Destruction of Ozone Layer is Slowing After Worldwide Ban on CFC Release
The rate at which ozone is being destroyed in the upper stratosphere is slowing, and the levels of ozone-destroying chlorine in that layer of the atmosphere have peaked and are going down -- the first clear evidence that a worldwide reduction in chlorofluorocarbon pollution is having the desired effect, according to a new study.
"This is the beginning of a recovery of the ozone layer," said professor Michael Newchurch of the University of Alabama in Huntsville (UAH), the scientist who led the ozone trend-analysis research team. "We had a monumental problem of global scale that we have started to solve."
