Yesterday, though, Harvard scientists hit us with some bad news: It looks as if climate change could actually cause the depletion of the ozone layer to resume on a wide scale, with grim implications for the United States.


Quote:
In the warmer air above the U.S., the researchers measured that the local presence of water vapor increased the rate of ozone erosion as high as one hundredfold.


Basically increased warming allows summer storms to push moisture higher into the stratosphere which makes it much easier for chlorine radicals to destroy ozone.

Not once did the story or the abstract mention Dobson Units. Any story lacking measurements strikes me as disingenuous. But wait there is more.

Quote:
Because this mechanism has only been detected now, there are no historical data about how much water vapor has been moved upward by such storms over time, and so the researchers can’t say just how much total increased ozone depletion has occurred so far. But their concern is the future.


So toss in a scary story, but CYA say we don't really know, but the future looks really scary. An all to familiar dishonest template really.

Why would a story mention unist of measure that most of the readers may not recognize and therefore not add anything and take space? The abstracts often do not mention units of measure unless the paper is directly about measurements.

Dishonesty by being honest about the historical data when discovering a new impact on the ozone layer? Just yesterday the weather report was pointing out the increased height of some of the storm systems this summer because it was unususal, which would make the concerns very valid.

A link to original paper is provided but is behind a pay wall, I have no doubt the paper contains enough data to support Anderson's conclusion that high level moisture is a further mechanism that adds to Ozone loss.

I live in Australia where the current statistics indicate that 2 out off 3 people will develop skin cancer during their life time.
I think that increased levels of UV are a very scary story.

Wow! I am sorry for our Aussie friends. Those are horrible statistics, and I hope more sunscreen use, white hats and white long sleeves, all can help reduce that number of cancers. I have to do that living at high altitude with the thinner ozone layer, plus anti-cancer supplements like turmeric, essiac, and whole lemons.
