Good news: The ozone hole above the Antarctic closed at the end of December.

The ozone layer, located at an altitude between 10 and 40 kilometers, protects us from the harmful effects of ultraviolet rays from the sun. In 2019, it had been significantly less extensive: the last two seasons of the ozone hole demonstrate its year-to-year variability and improve our understanding of the factors responsible for its formation, extent, and severity.
