NASA | Why is the Ozone Hole Getting Smaller?

The video discusses the history and recovery of the ozone layer, highlighting the impact of the 1987 Montreal Protocol in reducing ozone-depleting substances. It notes the current size of the ozone hole, which is smaller than in previous years, and explores the role of rising stratospheric temperatures in this recovery. Scientists are investigating the relative contributions of reduced chemicals and temperature changes to the ozone layer's improvement.

Discuss the relationship between temperature variations and the size of ozone holes.
