Understanding the Ozone Layer: Threats and Monitoring

The video discusses the thinning of the ozone layer, which absorbs harmful UV radiation. It explains how polar vortexes and ice crystals contribute to ozone depletion, particularly due to chlorofluorocarbons (CFCs). Surface-level ozone, formed by pollutants, can harm respiratory health. The Netherlands Royal Institute of Meteorology monitors the ozone layer, which is under threat from CFCs, especially over Antarctica. Satellite data shows the ozone hole's size and changes. Despite reduced CFC use, the ozone hole persists due to chlorine atoms' destructive capacity.
