Ozone Hole Over the Arctic Closes

Have you heard that the ozone hole over the Arctic has closed up? It's definitely a reason to celebrate during times when we often don't feel as if there's much joy to go around. It was the largest hole to have opened up, but it closed just as fast as it appeared, leaving scientists to wonder just what's going on.

We can't blame the coronavirus for this joyous occasion, but the intense polar vortex that occurred. It would be interesting if this led to some ideas about repairing the ozone in other ways, but it sounds like it's something that occurs every decade as part of a natural phenomenon.
