Recovery Could Case Antarctic Warming

This is an interesting, although dense, article about how if the ozone hole in the Southern Hemisphere begins to recover it could lead to warming in Antarctica. Currently, Antarctica as a whole is not warming as much as it has in other areas in the Southern Hemisphere. Apparently the ozone hole recovery would weaken the winds in the Western Antarctic and that somehow keeps the Antarctic isolated from the rest of the region's warming. Basically the article leaves me confused on what the connection between ozone hole recovery and warming in Antarctica and in the end the article mentions global warming caused by greenhouse gases is more likely to cause warming in the Antarctic.
