Ian Rutherford Plimer (born 12 February 1946) is an Australian geologist,
academic and businessman, and professor of mining geology at the University
of Adelaide . You will appreciate his take on climate change
(aka: global warming).
Professor Ian Plimer could not have said it better! If you've read his book
you will agree, this is a good summary.
Are you sitting down?
Okay, here's the bombshell. The volcanic eruption in Iceland , since its
first spewing of volcanic ash has, in just FOUR DAYS, NEGATED EVERY SINGLE
EFFORT you have made in the past five years to control CO2 emissions on our
planet - all of you.
Of course you know about this evil carbon dioxide that we are trying to
suppress - it's that vital chemical compound that every plant requires to
live and grow, and to synthesize into oxygen for us humans, and all animal
life.
I know, it's very disheartening to realize that all of the carbon emission
savings you have accomplished while suffering the inconvenience and expense
of: driving Prius hybrids, buying fabric grocery bags, sitting up till
midnight to finish your kid's "The Green Revolution" science project,
throwing out all of your non-green cleaning supplies, using only two squares
of toilet paper, putting a brick in your toilet tank reservoir, selling your
SUV and speedboat, vacationing at home instead of abroad, nearly getting hit
every day on your bicycle, replacing all of your 50 cents light bulbs with
$10.00 light bulbs . . . well, all of those things you have done have all
gone down the tubes in just four days.
The volcanic ash emitted into the Earth's atmosphere in just four days - yes
- FOUR DAYS ONLY by that volcano in Iceland , has totally erased every single
effort you have made to reduce the evil beast, carbon. And there are around
200 active volcanoes on the planet spewing out this crud any one time -
EVERY DAY.
I don't really want to rain on your parade too much, but I should mention
that when the volcano Mt Pinatubo erupted in the Philippines in 1991, it
spewed out more greenhouse gases into the atmosphere than the entire human
race had emitted in its entire YEARS on earth. Yes folks, Mt Pinatubo was
active for over one year - think about it.
Of course I shouldn't spoil this touchy-feely tree-hugging moment and
mention the effect of solar and cosmic activity and the well-recognized
800-year global heating and cooling cycle, which keep happening, despite our
completely insignificant efforts to affect climate change.
And I do wish I had a silver lining to this volcanic ash cloud but the fact
of the matter is that the bush fire season across the western USA and
Australia this year alone will negate your efforts to reduce carbon in our
world for the next two to three years. And it happens every year.
Just remember that your government just tried to impose a whopping carbon
tax on you on the basis of the bogus "human-caused" climate change scenario.
Hey, isn't it interesting how they don't mention "Global Warming" any more,
but just "Climate Change" - you know why? It's because the planet has COOLED
by 0.7 degrees in the past century and these global warming bull artists got
caught with their pants down.
And just keep in mind that you might yet have an Emissions Trading Scheme -
that whopping new tax - imposed on you, that will achieve absolutely nothing
except make you poorer. It won't stop any volcanoes from erupting, that's
for sure.
But hey, relax, give the world a hug and have a nice day!
PS: I wonder if Iceland is buying carbon offsets?

Spontaneous Remission and the Placebo Effect
I had fully intended to write a piece today on spontaneous remission and how it influences treatments and results that people choose.
I had, recently, an occasion to be privately messaged by a peddlar of a wieght loss MLM product line to inform me that my information regarding a particular product that appeared in her blog could potentially damage her efforts to sell the multi thousand dollar remedies.
I have to take exception to putting sales before health and wonder how some can sleep at night.
My research to date suggests that the product line leaves much to be desired from the persective of science and the effectivenes of it's main ingredients but that is for another blog.
I found this page while googling and it mirrors what I was about to discuss regarding the association in the mind between cures and disease.

Spontaneous Remission and the Placebo Effect
Stephen Barrett, M.D.
When someone feels better after using a product or procedure, it is natural to credit whatever was done. However, this is unwise. Most ailments are self-limiting, and even incurable conditions can have sufficient day-to-day variation to enable quack methods to gain large followings. Taking action often produces temporary relief of symptoms (a placebo effect). In addition, many products and services exert physical or psychologic effects that users misinterpret as evidence that their problem is being cured. These "Dr. Feelgood" modalities include pharmacologically active herbal products, quack formulas adulterated with prescription drugs, colonic irrigations (which some people enjoy), bodywork, and meditation. Scientific experimentation is almost always necessary to establish whether health methods are really effective. Thus it is extremely important for consumers to understand the concepts of spontaneous remission and the placebo effect.
Spontaneous Remission
Recovery from illness, whether it follows self-medication, treatment by a scientific practitioner, or treatment by an unscientific practitioner, may lead individuals to conclude that the treatment received was the cause of the return to good health. As noted by Medical historian James Harvey Young, Ph.D.:
John Doe does not usually realize that most ailments are self-limiting and improve with time regardless of treatment. When a symptom goes away after he doses himself with a remedy, he is likely to credit the remedy with curing him. He does not realize that he would have gotten better just as quickly if he had done nothing! Thousands of well-meaning John and Jane Does have boosted the fame of folk remedies and have signed sincere testimonials for patent medicines, crediting them instead of the body's recuperative power for a return to well-being. . . .
The unscientific healer does not need to observe the restraints of reputable medicine. Where true medical science is complex, the quack can oversimplify. . . . Where ailments are self-limiting, the quack makes nature his secret ally [1].
It is commonly said that if you treat a cold it will disappear in a week, but if you leave it alone it will last for seven days. Even many serious diseases have ups and downs. Rheumatoid arthritis and multiple sclerosis are prime examples. On rare occasions, even cancer can inexplicably disappear (although most testimonials for quack cancer remedies are based on faulty original diagnosis or simultaneous administration of effective treatment).
Quackery's victims are not the only ones who can be fooled by the placebo effect, spontaneous remissions, and other coincidental events. The gratitude and adulation of people who think they have been helped can even persuade charlatans that their methods are effective!
The Placebo Effect
The power of suggestion has been demonstrated by many investigators in a variety of settings. In a classroom, for example, a professor sprayed plain water about the room and asked the students to raise their hands as soon as they detected an odor. Seventy-three percent managed to smell a nonexistent odor.
Persons with a dominant or persuasive personality often have considerable impact on others through their ability to create confidence, which enhances suggestibility. Many individuals who are taken in by a charlatan later tell their doctors, "But he talked to me; he explained things; he was so nice."
Individuals who are psychologically susceptible to suggestion often feel better under the influence of counseling or reassurance. Several years ago, an airline flight attendant told me, "I take a multivitamin pill that Consumer Reports says is useless. But I don't care. It makes me happy."
Gullibility and wishful thinking are common human characteristics. People are willing to believe in untrue things in varying ways and to varying degrees. Even scientifically sophisticated people may respond to the power of suggestion.
In medicine the effect of suggestion is referred to as the "placebo effect." The Latin word placebo means "I shall please." A placebo effect is a beneficial response to a substance, device, or procedure that cannot be accounted for on the basis of pharmacologic or other direct physical action. Feeling better when the physician walks into the room is a common example.
A placebo may be used in medicine to satisfy a patient that something is being done. By lessening anxiety, placebo action may alleviate symptoms caused by the body's reaction to tension (psychosomatic symptoms). In certain circumstances, a lactose tablet (sugar pill) may relieve not only anxiety but also pain, nausea, vomiting, palpitations, shortness of breath, and other symptoms. The patient expects the "medication" to cause improvement, and sometimes it does.
Many studies suggest that placebos can relieve a broad range of symptoms. In many disorders, one third or more of patients will get relief from a placebo. Temporary relief has been demonstrated, for example, in arthritis, hay fever, headache, cough, high blood pressure, premenstrual tension, peptic ulcer, and even cancer. The psychologic aspects of many disorders also work to the healer's advantage. A large percentage of symptoms either have a psychologic component or do not arise from organic disease. Hence, treatment offering some lessening of tension can often help. A sympathetic ear or reassurance that no serious disease is involved may prove therapeutic by itself. Psychologist Barry Beyerstein, Ph.D., has observed:
Pain is partly a sensation . . . and partly an emotion. . . . Anything that can allay anxiety, redirect attention, reduce arousal, foster a sense of control, or lead to . . . reinterpretation of symptoms can alleviate the agony component of pain. Modern pain clinics put these strategies to use every day. Successful quacks and faith healers typically have charismatic personalities that make them adept at influencing these psychological variables that can modulate pain. . . . But we must be careful that purely symptomatic relief does not divert people from proven remedies until it is too late for them to be effective [2].
Confidence in the treatment -- on the part of the patient and the practitioner -- makes it more likely that a placebo effect will occur. But the power of suggestion may cause even a nonbeliever to respond favorably. The only requirement for a placebo effect is the awareness that something has been done. It is not possible to predict accurately or easily a particular patient's reaction to a placebo at a particular moment. However, the psychologic predisposition to respond positively to placebos is present to some extent in most people. Some are very likely to obtain relief from placebos in a wide variety of situations, whereas others are very unlikely to do so. Most people's response lies somewhere inbetween.
Another factor that can mislead people is selective affirmation -- a tendency to look for positive responses when improvement is expected. As former National Council Aghainst Health Fraud president William T. Jarvis, Ph.D., has noted:
A culturally significant setting can also produce a potent effect, as folk healers know well. Effective settings can be as divergent as the trappings of an oriental herb shop to Asians, a circle of witchcraft paraphernalia to a primitive tribesman, or the atmosphere of a modern clinic to a modern urban American. Social expectations can also play a role, as occurs in stoic cultures where people are taught to endure pain and suffering without complaining. . . .
Operant conditioning can occur . . . when behavior is rewarded. . . . Thus, people with a history of favorable responses to treatment are more apt to react well to the act of treatment [3].
Moreover, says Dr. Jarvis:
People suffering from chronic symptoms are often depressed, and depression often produces symptoms that the patient attributes to the underlying disease. If the quack's promises make the patient feel hopeful, the depressive symptoms may resolve, leading the patient to conclude -- at least temporarily -- that the quack's approach has been effective against the disease [4].
Responses to the treatment setting can also be negative ("nocebo effects"). In one experiment, for example, some subjects who were warned of possible side effects of a drug were given injections of a placebo instead. Many of them reported dizziness, nausea, vomiting, and even mental depression. A recent review of 109 double-blind drug trials found that the overall incidence of adverse events in healthy volunteers during placebo administration was 19% [5].
Placebo responses, such as feeling less pain or more energy, do not affect the actual course of the disease. Thus placebo responses can obscure real disease, which can lead to delay in obtaining appropriate diagnosis or treatment.
The placebo effect is not limited to drugs but may also result from procedures [6]. Devices and physical techniques often have a significant psychologic impact. Chiropractors, naturopaths, and various other nonmedical practitioners use heat, light, diathermy, hydrotherapy, manipulation, massage, and a variety of gadgets. In addition to any physiologic effects, their use can exert a psychologic force that may be reinforced by the relationship between the patient and the practitioner. Of course, devices and procedures used by scientific practitioners can also have placebo effects.
Ethical Considerations
Doctors are confronted by many people who complain of tiredness or a variety of vague symptoms that are reactions to nervous tension. Far too often, instead of finding out what is bothering them, doctors tell them to take a tonic, a vitamin, or some other type of placebo.
A recent study has challenged the widely held view that the placebo effect is a major factor in the outcome of clinical trials. Most placebo-controlled trials compare the active treatment with a placebo, not with no treatment. This design cannot distinguish an effect of placebo from the natural course of the disease, regression to the mean (the tendency for random increases or decreases to be followed by observations closer to the average), or the effects of other factors. After analyzing 114 randomized trials that had a "no-treatment" group in addition to active treatment and placebo groups, the authors concluded:
Placebos appeared to produce modest benefit in studies of pain and in other studies where the outcome being measured was similarly subjective.
Some of the reported benefit may be the result of placebos may be the result of patients wishing to please their doctors.
There is no justifiable placebo use outside of clinical trials [7].
An accompanying editorial stated that placebo use should be sharply reduced but may still be justified in carefully selected situations where pain relief is needed [8]. The study also casts doubt on the widely promoted notion that "alternative methods" may work by stimulating a placebo effect
Quacks who rely on the placebo effect pretend that (a) they know what they are doing, (b) they can tell what is wrong with you, and (c) their treatment is effective for just about everything. Many of their patients play the equivalent of Russian roulette. Medical doctors who use vitamins as placebos may not be as dangerous, but they encourage people to habitually use products they don't need. Because most people who use placebos do not get relief from them, their use is also a financial rip-off.

Arguing just to win is counter productive
http://dumbscientist.com/archives/people-who-argue-to-win-annoy-me
Posted December 1st, 2008 in Philosophy. Tags: Introductory-Phil., No Equations, Quickie.
I enjoy civilized debates, but I rarely get the chance to engage in them. That’s because in my experience nearly everyone assumes they’re correct, so they only debate to beat their viewpoint into the other person’s head at all costs.
In other words, most people argue to win… and I can’t stand it. Whenever I mention this pet peeve, the response is almost always “Oh, so you argue to lose, huh?”
Not exactly. I see a third alternative, one that seems more productive. I argue to learn.
In fact, I think the best possible outcome of a debate is when my opponent convinces me that he’s right and I’m wrong. That way, I’ve learned something new or improved my worldview by fixing a mistake. It’s just boring to convince someone else that I’m right. What do I gain from a debate that I “win” in that manner? Very little, I think.
That’s the point of this website. I’ve decided that I can no longer develop my ideas in isolation. I’m blind to the flaws in my own ideas because I’m simply too biased towards believing they’re true.
It might seem like I shouldn’t be annoyed with people who argue to win, because they’re doing me a favor by enthusiastically attacking my ideas. While it’s true that I desperately want people to attack my ideas in order to identify flaws in my reasoning, the problem is that people who argue to win generally aren’t very persuasive. They’re certainly motivated to attack my ideas (which I appreciate), but the resulting arguments have always been much less enlightening than conversations with people who disagree with me in a calm, non-confrontational manner.
That’s because you have to understand another person’s position at least a little bit before you criticize it. Otherwise your attacks might not be aimed at their central point, or you may misinterpret their position altogether. Your arguments must also serve as a “bridge” between the other person’s position and your own, to show the other person how to cross the intellectual distance that separates your positions. Finally, you can’t simply grab the first argument that appears to support your position or attack your opponent’s. This happens most often in verbal debates where there isn’t much time for research or introspection between intellectual salvos. But it also occurs in written debates with depressing frequency, and the resulting arguments simply aren’t challenging enough.
For me, debating means to seriously entertain my opponent’s viewpoint, to examine the world through the lens of his assumptions. If I happen to like his viewpoint better than mine (which happens occasionally) I cheerfully say “thank you for correcting me” and drop my old position like the proverbial hot potato. I’m not on anyone’s side but my own, and sometimes I’m not even on my own side…

Benefits of Buying Local Can Be a Far-Off Fantasy
This information seems to provide more "food for thought" about different approaches to sustainabilty.
There's some pretty outrageous assumptions out there coming from the misinformed.
There must be a decent balance that preseves the environment without impacting the lives of our neighbours.

Organic Food Miles Take Toll On Environment
http://www.sciencedaily.com/releases/2007/06/070606113311.htm
ScienceDaily (June 7, 2007) — Organic fruit and vegetables may be healthier for the dinner table, but not necessarily for the environment, a University of Alberta study shows.
--------------------------------------------------------------------------------
The study, conducted by a team of student researchers in the Department of Rural Economy at the University of Alberta in Edmonton, Canada, showed that the greenhouse gas emitted when the produce is transported from great distances mitigates the environmental benefits of growing the food organically.
"If you're buying 'green', you should consider the distance the food travels. If it's travelling further, then some of the benefits of organic crops are cancelled out by extra environmental costs," said researcher Vicki Burtt.
Burtt and her fellow researchers compared the cost of 'food miles' between organic and conventionally grown produce, and found that there was little difference in the cost to the environment.
Food miles are defined as the distance that food travels from the field to the grocery store. The study found that the environmental cost of greenhouse gas (CO2) emitted to transport 20 tonnes of organically grown produce was comparable to that of bringing the same amount of conventional fruit and vegetables to market.
For the study, the team collected retail price data from six grocery stores and interviewed suppliers about their shipping methods. They created comparable food baskets of both organic and conventionally-grown fruit and vegetables being transported to Edmonton stores by truck, train or ship, and found that most travels by truck. Since 1970 truck shipping has increased, replacing more energy-efficient rail and water transport.
The researchers calculated that the annual environmental costs for a city the size of Edmonton were $135,000 to $183,000 (5,492-7,426 tonnes CO2) for conventional produce and $156,000 to $175,000 (6,348-7,124 tonnes CO2) for organic produce. Many of the organic products are travelling further than the conventional food. Two items in particular, mangoes and green peppers, were shipped much further than their conventional counterparts (4,217 and 1,476 kilometres, respectively). The mangoes were shipped from Ecuador and Peru as opposed to Mexico, and the peppers came from Mexico as opposed to Canada or the United States.
To help reduce greenhouse gases, Burtt recommends that shoppers switch to buying locally produced food at grocery stores or farmers' markets when possible, and that any future government policy on the environment should consider the reduction of CO2 emissions associated with food transport. The study also found that a large gap between total costs to the consumer and the price paid in the store for organic produce indicates that retailers could cover the environmental costs without passing those costs on to the consumer.
