        That does sound very convincing when you first read it, because the author is an excellent politician. But you should beware of people who use strawman arguments (the young man at the panel discussion) and unfounded ad hominem accusations (accusing the government of being infected by irrational environmentalists who want to destroy industry) in support of their case.

        Anyway, here's a generic rebuttal to the ozone naysayers [wunderground.com].

        Any scientific issue, no matter how rooted in facts it is, always has naysayers. Even the round earth theory had considerable opposition. For someone to dispute accepted scientific theory requires extraordinary evidence, and frankly this james p. hogan doesn't provide much in the way of actual evidence.

      Ozone is destroyed in a on going chemical process that is balanced by the creation of new ozone through natural mechanisms. The equilibrium level ozone is what we get. With CFCs introduced the equilibrium levels get shifted to lower concentrations. The introduction of man made ozone would be of little consequence as it couldnt be done a scale necessary to offset the CFC destruction. It would also need to be a continuous input which would make it very expensive and time consuming. A better plan, as we have done, is to attempt to reduce the CFCs and shift the equilibrium levels back to more favourable conditions.

      Ozone (O3) is basically created when UV light hits O2 molecules. When there's less ozone to block the UV rays, it stands to reason that more ozone would be created because more UV radiation is getting down to the level where the atmospher contains more O2. Even those that believe the hole is caused by human activity don't describe it as a problem caused by lack of ozone production; rather, it's theorized that atmospheric chlorine is breaking the ozone down faster than the UV + O2 interaction can replace it. Suggesting we "spray ozone" completely fails to appreciate the scale at which this is happening. We're talking BILLIONS OF TONS of ozone.

      Because ozone is created by the interaction of O2 and UV radiation. It's not some finite mass of rare elements. It's O3.

Though I would be surprised if there were not a natural cycle like all things in nature (magnetic poles, ice ages, volcanic activity ...), we do not need to play baby God with it.

The argument that there are no (or minimal) dangers ignores the fact that skin cancer exists. It ignores the fact that there is a hole in the ozone. The Montreal Protocol has been a major step forward to eliminating/minimizing those chemicals that we know deplete the Ozone layer.

    The other thing that may contribute to the Ozone layer growing back would be global warming, as the ozone depletion effect requires very cold temperatures to do the spectacular damage it has done to the pole. (see Univeristy of Cambridge [cam.ac.uk].)

      Is it just me, or is there always a charge of "the environmentalists are just trying to protect their funding" from the "it's junk science" crowd, without even a glimmer of acknowledgement of the irony? A single corporation that feels "threatened" by an environmental study makes more in a day than their environmentalist critics do in a year. If protecting your income is enough to get you to lie about something like this, organizations with a lot of money invested in, and a lot of profits riding on, the stat

Never mind that the Sun drives the earth's climate, let's make everyone think man does, and that we need to upgrade our toys to save mother earth!

    Could this have something to do with the increasing collapse of ice shelves [nsidc.org] in the Antarctic? Perhaps there is some relationship between the Ozone hole beginning to shrink and the collapse [nsidc.org] of the Larsen B Ice Shelf, which both coincidentally happened in 2002. Maybe the collapse and accellerated [nsidc.org] glacier movements triggered some environmental chain reaction that affected the Ozone hole, but in a superficial way that temporarily masks a continued climate change.

    Of course scientists caution this would have to continue for at least a couple more years to be a trend or anything to get excited about.

    Isn't it funny that when there is good news about the climate, "scientists" tells us that we shouldn't "get excited about it," yet when there is apparently bad news, these same scientists demands that we must act "before it's too late."
