In 2015, scientists at NASA predicted that the Ozone Hole would be half closed by 2020. That hasn’t happened. Other ...

Aerosol spray cans may not seem all too dangerous, but they've actually wreaked havoc. So badly, in fact, that the world at ...

Researchers say that they have pinpointed the major sources of a mysterious recent rise in a dangerous, ozone-destroying chemical. CFC-11 was primarily used for home insulation but global ...

Humans have been depleting the ozone layer with chemical products. The unintentional experiment started in the late 1920s, when Thomas Midgley and other industrial chemists began to produce ...

In 1974, Mario Molina and Sherwood Rowland published a paper in Nature detailing the effects of chlorofluorocarbon (CFC) gasses on atmospheric ozone. The paper pointed out that CFCs, which were ...

Chlorofluorocarbons, along with other chlorine- and bromine-containing compounds, have been implicated in the accelerated depletion of ozone in the Earth's stratosphere. CFCs were developed in the ...

The ozone layer had been damaged by man-made chemicals called chlorofluorocarbons (CFCs). The ozone layer starts about six miles above Earth. It is a colourless form of a specific type of oxygen ...

NASA modelling shows that the hole in the ozone layer would have covered the entire Earth by 2060 if CFC production had not been outlawed by the Montreal Protocol in the 1980s. Credit: NASA ...

Attention focused initially on chemicals with higher ozone-depletion potentials including CFCs and halons. The phase-out schedule for HCFCs was more relaxed due to their lower ozone-depletion ...
