In 2015, scientists at NASA predicted that the Ozone Hole would be half closed by 2020. That hasn’t happened. Other ...
The ozone hole over Antarctica is the seventh smallest it’s been since the early 1990s. Recovery began with the Montreal Protocol, which ended the production of all chlorofluorocarbons (CFCs) in 1987.
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 ...
Aerosol spray cans may not seem all too dangerous, but they've actually wreaked havoc. So badly, in fact, that the world at ...
As well as the ozone layer, CFC-11 has a warming impact ... Developing countries were given much longer to replace the gases. So while most of the richer countries got rid of CFC-11 in the ...
It’s not all bad news for the ozone layer, however. Since the Montreal Protocol outlawed most production of CFC gases that harmed the ozone layer, we’ve seen gradual recovery from earlier ...
Two of the gases are accumulating at a rate that is causing concern among researchers. Worries over the growing ozone hole have seen the production of chlorofluorocarbon (CFC) gases restricted since ...

The ozone layer acts as a stratospheric shield ... scientists first started ringing alarm bells about the impact of chlorofluorocarbon (CFC) gases which were commonly used as coolants in ...
the Montreal Protocol has benefited climate through the regulation of CFCs and other ozone-depleting compounds, which also function as greenhouse gases. Clearly there is a need for discussion ...
CFCs are greenhouse gases containing carbon, hydrogen, chlorine and fluorine and have been studied to contribute to ozone depletion. The ozone layer in the Earth's atmosphere blocks the harmful ...
