In a major new paper in the influential journal Science, a team of researchers report strikingly good news about a thirty year old environmental problem. The Antarctic ozone “hole” — which, when it was first identified in the mid-1980s, focused public attention like few other pieces of environmental news — has begun, in their words, to finally “heal.”

“If you use the medical analogy, first the patient was getting worse and worse, and then the patient is stabilized, and now, the really encouraging thing, is that the patient is really starting to get better,” said MIT atmospheric scientist Susan Solomon, lead author of the study, and former co-chair of the United Nations’ Intergovernmental Panel on Climate Change.

And moreover, that patient — the Earth’s vital ozone layer — is getting better directly because of our choices and policies.

The initial, Nobel Prize winning discovery that ozone depleting chemicals called chlorofluorocarbons (CFCs) — carried in refrigerants, spray cans, foams and other substances — could damage the stratospheric layer that protects us from ultraviolet solar radiation (and thus, skin cancer) came in 1974. But it wasn’t until the sudden discovery of a vast seasonal ozone “hole” over Antarctica in 1985 that the world was shocked into action.
