Ozone layer safe “for 100 years”
Further evidence that the chlorofluorocarbons 11 and 12 are a greater threat to the ozone layer in the stratosphere than any other chemical compound is cited in a report published by the Department of the Environment’s Central Unit on Environmental Pollution (CUEP). If the 1973 rate of CFCs 11 and 12 is continued, says the report, a maximum depletion of about 8 per cent in the ozone layer will occur in about 100 years’ time. This would cause an increase in ultraviolet radiation reaching the ground of about 16 per cent. To put this…
