The rich are adept at tax avoidance, and as tax rates climb, they spend a growing proportion of their energy avoiding taxes, instead of finding productive places to employ their capital. No, high taxes don't punish the rich; they punish would-be entrepreneurs in need of that capital.

Entrepreneurs with money ARE the wealth-creating engine of society. Without them, the economy would stagnate; THEN all we'd have to talk about is how best to redistribute a fixed (...no wait, a SHRINKING) pie. Entrepreneurs and capital would flee to better opportunities overseas. So, since you don't "worship" at the entrepreneur's altar, which altar DO you worship at?

The original theories of Rowland and Molina had absolutely nothing to do with Antarctic ozone depletion, and were found later to predict nothing of any consequence. However, the observation of the ozone "hole" was immediately pounced upon as proof of the original predictions, and CFCs were implicated long before adequate models had been developed which fully explained the observation. That is not to say subsequent work by Rowland was not brilliant or inappropriate.

Prior to CFCs there was sufficient Cl in the stratosphere to cause ozone depletion. That CFCs etc have an effect is not in question. What I am suggesting is that the ozone hole has always been there, and that CFCs are enhancing a natural phenomenon, rather than being the sole cause. And you are in no position to lecture me on my education, Doug. Your ozone page does not display any real knowledge on your part re ozone depletion.

What you don't seem to understand is that none of the material you think proves me wrong, actually addresses the issues which I am raising: That ozone depletion is a natural phenomenon. That there is no evidence of biological harm from ozone loss. That the Montreal Protocol addresses the issue appropriately. Now, I have posted a suitably referenced article on these issues (it follows). If you wish to discuss this matter further, I strongly recommend that you address each of these issues, with adequate references drawn from your links. Otherwise you identify yourself as one of those "dittohead parrots" you despise. ----------------- 1. Ozone depletion is a natural phenomenon. The chemistry involved in polar stratospheric ozone depletion has been well researched and is described in a number of excellent publications. The following description of the ozone depletion chemistry is derived from Parson's Ozone FAQ at http://www.cis.ohio-state.edu /hypertext/faq/usenet/ozone-depletion/antarctic/faq-doc-12.html. Briefly, ozone depletion results from the reaction of inorganic chlorine compounds (HCl, ClONO2) on the surface of polar stratospheric clouds PSCs.The inorganic Cl compounds arise from the photolysis of organic compounds which rise to the stratosphere by eddy diffusion. These organochlorides include methyl chloride (natural) and CFCs. PSCs are crystals of nitrogen compounds (eg nitric acid) and water. They occur at -80 deg C. PSCs do not occur at greater than this temperature. During winter, inorganic Cl compounds HCl and ClONO2 react with the PSCs to form large amounts of ClO. When the sun returns in spring, the ClO reacts rapidly as follows: ClO + ClO -> ClOOCl ClOOCl + hv -> Cl + ClOO ClOO -> Cl + O2 2 Cl + 2 O3 -> 2 ClO + 2 O2 ^^^^ In recent times ozone Antarctic ozone depletion has been measured to increase each year. This correlates with the increased abundance of inorganic Cl due to the increase of man-made CFCs. However there are a number of anomalies which cast doubt on the idea that this is the sole cause of the so-callesd ozone hole. (1) Ozone depletion also correlates very strongly with PSC concentration. For example consider the correlation between observed temperature rise, and decrease in observed ozone depletion in 1988. [Shanklin]. In that case, reduced PSCs due to relatively high temperatures resulted in a dramatic decline in ozone depletion rates. Since inorganic Cl compounds and PSCs occur naturally, and 1993 UARS measurements and studies of Arctic ozone depletion [Waters et al] [Gleason et al] show that PSCs are critical in the reaction, the entire observation of Antarctic ozone depletion can be logically expained by natural mechanisms involving cyclical stratospheric temperature variations. (2) There has always been a relatively large burden of inorganic Cl present. Since direct measurement of the gaseous composition of the stratospherehas been occurring only for the last 20 or so years, proof by direct measurement of the natural state is not possible, and all discussion on this subject is of course speculative. However HCl was first measured in 1976 [Farmer et al.] [Eyre and Roscoe].It is now well known that in the stratosphere the HCl mixing ratio increases with altitude, rapidly up to about 35 km, and then more slowly up to 55km and beyond. Also it is known that the mixing ratios of naturally occurring CH3Cl shows a rapid decrease with altitude in the stratosphere. The turnover in organic chlorine correlates nicely with the increase in inorganic chlorine. This suggests that CH3Cl may be being photolyzed as it rises high enough in the stratosphere to experience enough short-wavelength UV. [Fabian et al. ] [Zander et al. 1987] [Zander et al. 1992] [Penkett et al.] Methyl chloride (CH3Cl) comes mostly from natural (biological) sources, and is estimated to pass from the troposphere to the stratosphere at the rate of about 1 Mt/year. It is reasonable to assume that this flux has been occurring, at least at this rate, for about a billion years. Whilst there are well known natural sources of organic and inorganic chlorine, and proven mechanisms for the transportation to the stratosphere, there are no demonstrable mechanisms for the removal of HCl from the stratosphere. The argument that a drop off of HCl with altitude in the troposphere is evidence of a low natural upward flux, may also be applied to the stratosphere in reverse. [From Parsons FAQ, Copyright 1995] "...the mixing ratio of HCl _decreases_ with altitude in the troposphere, reaching vanishingly small values at the tropopause, and then _increases_ with altitude in the stratosphere. This rules out all processes in which HCl slowly drifts upward from the troposphere." This also implies that there is no downward drift either. Therefore, if there is no significant sink for HCl in the stratosphere, then a low flux over millenia of volcanic and biological activity will produce a large natural burden of inorgnic chlorine reservoir compounds in the stratosphere, at least as significant as the natural tropospheric burden. Consider that mixing ratio measurements for HCl from Kitt Peak go from 1.6e15 molecules/cm^2 in 1977 to ~2.6e15 molecules/cm^2 in 1990. The source for this is Rinland et al., J. Geophys. Res. _96_, 15523, 20 Aug 1991 (with thanks to Robert Parsons). I assume these figures are for stratospheric HCl only. Assuming the above figures to be correct, then I calculate: HCl Mixing ratio = 2.6e15 molecules/cm^2 in 1990 Area of earth = 510E6km^2 = 5.1E18cm^2 No. molecules HCl = 1.326E34 molecules No. moles HCl = 1.326E34/6.02E23 = 2.2E10 moles Mass of HCl = 2.2E10 * 36 grams/mole = 7.9E11 g = 790 kt Assuming that the increase is entirely from CFCs (ie avoiding the volcano debate), the contribution from CFCs is about 23kt /year or less than 3% of total Cl from CFC flux (~1-2Mt/year). Also calculating the mass of HCl in 1977 and extrapolating backwards, the natural burden of HCl is about 450 kt. Therefore inorganic Cl compound flux from CFCs is small compared to the natural burden of HCl in the stratosphere. BTW the contribution from natural sources -photolysing of methyl chloride and perhaps (gasp) volcanos - is about 1/4 of that from CFCs [WMO 1991] [Solomon] [AASE] [Rowland 1989,1991] [Wayne], or about 500 t/year. This is the mechanism for generating the 450kt natural burden. One observation which suggests a natural burden of inorganic Cl follows: Measurements in the Chappuis ozone absorption band by the Astrophysical Observatory of the Smithsonian Institution at Mount Wilson, California, in 1912 were studied by Gotz and others, who reported on the ozone decline in various publications. Katmai erupted when inorganic chlorine from anthropogenic sources was probably at negligible levels. Courtesy Forrest M. Mims III, Sun Photometer Atmospheric Network (SPAN) Also from Parson - Copyright 1995: "The total amount of HF in the stratosphere increased by a factor of 3-4 between 1978 and 1989 [Zander et al., 1990] [Rinsland et al.]; the relative increase is larger for HF than for HCl (a factor of 2.2 over the same period) because the natural source, and hence the baseline concentration, is much smaller." Translation: there is much more natural stratospheric HCl than HF arising from anthropogenic sources. The only evidence against the notion of a large natural burden of inorganic Cl compounds is that Dobson, as quoted in his book Exploring the Atmosphere failed to measure a significant drop in ozone in his initial observations during the 50s and 60s. The reasoning is that since PSCs are naturally ubiquitous (and ASSUMED a constant factor) then no observed ozone depletion means no stratospheric Cl compounds. It is worth noting that one of Dobson's co-workers, Marcel Nicolet, admitted in a TV interview, that during the 50s and 60s, anomalous readings below 250 DU were not officially recorded because, said Dobson: "Noone will believe them". (ref: Interview on Belgian TV "Fair skin, stay in." Sept 18, 1992). ----------------------------------------------------------------------- 2. Ozone depletion causes no biological damage. Ozone depletion at the poles results in insignificant UV increase, because the sun is so low on the horizon. Also the area affected is almost entirely devoid of life larger than microbes. At mid-latitudes increase in UV due to ozone depletion is very low compared to daily, seasonal and global variations. This is due to an absence of PSCs (at mid-latitudes) and so ozone depletion only takes place there in the presence of sulphate aerosols from volcanic activity (which is natural). In urban areas of the US, UV-B levels showed no significant increase (and in most cases actually decreased a little) between 1974 and 1985. [Scotto et al.]. This is probably due to increasing urban pollution, including low-level ozone and aerosols. [Grant] [from Parsons FAQ, Copyright 1995] Several studies [Kerr and McElroy] [Mims] [Seckmayer et al.] [Zerefos et al.] have presented evidence of short-term UV-B increases at middle latitudes associated with the record low ozone levels in 1992-93. As discussed in Part I, these low ozone levels are probably due to stratospheric sulfate aerosols from the 1991 eruption of Mt.Pinatubo; Studies done prior to the Mt Pinatubo eruption show no more than a correlation with the flow of ozone poor polar air during the summertime breakdown of the polar vorticies. At most the effects are only a few percent, which is insignificant relative to daily, seasonal and global variations. There is also considerable evidence which supports the assertion that fatal melanomas are related to UV-A and natural light (and not UV-B). This means that it is not possible to correlate ozone depletion with human fatality. [Balliunas] Considering the fact that UV levels have not risen significantly in populated areas and that it is unlikely that small increases in UV-B will have negative effects anyway, it is difficult formulate a testable hypothesis, let alone devise a test to prove that ozone depletion causes biological harm. ----------------------------------------------------------------------- 3. The Montreal Protocol is expensive, and ineffective in curbing ozone depletion. From MONTREAL PROTOCOL ON SUBSTANCES THAT DEPLETE THE OZONE LAYER LONDON, 27-29 JUNE 1990 ARTICLE 5: SPECIAL SITUATION OF DEVELOPING COUNTRIES18 1. Any Party that is a developing country and whose annual calculated level of consumption of the controlled substances in Annex A is less than 0.3 kilograms per capita on the date of the entry into force of the Protocol for it, or any time thereafter [within ten years of the date of entry into force of the Protocol] until 1 January 1999, shall, in order to meet its basic domestic needs, be entitled to delay for ten years its compliance with the control measures set out in Articles 2A to 2E [...] That is over 100 Mt of CFCs, which developing countries may release into the atmosphere, which is far more than the 1990 annual rate for developing countries. What's more, further restrictions are based on the funding of technology transfers from developed to developing countries, a hidden cost in the abolition of CFCs for countries like Australia. Also China, Japan, Indonesia and Korea are not party to the Montreal Protocol, while developed countries (which are party to the MP) like Australia are obliged, according to the Montreal Protocol, to pay for the changes in infrastructure in developing countries. Not only is the MP an ineffective solution, but it is expensive. ----------------------------------------------------------------------- References: Robert Parsons Ozone FAQ Copyright 1995.

But I don't think you can say the opposite either. I think what I would claim is that what they say in their Consequences article is (at best) open to misinterpretation. Examples of such misinterpretation (at best) appear in two New York Times articles in January of this year. On 1/8/96 ("The Blizzard of 1996: The Cause: Deep Jet-stream Shifts make the blizzard possible" by William K. Stevevns, Sec 1, p31) the New York Times wrote in part: "Government scientists say they have found more precipitation is falling in extremely heavy one-day events than was true 20 years ago, and they are 90 to 95 percent sure that the change has resulted from the effects of the heat-trapping gases released by the burning of fossil fuels like coal and oil." and on 1/14/96 ("Ideals & Trends; Blame Global Warming for the Blizzard" by William K. Stevens, Sec 4, p. 4) the New York Times wrote in part: "By comparing this pattern with the pattern of climate change that computer simulations indicate should result from an increase in heat-trapping 'greenhouse' gases like carbon dioxide, the analysts concluded that there is a 90 to 95 percent chance that the increase in extremes was caused by the increase in greenhouse gases." Both articles quote Thomas R. Karl of the National Climate Data Center in Asheville, N.C. Of course it is possible the New York Times got it wrong. On the other hand perhaps the Times reporter is accurately reporting what he was told by Karl. Btw the second article also states: "... Mr Karl has not been known as a doom-sayer on the question of global warming." I wonder what the source for this was. James B. ShearerReturn to Top

This can be clearly demonstrated by the fact that certain inputs lead to outputs that make sense. However, how do we know that the output of the present models accurately predicts the correct temperature gain for a given amount of CO2 (or methane, or any other disturbance you care to name) that is injected into the atmosphere? Just because a correct heat and material balance is done does not mean that all constraints are properly modelled, or that all feedback loops are correct or even identified. I've beat this dead horse way too much in the past. If you don't get physical data that verifies your predictions, you have no way of knowing if the models are correct. If you don't know if the models are correct, you have no business using them to set policy. If you want a change that has such political overtones, you are wasting your time trying to justify it with science in the first place.Return to Top

I don't consider concerns about our nuclear plants "wild eyed froth", and obviously neither does the AECB when there are such serious concerns about even renewing operating licences at some plants. It's a matter of what you consider "acceptable risk", and your tolerence may be higher than others (mine included). >I'm not hostile to wind power as such.

I find this rather aggravating. People make I don't think anyone is proposing an out and out complete replacement of our generating capacity with wind power, and at this stage is not suggesting 1200MW wind plants. Ontario Hydro uses a mixture of nuclear, thermal, and hydro generation, at many different installed capacities, and 'system' utilizes each for maximum effectivness (ever tried to run a reactor as a "peaking producer"?) Take a trip to system control and learn a little more about the actual generation and utilization of power for "the grid". >I'm not hostile to environmental concerns as such.

Not all "large scale" is good, and Hydro uses many small hydraulics wherever feasable, the same can be done for alternative energy sources. Hydro is far, far too stuck with large installed capacity, but it IS a great place for NUG's to work (Non-Utility Generation for non-hydroids). Private producers could have a good shot at it if REAL generation costs were in the picture. > Occasionally >flocks of starlings will pass over in sight of my apartment >building.

Every form of electrical generation has it's impacts. Hydraulics flood massive areas of land, and impact aquatic life. Fossil fueled plants produce airborne emissions, and thermal polution. Nukes produce thermal polution, and they STILL haven't figured out what to do with your waste, cause it IS so dangerous. >Numbers guy. We need numbers backed by experiment and >demonstration sites to be able to evaluate wind generation. That's what this discussion is about. All forms of generation we use now have had decades or centuries of research and experimentation to bring them to the level of technology they are at today. Wind, solar, wave, etc are in their infancy in comparison. No need to jump on top of some free-thinkers just for expressing ideas. K. JonesReturn to Top
* Environmental Quotes * Daily... "The air is fragrant with summer- swamp scent - a blend of mud, algae, soapflower, and buttonbush. All around us is the sleepy music of summer swamp - the rattle of a kingfisher, the chucking of the now mostly quiet red-winged blackbirds, the banjo twang of green frogs, the buzz of cicadas starting in one red maple and picking up in another. I learned a long time ago that one of the things swamps are good for is slowing summers that go by too fast. " - Ted Williams, "What Good Is a Wetland?", Nov-Dec.

My original comments hold. The question was whether or not this is something that could be left to the military, presumably the US Miltary. I still say that detection and deflection or break up of an object which might collide with the Earth and prduce great damage is something which by its very nature requires international cooperation. It is not basically a military problem, and while military technology could be involved in dealing with a threat, thinking of it that way is a mistake. Militaries exist to either deter or to fight wars with foreign human enemies, not to deflect asteroids. -- Leonard Evens len@math.nwu.edu 491-5537 Department of Mathematics, Norwthwestern University Evanston IllinoisReturn to Top

Shearer I believe this has also been reported in Nature or Science. There is no real way to know why science reporters think this without asking them. I would conjecture that they asked around among climatologists they know and that is what they have been told. Since this is not really a scientific statement but rather a statement about a science, I imagine ordinary journalistic standards apply. While Stevens might have misunderstood some of Karl's science, I doubt if he could have got something like this entirely wrong, but of course I could be wrong. In any case, Karl has a very extensive publication record and is an established authority in observational climatology. One can judge his biases by studying his publications in some detail. -- Leonard Evens len@math.nwu.edu 491-5537 Department of Mathematics, Norwthwestern University Evanston IllinoisReturn to Top
Had Shoemaker-Levy been headed toward the earth when detected near Jupiter, a delta v of 1/4 meter/sec would have sufficed (at that time) to prevent it from hitting the earth. A few hundred kilotons of energy would have done it. Given inefficiencies, a few megatons of nuclear explosive would have sufficed. However, we couldn't have gotten the explosives to the comet right away. Maybe an emergency effort could have met it half way. In this case the energy requirement would be multiplied by 4. This assumes that the nuclear explosion was at a distance and the energy delivered in the form of x-rays that would vaporize the nearest 20 cm of surface of the comet, giving the comet as a whole a gentle push. If the comet were already broken up there would be complications. Any such emergency action would have a substantial chance to not work. The astronomers I asked all said that there was no chance that Shoemaker-Levy would head for the earth because it was too closely bound to Jupiter's orbit. There was a discussion of all this in _Nature_ a few years ago. -- John McCarthy, Computer Science Department, Stanford, CA 94305 http://www-formal.stanford.edu/jmc/progress/ During the last years of the Second Millenium, the Earthmen complained a lot.Return to Top
