It was also the concensus view that this critter, and those like him, died out because they "got too big." No. That's a cute story, but fantasy. Although there were much speculation as to what might have caused the extinctions, there was certainly no consensus on the topic. To quote the Encyclopedia Britannica from 1973: "What caused this sudden extinction? The answer is not at all clear. Temperature changes, epidemics, eating of dinosaur eggs by early mammals, have all been suggested but are far from satisfactory." Perhaps in your school system the teachers made up fairy tales; that could explain a lot. The Denver Public School System, in the 60's, was rated very highly. And regardless what the Encyclopedia Britannica would say in the next decade, the story I related was accurate. I was at the local library today and wandered over to the "Dinosaur" section. The books there were labeled with the publication date on the spine, so it was easy to find the several books from the late '50's through the '60's. For completeness, I also went up to the "old reference" section and found an encyclopedia from 1967. Without exception, they had the same information as the 1973 Britannica. For example, "The Fossil Book," 1958, went on for several pages in a section titled "The Puzzle of Extinction" with a discussion of the various theories. They favored climate change triggered by some unknown cause, but noted that no one had presented any complete theory that fit the data. Without exception, every text presented this as a mystery that maybe someday will be solved. This is how I remember the subject being presented here in Boston, but secretly I favored the egg-sucking mammal theory. So the question now is, was the Denver School System incompetent back then, or is KLC spinning a cute yarn? Now you're just being insulting. Perhaps the teachers back then, rather relying upon the most recent data, repeated what they had been told when *they* were in school. How many elementary school teachers do you know who are rocket scientists? The fact remains that the critter was called "Brontosaurus" at least until 1974, we were taught that he dragged his tail, and we were taught that they died out from "Gigantism." You can apply today's theories and knowledge to the past as much as you would like, but I attended public school in three states (Colorado, New York, New Jersey), and distinctly remember being taught pretty much the same thing in all of them. Were they wrong? Yup. That's my point, innit? As for Gigantism killing the dinosaurs, the theory is making a comeback -- at least in some circles: http://www.dinoextinct.com/ . Will you now claim that this website doesn't exist? |

There were many hypotheses for the extinction, but virtually no proof for any of them. There is nothing wrong with presenting the various suggested possibilities, that's exactly what the my teachers did, and what the books of the day taught. Selecting one of them, and teaching it as accepted fact, as you claim your teachers did, is, at best, incompetence. |

My problem with your story is the implication is that society freely accepts theories that are later shown to be false. While there may be some cases of that, dinosaur extinction by gigantism is not one of them. Whether you were taught it, imagined it, or made it up yesterday is irrelevant. It was never accepted as probable by a significant number of scientists; it was just one of many hypotheses proposed to explain a mystery. |

As recently as 20 years ago, the medical community believed, and taught, that ulcers were caused by stress. Treatment for the condition was based upon that theory. It was universally accepted. It was nonetheless wrong. As recently as today, students are still being taught that Pluto is a planet, even though it is really only a "Kuyper Belt Object," and there are a significant number of *larger* Kuyper Belt Objects that have *never* been considered to be planets. Indeed, at least one Kuyper Belt Object (other than Pluto) has a moon, yet is still not a planet. So why are students still being taught outdated "facts"? What science considers to be truth today is what will be taught in schools for some time to come. Textbooks are not printed anew each time a new fact displaces an old fact -- nor can they be. So there will always be a lag between new discoveries and their acceptance by the general public -- for that matter, even by the experts in that particular field. And even then, there will always be the "old guard" who will cling steadfastly to what *they* learned when *they* were in school. Eventually, most -- if not all -- science textbooks will teach that Global Warming is caused by CO2 being pumped into the atmosphere by human activity. It may be taught as only a theory, but it will be accepted as fact, as the most current theories generally are. And by that time, it is highly likely that this theory, too, will be surplanted by another. |

* Cessna 310 wrote, On 4/5/2007 6:31 PM: After working with others for years developing ANSI and ISO standards, the meaning of consensus is fairly well understood. It basically means that though everyone may not agree with the final document, all the objections and negative votes have been addressed. The "final" standard is one that everyone can live with. Using this practical definition, there is no consensus agreement on whether or not man is the cause of global warming. That could be why this use of "consensus" is meaningless for scientific issues. For standards, everyone has already agreed to the concept that a 100% consensus that "everyone can live with" is more important than having a "perfect" standard. In the scientific world, a 100% consensus has no value, and in fact is undesirable. Scientists look for the truth, not some compromise that the most people can live with. The skeptics serve an important role in the process. In this world, the meaning of "consensus" is quite different. I also worked with ISO and, additionally, with self directed teams in organizations. The teams had in their charter that consensus would be the only means of arriving at a decision. The meaning of consensus in both of those arenas is just as described by Cessna 310. Multiply my experience by the number of other organizations that have been exposed to that and the population is large. Jeff, my only point is that for many people that is the meaning of consensus. If that group hears that word used in the case of GW, but knows that there are dissenters, then the credibility of those in the majority will be discounted. As you said, it is too important a matter to let that happen and there are better describers that will not cause that to happen. I'm not commenting on the reality of GW, the cause, and certainly not on any course of action with regard to it, just on being as clear as possible about what gets reported to the general public. Nor am I commenting on your opinion on the matter, since I don't actually know what it is. I'm as concerned as most about the probability of GW, and have taken more personal action in that regard than the Al Gore's, John Travoltas and others who seem to know what "we" should do, but are not willing to do themselves. Add them and others like them to what many "common folks" feel is a misues of the term "consensus" , and you get a discount of the issue that is not in anyone's best interest. And I do understand that in the dictionary, depending on which one and which version, majority is used as a definition in some order. My world book and MW have general agreement, unanimity as the first. But that's not the point. I refer to that population mentioned above that have had the meaning I hold true, drilled into them. They are not going to run to the dictionary, they will react to the use and possibly discount the message. Frank |

It was nonetheless wrong. Not entirely true, its still accepted that emotional stress can make the symptoms worse, and physical stress seems to trigger the ulcer infection. A large segment of the population is infected with the bacteria, but only a small number get ulcers - the reason for this is not understood. Also, it must be remembered that this breakthrough in treatment involves drugs that did not exist a few decades earlier, so reducing stress and modifying diet was not a bad treatment. You would do better to find cases where the traditional treatment was the complete opposite of what we believe to be true today. In the field of medicine, it should be easy to find dozens of such examples. As recently as today, students are still being taught that Pluto is a planet, even though it is really only a "Kuyper Belt Object," and there are a significant number of *larger* Kuyper Belt Objects that have *never* been considered to be planets. Indeed, at least one Kuyper Belt Object (other than Pluto) has a moon, yet is still not a planet. So why are students still being taught outdated "facts"? This issue is total bogus, as it has little to do with Pluto, but with the discovery of additional objects that caused astronomers to rethink the traditional classification system. In particular, the discovery of another roughly the size of Pluto meant that we had to decide between an ever-growing pantheon of planets, or 8 true planets, and a growing list of "dwarf" or "minor" planets. I remember being taught that Pluto was an "odd" planet, quite different from others. I also remember Fred Whipple, Al Cameron and others predicting that we might find numerous objects out there. Fred Leonard even speculated in 1930 that Pluto may be the first of a series of ultra-Neptunian bodies. It was just that we had to wait until 1992 to begin to discover the large number of objects. BTW, the term "Kuiper Belt" is somewhat controversial, since Kuiper had nothing to do with the discovery, and even claimed that it would unlikely to find much. The "Leonard-Whipple" belt would be more appropriate, but many favor "Trans-Neptunian Objects" (TNO's) or Minor Planets. What science considers to be truth today is what will be taught in schools for some time to come. Textbooks are not printed anew each time a new fact displaces an old fact -- nor can they be.

True, but it is sad that the common perception, reinforced by the popular press, often misses the true story. For example, the real story of Pluto is not that we lost a planet, but that we gained a whole category of minor planets. It is also sad that one book or movie that had little scientific foundation becomes remembered as the "consensus view." A perfect example of this is the book "The Cooling" which I happened to run into at the library yesterday. Dave mentioned in another thread that this was the "consensus view" in the 70's, but in fact it was a fringe view, not supported by any science. Even today, its poor interpretations of the contemporary science are repeated to show how science has "flip-flopped."

It is highly likely that there will be some significant change to the theory, but "supplanted" is not quite the right word. Any new theory has to take into account the data that has been collected thus far. As more and more data seems to support the consensus view of anthropogenic climate change, it becomes less likely that the current theory will be replaced by something totally different. |

For example, the global warming potential (GWP) of various man-made chloroflourocarbons (CFC's) range between 1,300 and 9,300 times greater potency as greenhouse gases than CO2. Methane has a GWP of about 21 and nitrous oxide a GWP of about 310. Comparing greenhouse gases by strict concentration only, the total human component is somewhere between 0.1% and 0.2%, depending on whose numbers you use. Adjusted for GWP, the total human contribution to Earth's overall greenhouse effect is about 0.28%." So, the 18.8 oz of R-12 in my 1973 Mercedes 220D's really-great-working air conditioner is NOT going to depopulate the planet.
