m.com (Thumper!) in article 2326 in ca.environment says: >>Example: CFCs. Supposedly, CFC's are ruining the ozone layer, >> and have to be stopped before the entire human race becomes >> blackened to a crisp. So much pressure and eco-doodoo is said >>that the mighty Congress outlaws CFC's and forces the people >>to buy expensive, unreliable "no CFC" air conditioned cars,and >>makes it expensive and difficult to repair older A/C units.Then >>what happens? Mt. Pinutubo explodes in a fiery volcano, and >>scientists... REAL scientists, not the "we think, therefore it >>must be" eco-wannabe-scientists, take some measurements, >>and conclude that just the ONE volcanic eruption has put 10 >>times more CFC's into the atmosphere than mankind has in the >>however many years of existence. mankind has. more stuff deleted The most frightening part of this post is the subject: Misinformation amongst the masses. Man this dude should really read do a little homework and then read his post again. Maybe then he (she?) could tell me about misinformation "amongst" the masses. I am a graduate student trying to do real science here at UCSD and I have many contacts down at SIO (Scripps institute of oceanography) where there are many people applying the scientific method to ecology and climate. SIO runs the data collection and analysis for many satellites and other observation platforms. If the eruption of Mt. Pinutubo had injected 10X more CFC's we would certainly know it. The photochemical degradation products of CFC's are easy to detect with remote sensing devices such as passive thermal infrared sensors. Also due to the known lifetime of CFC's in the troposphere (the lowest 5km or so) we would have measured a huge spike in the tropospheric concentration which is independently measured at many many labs around the world. Now I don't know what REAL scientist are but apparently they don't publish in peer reviewed journals, possibly they are the same creed that first argued (and still argue) that CFC's couldn't possibly reach the stratosphere because they are heavier than air. Can you believe it! this was actually argued on the senate floor. It makes me want to laugh to hide my tears. You may be referring to the fact that volcanoes emit lots of HCl which is by no stretch of the imagination a CFC, but that aside HCl being water soluble is very quickly taken up into the drops of water which form as the huge quantities of steam which a volcano also emits cool and coalesce. This is called rain out and is why most HCl emitted by volcanoes spends about 25min in the atmosphere.There are some reports of natural CFC's by not-REAL scientists. For example it looks like some CFC's are produced by volcanoes but in amounts so small we never noticed before (we measure annual atmospheric concentration increases and only need to include anthropogenic sources to model the increases), also some bugs which live in the ocean emit methyl chloride and methyl bromide which can almost be called CFC's but these are not long enough lived to diffuse to the stratosphere without being degraded in to water soluble forms which are rained out quickly. So Mr. eco-doodo I call your bluff who are the REAL scientists you refer to, where do they work, where do they publish, and who funds them? Inquiring minds want to know. Finally I am sorry about your A/C and I am against the proposed ban on all chloride containing compounds (table salt?) and I know that some environmental types tend to fight with their hearts but please please turn off the Rush and go down to the library (please? why dontcha?). Until you do don't talk to me about misinformation.
