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.

The growth of the ozone hole appears to have stopped thanks to the banning of most ozone-depleting chemicals.

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.

Recent observations from satellites and ground stations suggest that atmospheric ozone levels for March in the Arctic were approaching the lowest levels in the modern instrumental era.
