UN Environmental Summit in Johannesburg S Africa


  • Some news on the hole in the ozone layer.
    It was smaller the last years, but that definitely was due to other temperatures.

  • Scientists are predicting a large ozone hole over much of Antarctica this spring.

    Parliamentary Secretary for the Antarctic Dr Sharman Stone said that a larger ozone hole meant that people were likely to be at greater risk of sunburn and should take precautions.

    Question…if the hole is only above Australia, how many people are going to get sunburned there?

    “Our scientists are telling us that the trend in atmospheric readings above Antarctica are similar to those observed in 2000, when the ozone hole was of record size and about three times the size of Australia,” Dr Stone said.

    “This is the legacy of ozone depletion over many years and reinforces just how long it can take to repair the damage.

    If it only took 3 years to shrink the hole that much, it’s not that long of a time, is it?


  • I hate to say it(NoIdon’t!), but Xi was right 10 months ago(even without good sources at the time.)

    ‘Temperature’ is temperature whether is air, water, or soil measurement.

    Though this year is loopy in the US and Europe(from what I’ve read and heard I hope no one requires SOURCES for that.) Any other continents having a bad summer/winter(South of the equator. 😄 )

    Has the Antarctic melted yet? Whatever happened to that iceberg the size of Australia? 😛

    No sources necessary, already been confirmed in other thread, therefore it’s true. :lol: I was going to try and include some sources in my other post, but I was too lazy to find any that F_alk would say were wrong. :roll: So I just gave up and went with my questions from the web site he found. (Should be a better debate)


  • Very magnamanous 😄 of you, GI. But I’m afraid we haven’t heard from the peni* gallery yet. Ew, ew! Did I say that!(Rather pithy today[no lisp.])

    Okie-dokie! If you are over there… is this an especially hot summer for the desert?!?


  • @Grigoriy:

    Question…if the hole is only above Australia, how many people are going to get sunburned there?

    The hole is over Antarctica (see what you quoted), which is pretty close to Australia. The people there know the problem, and try to live with it as good as possible since the early 80s.
    Australia is the country with most skin cancer. 2 of 3 Ozzies will /have been treated for that in their live time. Melanoma are more common than lung cancer. The mortality rates are about twice as high as those in the Greater San Francisco Bay Area.

    If it only took 3 years to shrink the hole that much, it’s not that long of a time, is it?

    There was talk of a “record size” in 2000. The hole in 2002 was the smallest since 1988. There was no notion of “how much” it actually was then.
    So, we can see that the hole there is od different size for temperature reasons. That does not at all change the fact that it (a) is there and (b) caused by us humans.

    sigh why don’t you go to Australia and do not protect yourself?

    I don’t think GI was doubting that (t’s a fact, not an opinion), but his post was in response to this… “This is the legacy of ozone depletion over many years and reinforces just how long it can take to repair the damage." - that being the opinion.

    1)A source is only necessary when starting a thread, once we get going we can just rely on our differences to keep it going. :lol:

    2)I couldn’t reliably say…it’s my first (and hopefully only) summer over here, and while I couldn’t say it’s an especially hot summer, I will say that I have developed a fear of living without AC, and I start shivering when the temperature hits 70 degrees (21 deg. C), when I used to start avoiding work at that temperature because of the heat.

    Oh, ok…
    Well, for that, we can see that even though we might have thought it was getting better over the last years, this does not seem to be the case at all. We still reach new record sized holes, even thogh we stopped putting fluor-chlor-CH into the atmosphere… about 10 years ago?


  • However can the number fluctuate so much between smallest since 1988 in 2002 and largest recorded ever (I’m assuming 2003)?


  • The 2003 will be of about the record size as it seems, and the predictions are quite reliable. So, the answer is “yes, it can fluctuate that much”.
    Something that usually is used against environmentalists, as some (other) fluctuations are normal, then the effect could be “just fluctuations”. The other side of the medal is never heard (not even by environmentalists): the same fluctuations could be “favoring” us, and the real man-made effect is much worse….
