Antarctic Ozone Hole smallest in five years

Antarctic Ozone Hole smallest in five years. A blind copy-and-paste from Anthony Watts from the scientific journal MSNBC. A smaller ozone hole is indicative of success in altering human emissions (chlorofluorocarbons), but a short-term trend is probably not statistically significant.

Doesn’t fit the narrative, does it, Anthony? Slapping on a bit more cover for the anti-science?

  1. Wow, the CFC-ozone destruction denialists are out in extreme strength in the comments.

    [Gubmint never did nuthin’ good. – Ben]

  2. As always it’s the comments that make e.g.

    “Until we understand the physics (and the history) better, there’s no way anyone can say that limiting man-made chlorofluorocarbons has any effect on the ozone “hole”. Was there a “hole” there before we could observe such things? Nobody knows.”

    It’s funny how little “we” understand when you’re reading WUWT

  3. CHEMISTRY……….actually.

    Atomic chlorine (Cl-) is one of the free radical catalysts that can destroy ozone.
    Rowland (chemistry professor) & Molina (his postdoctoral associate) in 1974…

    “…concluded that CFC’s (chlorofluorocarbons) would reach the atmosphere where they would be dissociated by UV light, releasing Cl atoms.”

    “…within three years most of the basic assumptions made by Rowland and Molina were confirmed by laboratory measurements and by direct observation in the stratosphere. The concentrations of the source gases…and the chlorine reservoir species…were measured throughout the stratosphere, and demonstrated that CFC’s were indeed the major source of atmospheric chlorine, and that nearly all of the CFC’s emitted would eventually reach the stratosphere…” Wikipedia
