Why you don’t hear about the ozone layer anymore
Vox・6 minutes read
The discovery of the ozone hole over Antarctica in 1985 prompted urgent action, leading to the Montreal Protocol of 1987 and a global phase-out of CFCs to protect the ozone layer from complete destruction by 2050. Despite progress in healing the ozone layer, the focus now shifts towards phasing out HFCs to combat climate change, highlighting the ongoing need for substantial environmental solutions.
Insights
- The discovery of the ozone hole over Antarctica in 1985, caused by man-made Chlorofluorocarbons (CFCs), prompted urgent action due to the significant threat posed.
- The Montreal Protocol of 1987 led to a rapid global phase-out of CFCs, resulting in a drastic reduction in ozone-depleting substances consumption, showcasing the effectiveness of international cooperation in addressing environmental crises.

Ozone Layer Crisis: From Threat to Recovery
- In the 1980s, a hole in the ozone layer over the South Pole, the size of the continental United States, threatened the protective ozone shield, putting all life at risk.
- Scientists warned of complete ozone layer destruction by 2050, leading to ecosystem collapse and increased skin cancer rates.
- The discovery of the ozone hole over Antarctica in 1985, caused by man-made Chlorofluorocarbons (CFCs), prompted urgent action due to the significant threat posed.
- The Montreal Protocol of 1987 led to a rapid global phase-out of CFCs, resulting in a drastic reduction in ozone-depleting substances consumption.
- While the ozone layer is now healing, the focus has shifted to phasing out Hydrofluorocarbons (HFCs) due to their contribution to climate change, emphasizing the ongoing need for substantial solutions to combat environmental challenges.
