Ozone’s Long Path to Recovery

Does a smaller hole mean that Antarctic ozone is recovering? Not yet, say NASA scientists. A deeper look at the ozone hole shows that for now weather still has a bigger influence on the size of the ozone hole than policies that limited emissions of ozone-destroying chemicals.

Measurements Show Reduction in Ozone-Eating Chemical

New research from NASA scientists shows that the amount of chlorine in the stratosphere over the South Pole is declining at the same time that ozone holes are becoming less severe.
