Unusual Winds Drive a Small 2019 Ozone Hole

The video discusses the ozone hole, its causes, and seasonal fluctuations. It highlights the role of CFCs in ozone depletion and the impact of weather patterns, particularly the polar vortex, on the ozone layer. Despite the small ozone hole this year due to unusual weather, the ozone layer shows signs of recovery thanks to the Montreal Protocol. NASA and NOAA's research efforts are also mentioned.
