<The other colder temperatures are in the stratosphere, not at the surface, and they have declined from the normal -55 degrees fahrenheit down to as low as -80 degrees fahrenheit which is why clorinated molecules can successfully attack the ozone layer. > Ray, our resident scientific advisor, wouldn't the lower temperatures make it tougher for the chlorinated molecules to react with the ozone? The way to accelerate chemical reactions is to apply heat, not cold. If you can get things cold enough, all chemical reactions cease, because the molecules have stopped moving and don't bump into each other and if they touch, they don't have sufficient energy to get over the usual reaction initiation energy. The ozone is depleted in winter not because the air is colder. You are confusing cause and effect. The air is colder in winter because there isn't sunshine in Arctic and Antarctic winters, which is why nights are longgggggg and dark and cold. When the sun goes out, things get cold. When there is sunshine, there is ultraviolet light and it's the ultraviolet light which turns oxygen into ozone. In winter, the sun goes out and those naughty CFCs can do their evil work of gobbling ozone. In summer, they can't keep up because although the depletion reactions can go faster in the warmer air, they can't keep up with the tsunami of ultraviolet light from the all day intensely bright sunshine; days are as long and bright in summer as the nights are long and dark. The ozone depletion business is unrelated to CO2 "saturation" of the atmosphere [saturation is stretching the point when CO2 is still measured in parts per million and is still not making me breathe and plants still like to have CO2 enrichment]. <Perhaps you could spend a bit more time learning the science of global warming >. Ozone depletion is nothing to do with global warming. Ozone depletion in fact causes more ultraviolet light to reach ground level and plants use ultraviolet light to provide energy to process CO2, using their chlorophyl, into cellulose and other stuff. Which means the more ozone depletion there is, the more CO2 is absorbed and the less greenhouse effect there is. People often confuse the ozone layer with the greenhouse effect, and they used to throw in acid rain too [when it was more fashionable] in an atmospheric witch's cauldron of mystical mumbo jumbo. "Woe is us! With the greenhouse effect caused by the ozone layer being suffocated by CO2, the hot acid rain will fall, raising sea levels, melting polar bear habitats and putting Venetians up to their waists in water." As nature demonstrated on Boxing Day, it's the sudden sea level rises which cause the harm. Meanwhile, the tsunami of H5N1 gathers strength and the Year of the Feather Duster manoeuvres are being planned by China and Russia [not to mention North Korea]. Not to mention financial implosion into a black hole of TeoTwawki as defined by Jay. 2005 could turn out to be a LOT of fun! I don't think the greenhouse effect will be a major issue. The ozone layer won't be either [though swarms of Kiwis will have skin cancers cut out]. Who can remember acid rain? Mqurice
