    At last - a good news story on the environment!

    Thanks to the ban on CFCs in aerosols - which I imagine many posters here ridiculed and opposed - the hole in ozone layer is getting smaller. By 2050, the hole should be gone altogether.


    A University of Canterbury atmospheric researcher this week revealed that New Zealand's ozone hole - responsible for a 14 per cent jump in melanoma over the past decade - is shrinking for the first time in 30 years.

    "Ozone levels above Antarctica are projected to return to 1980 levels - previous to the ozone hole - after 2050," said Dr Adrian McDonald.

    Shhhhh............... Say it quietly, or the wingnuts here will be bemoaning the fact that we are polluting the upper stratosphere with ozone.

    It's also a required belief among the denialist political cult to deny CFC ozone depletion theory. Totally barking insane, but they have to deny it, or they get purged from the cult, and that's like a death sentence to a denialist herdbeast.

    Why? Because it demonstrates a case of scientists being absolutely correct in their consensus, and then pushing to implement political solutions that prevented a catastrophe. It makes scientists look good, therefore it enrages denialists.

    So, just how did these scientists "repair" the ozone hole?

    Saran wrap?...Sunscreen?...A low fat high fiber diet??...Magic fucking beans?

    That hole has gotten smaller in the past. And it has gotten bigger. This time last year it was bigger.

    Ozone layer hole over Arctic in sudden expansion | Environment | guardian.co.uk

    Yes it was foolish to believe that a housewife in New Jersey could affect the ozone layer with her hairspray.

    Of course having no hole in the ozone layer increases global warming. So maybe we should all start using hairspray!
    Ozone hole healing could cause further climate warming

    The hole may actually be caused by global COOLING. Maybe we should all get out there and drive around in circles and throw those plastic bottles away.

    Ozone hole above the Arctic has actually been caused by COLD weather | Mail Online

    The facts are, environmentalists are wackos who foretell "climate change" by throwing bones and reading the entrails of dead chickens.

    Press Release

    11 October 1995

    The Royal Swedish Academy of Sciences has decided to award the 1995 Nobel Prize in Chemistry to

    Professor Paul Crutzen, Max-Planck-Institute for Chemistry, Mainz, Germany (Dutch citizen),

    Professor Mario Molina, Department of Earth, Atmospheric and Planetary Sciences and Department of Chemistry, MIT, Cambridge, MA, USA and

    Professor F. Sherwood Rowland, Department of Chemistry, University of California, Irvine, CA, USA

    for their work in atmospheric chemistry, particularly concerning the formation and decomposition of ozone.

    The ozone layer - The Achilles heel of the biosphere

    The atmosphere surrounding the earth contains small quantities of ozone - a gas with molecules consisting of three oxygen atoms (O3). If all the ozone in the atmosphere were compressed to a pressure corresponding to that at the earth's surface, the layer would be only 3 mm thick. But even though ozone occurs in such small quantities, it plays an exceptionally fundamental part in life on earth. This is because ozone, together with ordinary molecular oxygen (O2), is able to absorb the major part of the sun's ultraviolet radiation and therefore prevent this dangerous radiation from reaching the surface. Without a protective ozone layer in the atmosphere, animals and plants could not exist, at least upon land. It is therefore of the greatest importance to understand the processes that regulate the atmosphere's ozone content.

    Paul Crutzen, Mario Molina and Sherwood Rowland have all made pioneering contributions to explaining how ozone is formed and decomposes through chemical processes in the atmosphere. Most importantly, they have in this way showed how sensitive the ozone layer is to the influence of anthropogenic emissions of certain compounds. The thin ozone layer has proved to be an Achilles heel that may be seriously injured by apparently moderate changes in the composition of the atmosphere. By explaining the chemical mechanisms that affect the thickness of the ozone layer, the three researchers have contributed to our salvation from a global environmental problem that could have catastrophic consequences.

    Uh.huh...How did the awarding of the Nobel Prize "repair" the ozone layer?

    After that, how do any of those prizewinners 'splain the varying nature of the dreaded ozone hole since the worldwide ban on CFCs?

    C'mon, champ, bring it.
