Climate change experts have predicted the hole in the Earth’s ozone layer will fully heal within 50 years, a UN report has revealed.
Scientists first discovered damage to the ozone layer in the 1980s, identifying chloroflourocarbons, or CFCs, as the main contributor, previously common in refrigerators, aerosol cans and dry cleaning chemicals.
Banned globally under the Montreal Protocol of 1987, a decline of CFCs in the atmosphere means that the Earth’s ozone layer is expected to fully recover some time in the 2060s.
