Discovery of the Ozone Hole (1985): Unveiling Human Impact on Earth's Protective LayerDiscovery of the Ozone Hole (1985): Unveiling Human Impact on Earth's Protective Layer

In 1985, a team of scientists from the British Antarctic Survey, led by Joe Farman, made a groundbreaking discovery: a vast hole in the ozone layer above Antarctica. This ozone depletion was unprecedented, indicating a severe environmental issue caused by human activities. The culprit was identified as chlorofluorocarbons (CFCs), chemicals used in refrigerants, aerosols, and industrial processes. These compounds were found to break down ozone molecules in the upper atmosphere, leaving a vulnerable gap in Earth's natural UV protection.

The discovery of the ozone hole spurred international concern and action. The Montreal Protocol, signed in 1987, aimed to phase out CFCs and other ozone-depleting substances worldwide. Over the following decades, scientific monitoring showed signs of recovery in the ozone layer, demonstrating the effectiveness of global cooperation in environmental protection.

In 1985, scientists observed a significant thinning of the ozone layer above Antarctica, revealing the detrimental effects of chlorofluorocarbons (CFCs) on the environment. This discovery prompted global efforts to phase out ozone-depleting substances.
