Ozone Hole Splits in Two

DaDigz writes "CNN is reporting here that the hole in the ozone layer above Antarctica has split in two "like a giant amoeba". It's not yet been determined whether this is a result of unusual weather patterns or whether the ozone layer is recovering. One can hope, though, that this may be a sign of a mend in the ozone layer."

    Everybody knows that any ozone hole data means nothing. Including the data that termed it a hole in the first place.

    I believe my math geek friends would characterize this as, "proof by assertion" ?

    You aren't making this assertion from knowledge. Your assertion is coming from your intuition. Everybody doesn't know this. I don't know this. Neither do a lot of climate experts. Neither do you. You don't have knowledge. You have a belief about the ozone hole -- based on your intuition.

    Well intuition failed us when it came to the ozone hole.

    Here are some RISKS articles, from 1986, shortly after the ozone hole was first recognized, to back me up.

    Recently, it was disclosed that a large hole in the ozone layer appears once a year over the South Pole. The researchers had first detected this hole approximately 8 years ago by tests done at the South Pole itself.

    Why did they wait 8 years to disclose this disturbing fact? Because the satellite that normally gives ozone levels had not reported any such hole and the researchers could not believe that the satellite's figures could be incorrect. It took 8 years of testing before they felt confident enough to dispute the satellite's figures.

    And why did the satellite fail to report this hole? Because it had been programmed to reject values that fell outside the "normal" range!

    What happened here is that intuition failed. Intuition failed the physicists who specified the sanity filters. And, I would argue, that intuition failed you too.
