The chemical reactions are as follows: The net result (2O3 à 3O2) is that one chlorine atom destroys two ozone molecules and is regenerated in the process, allowing it to react over and over again. So ...

NASA modelling shows that the hole in the ozone layer would have covered the entire Earth by 2060 if CFC production had ... which could undergo chemical reactions with other molecules in the ...

Scientists have identified four new man-made gases that are contributing to the depletion of the ozone layer. Two of the gases ... of chlorofluorocarbon (CFC) gases restricted since the mid ...

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 ...

As well as the ozone layer, CFC-11 has a warming impact. Researchers estimate that if the use of the chemical continues, it would be the equivalent of CO₂ from 16 coal-fired power stations every ...
