Scientists Haven’t ‘Saved’ the Ozone Layer

“In 2015, scientists at NASA predicted that the Ozone Hole would be half closed by 2020. That hasn’t happened. Other scientists have forecasted that the hole will not begin to disappear until 2040 or later. But the longer the hole persists, the greater the likelihood that the ozone layer is dominated by natural factors, not human CFC emissions.”
Another year has passed, and that stubborn Ozone Hole over Antarctica refuses to go away. Data from the National Aeronautics and Space Administration (NASA) shows that the area of the Ozone Hole remains about the same as it has been over the last 30 years. But will scientists admit that they didn’t save the ozone layer?
Background
Ozone is a gas made up of three oxygen atoms (O3). Ninety percent of the ozone in the atmosphere is found in the stratosphere, a layer of atmosphere between about 10 and 50 kilometers in altitude. The amount of ozone in the atmosphere varies with time of year.
Dr. Mario Molina and Dr. Sherwood Rowland of the University of California published a paper in 1974 warning that industrial chlorofluorocarbon (CFC) pollution was destroying the ozone layer in Earth’s stratosphere. CFCs were gases used in hair spray, refrigerators, and insulating foams.
