NASA | A Story of Ozone: The Earth’s Natural Sunscreen

The video discusses the importance of the ozone layer in protecting Earth from harmful UV radiation. It highlights the discovery of ozone-depleting substances like CFCs and the subsequent formation of the Antarctic ozone hole. The Montreal Protocol, an international agreement to phase out CFCs, is credited with preventing further ozone depletion. Current trends show a slow recovery of the ozone layer, but challenges remain with HFCs, which are potent greenhouse gases. The video emphasizes the need for continued atmospheric monitoring and potential regulation of HFCs to address climate change.
