      • True, but although the ozone hole does pass through shortwave radiation, it actually results in less absorption of longwave radiation. So in fact the ozone hole results in cooling rather than warming (stratospheric ozone is a greenhouse gas). The main impact of ozone thinning is likely to be on the location of the jet stream. Reference to this is Shindell and Schmidt, Geophys. Res. Lett, Sept. 25, 2004.

    The article does not say that severe weather causes ozone thinning. In fact, it says the opposite: the severe weather increases ozone thinning. The only result of ozone thinning that is mentioned is increased UV rays, and thus an increased risk of skin cancer.

    • Warming the troposphere raises the tropopause, which means that the stratosphere (the zone which is not mixed by convection, and can thus support ozone) gets thinner and colder. This gives less room for ozone and more clouds etc. to catalyze its destruction.

      If you really wanted to be funny, you'd suggest fighting warming and ozone depletion with sulfur emissions (which make reflective clouds) and NOx and HC emissions (to replace stratospheric ozone with ground-level ozone, aka smog).

      • Not only that, but increasing greenhouse gas concentrations (which normally goes along with tropospheric warming) decreases the rate at which heat from the ground reaches the stratosphere, so the stratosphere actually gets colder above and beyond the effect of just raising the tropopause.

        It's like putting better insulation on a house. The inside of the house gets warmer, but the outside gets colder as less heat gets leaked out.

    For those of you who don't know, CFCs are an all-around useful chemical. Not only is it completely harmless to human (save asphyxiation), it retards all kinds of fires instantly. The Navy used to use it on all of their ships to put out fires instantly. Guess what? Since it was deployed. hardly anyone got injured due to fire. Nowadays, fires on our Navy vessels are too com
    • Here's three good reasons why the hole is still there:

      1 - CFCs are very long lived, and it takes decades for CFCs to leave the atmosphere once released.

      2 - Other countries are still producing CFCs, though many are phasing it out.

      3 - There are still legacy appliances and manufacturing processes that use them.

      Using CFCs again would just make things worse, and no ozone would mean a lot more than just having to wear sunblock in the middle of winter, and plants (which we depend on for food) and animals are a

        (1) Refrigerators and air conditioners would be a lot more efficient and cheaper too. They would be safer as well.

        (2) Places where fire is dangerous can install the fire extinguishers that use CFCs, saving hundreds if not thousands of lives. If such a system were installed in the World Trade Center, the building would not have burned and it would not have collapsed. Of course, if they had finished the installation of asbestos, it would not have fallen either, but government strikes

        • Actually, the manufacture of the ozone would be supremely easy. The delivery of it would be difficult, not only for reasons mentioned, but for making sure it doesn't get released near the surface. Remember, ozone isn't exactly what people like to breathe ... I lived in Southern California for a number of years, and one of the key air quality alerts was the ozone alert.

    • Even in the stratosphere, ozone is fairly short lived. It is destroyed in the process of absorbing UV radiation, and is regenerated rapidly.

      The only reason that CFCs are such a big problem is that they can destroy about 100,000 ozone molecules before they finally leave the environment a few decades later. A pound of CFCs will destroy tens of tons of ozone in the course of its life, so even if ozone was long-lasting, it would take a crazy amount of ozone to replace what CFCs destroy.
  • No sunbathing at the north pole this year.
  • I have to say, these articles do help the everyday sheep learn what the ozone is, and what it does. I will always remember meeting a lady at the gas station. She was driving herself (and only herself) in her huge SUV. She was then commenting on how interesting the front page article about global warming was, and that I "should read it". I would like to point out that I was driving a 40mpg little car at the time (and still have it, 9 years later).
