Ozone Depletion Slows

The Montreal Protocol is finally having an effect. Since CFCs were banned in 1987, the ozone layer has been steadily decreasing, but recent research notes that the rate of ozone depletion has finally reversed itself and begun to slow down. Estimates are that the ozone layer should be back to “normal” by about 2040, but back to pre-1980 levels within 15-20 years.
