I guess it never occurred to you that this planet is in a constant state of flux on a level that dwarfs mankind's perception. So the ice caps melt? OK, someday the earth cools again and they reform to their previous state. Here's three words of wisdom for you .... Adapt ... improvise ... overcome. It's far more constructive and purposeful than whining about things you can't control. Quite interesting we have no idea of the range of stable conditions which can exist. We have only a tentative idea of the change in the "average" which causes or ends and ice age. Mainly the problem is we really don't know that much about the weather. Our weather guys (like the tool guy) claim great accuracy. But collect seven day forecasts for seven days and see how the prediction for tomorrow is little more than "just like today" which is right 80% of the time because weather tends to remain constant for five day periods. We don't have a fraction of the information needed to predict long term trends. But the few pieces we have are so blown out of proportion that they appear to be dominant. We have no idea what is dominant if anything. We do know life has survived for 4 billion years without any help from intelligence. We know every "dominant" criteria today has been greatly exceeded, higher or lower, in the past. In fact we suffer from the same issue as sci.astro.seti of having only one data point, that point being our current condition without the least knowledge of how they work together if they do or if any of them are critical or dominant or even important. We have no idea if CO2 matters in the least. We know for a fact water vapor is the most important "gas" regulating temperatures is a complex, interactive and poorly understood manner -- poorly understood in a global sense for certain and often in a local sense. We have a good indication Greece became markedly more arid around 1200 BC and we note civilization increased afterwards. Post hoc ergo propter hoc is false but early Greek civilization did not collapse because of it.

Just because we don't understand the weather does not mean that we are not responsible for some of its changes... That is saying every wild assertion is true until a negative is proven. That is nonsense. Those making the assertion must establish it as a fact by presentation of physical evidence. That must pass rigorous application of the criteria of the scientific method. And in science one exception means the theory is bull.

When you believers present physical evidence in support of your position many people including myself will critically examine it. Here there are two possibilities. The first is you have knowledge of such evidence, you will present it and defend it. That will lead to an interesting exchange. The second is you know nothing but what you have read, you are unable to present and defend it and you are only reciting what you have chosen to believe. That means you can only honestly saying anything on the subject by attributing it to the person from whom you got it as you know nothing yourself. That will be a very boring exchange of acrimony. -- If it is foolish to fight duels for personal honor why is it a wise to fight wars for national honor? -- The Iron Webmaster, 3333 |

It's generally accepted as being a scam, a con game, and a stupid greenie religion in some political religions, and the cause of all evil in some greenie religions. As religions mostly appeal to parrots, both religions are parroted widely and eagerly. This got crossposted here because of the single data point problem which also faces SETI. Climate change due to human activity is generally accepted as being a reality by the vast majority of the scientific community, regardless of their political affiliations, although there's no agreement nor sufficient knowlegde about the extent, the danger, and the effects. Scientists are not immune to political fads. The very fact that the "vast majority" agree when real scientists do not offer public opinions on subjects outside their professional expertise shows it is political. The vast majority of biologists do not have independent opinions on the big bang they only know the common opinion in astrophysics. Any suggestion of any vast majority can only be of what the professional community in that field holds. It cannot be a personal knowledge statement. In fact the only opinions worth reviewing are those of people specializing in predictive global climatology. The field sort of exists. Getting back to the single data point issue, so far it has had no successes as it is too new, seriously barely ten years old. It lacks elementary information in matters which are currently consider crucial. CO2 is considered crucial. But fully one third of the carbon cycle is unknown; completely unaccounted for by anyone. I myself do not consider it reasonable to identify human activity as the cause of a few parts per thousand increase in atmospheric CO2 when 1/3 of the carbon cycle is unknown. I expect a bit more. -- You go to war with what you have only if you have to go to war. -- The Iron Webmaster, 3317 |

[....] I myself do not consider it reasonable to identify human activity as the cause of a few parts per thousand increase in atmospheric CO2 when 1/3 of the carbon cycle is unknown. I expect a bit more. You would probably not be convinced that we have any influence on the climate even if Florida (where you live..) would be hit harder and harder by stronger and stronger tornado's. I extract from your statement that you DO believe that CO2 levels in the atmosphere went up. That's at least something. Yes. They went up from 275ppm to 375ppm in a 50 year time period. I'm not sure if you attribute this increase of CO2 to human causes. Maybe some facts would help ? I'll keep it simple : Over the past 5 million years, we know from ice-core data that CO2 levels in the atmosphere varied. From 200ppm during the ice-ages to about 275ppm in the warm periods. In 1950 it still was about 275ppm. Now, it is 375ppm. And going up. We have no record of it ever being so high (at least not for a very long time in the past). The increase is (in mass) a bit more than the total mass of CO2 pumped into the atmosphere by us buring fossil fuel since 1950. The remainder (of excess CO2) can be explained by the destruction of forests around the world (less CO2 absorbed by forests). So the 100ppm is what we put out into the atmosphere. It seems that it is still where we put it. It was not magically absorbed by some other process on the planet... If you want, I can come up with all the references and to these numbers, but I'm not sure if that helps at all, since you seem to be convinced that all this is still a belief system. For the same reason, I don't want to go for the next step (that there is a strong correlation between CO2 in the atmosphere and the global temperature), unless you want me to. I recommend that you read the September edition of National Geographic. The entire article edition is devoted to global warming. If you want to, you can ignore the stories of the ecological damage that the current 1 degree increase in temperature already caused, and skip the global devestation that are predicted by even the most conservative models of warming available. You can also skip the section of the risks of global warming possibly causing harsh cold winters in Northern Europe, because such local effects are indeed very hard to predict at this point. Just read the section that deals with CO2 and temperature increases. Rob |

Any suggestion of any vast majority can only be of what the professional community in that field holds. It cannot be a personal knowledge statement. Just for the record: there is no distinction between "scientists" and "real scientists". They are the same. For the record of the 104 scientists who signed the first UN global warming declaration 102 of them were political scientists. I don't know if the ratio has changed since then. Also I do question the credentials of any scientist who gives authoritative opinions in fields other than his own. That is unprofessional. If I talk about the Big Bang and about the vast majority of scientists supporting this theory, I'm not talking about medical scientists. If I talk about global climate change and the vast majority of scientists supporting the theory that there's a significant effect from human activity on it, I'm not talking about historians, sociologists or dentists. If you are talking about what you claim then you are talking about a bare handful of climatologists who have been in the business of making predictions for barely ten years. Note that is not long enough to have any track record. In fact the only opinions worth reviewing are those of people specializing in predictive global climatology. The field sort of exists.

I myself do not consider it reasonable to identify human activity as the cause of a few parts per thousand increase in atmospheric CO2 when 1/3 of the carbon cycle is unknown. I expect a bit more. Contrary to your beliefs data about the effect on climate and weather due to contribution from a variety of human activities, from emissions like greenhouse gases and ozon depleting gases to various activities like deforestation, are _neither_ speculation, _nor_ unknown, unidentified, or insignificant. Then of course you will direct my attention to an explanation of 100% of the carbon cycle. I see no reason to blithely ignore the completely unknown 1/3. I point out the majority of the temperature increase in the last century was in the first half. Was CO2 higher between 1900 and 1950 than between 1950 and 2000? If not, please explain. Why and how did CO2 vanish from the atmosphere during the Ice Ages? Why and how did it decrease during the little ice age a few centuries ago? But if there has not been a one to one corelation between CO2 and temperature before now, why now? Since when has it been legitimate to directly relate heat and temperature without controlling every other variable? The data exist, and are established; information is neither lacking nor inconclusive. The quantity of data is growing each day. The problem is not that the data are not available, but what _precise_ effects this human contribution on climate will have over the time coming. The mere assertion of existence does not indicate existence. But let me ask you, are you in climatology? Have you personally reviewed the data and confirmed it valid? Have you personally or have your collegues actually utilized this data in making these predictions? If your answers are yes, can you explain why most of the temperature increase was in the first half of the last century? If CO2 is so important, it must have vanished during the real ice ages and drastically decreased during the little ice age a few centuries ago. But if those events are to be explained by handwaving other more important factors why are those factors not working today? What do you make of the recent paper reanalyzing the CO2 data of the 19th and early 20th century and finding the single paper which made the claim of an increase was flawed in that the conclusion is caused by the selected and rejected measurements? Again: not the absence of the facts is the problem, but the use or neglect of these facts to support political religions. However I guess neither you nor those "greenies" you so abhor are very interested in changing or adapting religions. Religion and facts aren't particularly going along well together. I look at the "we're running out of oil" crowd and the "we're melting" crowd and it appears the former is ahead so we will run out of oil before we melt. So you folks can stop worrying. If we take the CO2 increase over time seriously, dropping back to 1900 level burning will get CO2 level back down by 2100. The only proposal taken seriously in public is trading burning rights from developing countries for hard currency resulting in no decrease in emmissions. As Chricton put it, if in 1900 the huge population increase had been known there would have been urgent horse breeding and manure handling programs started. Instead there was only Malthusian gloom and doom. You do remember the food riots in India in the 1970s don't you? Predictions of future disaster have always been with us. And always it has been, this time it WILL happen. And always the predictions have failed and the real problems were always a surprise. -- Nazism must remain evil to keep communism looking good. -- The Iron Webmaster, 3330 |

Perhaps this is the effect that so far has always killed off any rapidly advancing civilisations. This is one example where the politicians may yet kill us all. Regards, Martin -- ---------- OS?
