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 ...

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 ...

In contrast to chemicals containing chlorine and bromine, nitrogen oxides destroy ozone globally between 25 and 35 km. Nitrous oxide behaves in a similar way to chlorofluorocarbons (CFCs): it is ...

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 ...

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 ...

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

CFCs are long-lived chemical compounds that rise into the stratosphere, where they are broken apart by the Sun’s ultraviolet radiation, releasing chlorine atoms that destroy ozone molecules.

The connection between CFCs and the ozone layer Almost five decades ago, three chemists — Mario Molino, Sherwood Rowland, and Paul Crutzen — warned that chlorofluorocarbons (CFCs) pose a ...

The ozone hole above Antarctica has been remarkably massive and long-lived over the past four years and chlorofluorocarbons (CFCs) are not the only things to blame, said researchers in their study ...

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 ...

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