CFCs and their effect on the ozone layer: The Montreal Protocol and consequences for physiciansMatthys, HMatthys H. CFCs and their effect on the ozone layer: the Montreal Protocol and consequences for physicians. Eur Respir Rev 1997; 7:29-31....
The Montreal Protocol on Substances that Deplete the Ozone Layer 1 is an agreement to reduce production and emissions of chlorofluorocarbons (CFCs) motivated primarily by the need to protect the Earth's ozone layer. The possible effects of CFCs on global climate were noted as an additional cause...
[Alleviative effects of nitric oxide on the biological damage of spirulina platensis induced by enhanced ultraviolet-B]. Continuing depletion of the stratospheric ozone layer by atmospheric pollutants,in particular chlorofluorocarbons(CFCs), has resulted in an increasing inci... LG Xue,SW Li,SJ Xu,...
10found that the surface temperature response to a large forcing of CFCs and N2O had very similar geographical patterns as the response to CO2and CH4forcing.
After the sign of the Montreal Protocol, with the discontinued production of CFCs, the content of CFCs in the atmospheric was reduced slowly. But the recovery of the ozone layer will take some time. The increase of the HCFCs and the HFCs exacerbates the greenhouse effect. This article describ...

Taken together greenhouse gases are expected to warm the planet by 2.5 to 8 degrees Fahrenheit by the end of century. HFCs, CFCs and HFCs contribute an estimated
