the ozone layer’s recovering

tue, 30 may 2006 - over the last few decades, scientists have been tracking the depletion of the ozone layer in the earth’s atmosphere. a large hole still opens up over antarctica, but ozone levels worldwide have stopped declining. the question is why. the relatively recent reduction of ozone-destroying gasses shouldn’t make an improvement so quickly. nasa scientists think that atmospheric wind patterns could be transferring ozone around the planet, helping with the recovery. at this rate, we’ll return to 1980 levels between 2030 and 2070.
