Concerning the new threat to the ozone layer, a reader remarks:
Not too surprised to find that chlorinated carbons have similar effects as fluorinated carbons. Fluorine and chlorine have similar electro-negative properties, being the 2 lightest and most reactive halogens.
The article suggested that chlorinated carbons were not expected to survive long enough after manufacture & release to make it up to the ozone layer. The weather in the area, however, apparently funnels those chemicals right to the ozone layer much faster than suggested.
