totse.com | Debunking myths about the ozone hole and greenhouse Hmm I dont know about this, what do you all think?
Technically, he's right about ozone "holes," but I think that's a red herring. CFCs might not create holes in the ozone layer, but they are widely believed to interfere with the formation of ozone that he describes in the upper atmosphere. He completely ignores this point. As for the global warming, I personally think it's very foolish to gamble on the speculative assumption that the results would be entirely benign.
This article contains some legitimate science mixed in with some scientific misconceptions. Don't put too much trust into it.
Well I am not surprised that the author did not put his name on the article.....I would not have either. He makes a couple of valid points, but his snide tone and absolute certainty he/she is right put me off. I agree, the holes are caused by lack of sunlight. The Ozone layer is created each morning, and disperses over night. But I also agree with the comment that it is foolish to bet our lives that the whole warming thing is benign. We may lose.
The ozone layer and global warming are two completly different issues that are too often bundled together in the media.I have not looked up Wikpedia as yet, but Micro$oft's Encarta entry for Ozone starts off by stating that ozone (O3) is formed in the presence of ultraviolet sunlight by reforming molecules of O2 into molecules of O3. It then goes on the mention CFC's that become unstable in the presence of UV sunlight in the stratosphere that cause the O3 molecules to reform back into O2 molecules.What it does not stated is what preocess is happening faster than thte other. We all know that difference between Encarta and Wikpedia is that when an idea is controversial Encarta will publish only the official press release version of events/ideas, whereas Wikpedia will state such ideas are controversial.
Actually, they are related, not directly though. http://en.wikipedia.org/wiki/Global_warming#The_relation_between_global_warming_and_ozone_depletion
Actually, the increased amount of UV and other high-enery light that hits the earth from a hole in the ozone will go and kill those little autotrophs in the ocean known as phytoplankton, which just happen to be the largest converter of CO2 to O2 at the moment. If the hole gets much bigger it'll just be a vicious cycle of we're all gonna die.
Dammit, I knew there was something I was forgetting. Thanks for reminding me, yes, that's true and very important.
It intrigues me that CFC's became dangerous just when the patents held by DuPont were about to expire and the replacement propellant gases - newly patented of course- had come on the market.In Australia you cannot take out patents on chemical formulas.Maybe it should be the same for the rest for the World.Actually most aerolsols never used CFC's as a propellant because they were too expensive. I wonder what the made anyone make a connection between aerosols and the ozone layer.Would not industrial pollution or vehicle exausts be a more obvious suspect?
I thought CFCs werent legal anymore? what about the stuff in axe deodorant, its like hydroflouracarbon(sp?)
if i "remember" correctly, weren't styrofoam "containers" a big "cfc" culprit back then? didn't macdonalds "switch" from styrofoam to whatever they "use" now because of cfc's? or "was" it something "else""?" the way that guy writes is hilarious
I could never work out that if CFC's were responsable for ozone depletion, why did it happen over the poles and not over the countries that were using aerosols?
The guy who wrote the original article was splitting terminological hairs to make an invalid point. My experience with the depleted ozone layer is as follows: I grew up and lived most of my life in Victoria, Australia (the state above the isle of Tasmania, on the mainland). The photography of the depleted ozone layer effects this region of the world. During the 70's, in my teens, skin cancer was not a media issue, hats were a fashion accessory, suntan lotion was oil to make the skin fry and brown, bathing costumes were speedos and bikinis. Cancer was sort of a rarity. These days, the sun seems to have a noticable "sting". As an avid sun-bather in my teens (I could be out in the sun for hours), now, 5 minutes is enough to feel a burn going on. By govt. decree, we are advertised to and almost forced to wear broad-brimmed hats, wear a 30+ to 45+ sunscreen cream and wear special bathing costumes reminiscent of the 1900's(long sleeved, comes to the knees) made of special fabric that totally blocks sunlight. Children are especially ecouraged to do this. Why? Because skincancer(s) have increased fighteningly (I've had one burnt off myself) and THERE'S A HOLE IN THE FUCKING OZONE LAYER! (or whatever it's called). Bastards who purport that there is no danger to the enviroment through hollow scientific mumbo jumbo are the same sick bastards working for the other side. Someone stole my ozone (sob)
