The Ozone Hole is Getting Better. Really

Oct 19, 2006 6:57pm

If you live in Antarctica, yes, it might be a good idea this time of year to wear sunblock and some good sunglasses.  The strength of the stratospheric ozone layer is measured in dobson units.  A "normal" reading is 300; the ozone late last month over much of the Antarctic was 85.  Elsewhere on this planet, the news about the ozone layer is mostly reassuring, today’s headlines about it notwithstanding.  The ozone layer is slowly healing as ozone-depleting chemicals are phased out of production.  But it’s taking longer than originally projected.  You may have seen the piece I did this morning about it; if not, it’s HERE. For a short time (partly because of a slightly-too-strong headline on a NASA press release), I was getting frantic calls and emails from our other platforms.  I began putting together a piece for World News…despite my cautions that NASA was just reporting an aberration.  Cooler heads prevailed.  The broadcast led with the Dow Jones Industrials closing above 12,000. NASA offers some background HERE. (NASA image from Aura satellite.  Purple is thinner ozone.)
