Carbon dating confirms much and plays a large part of the techniques used to arrive at such widely accepted and mainstream taught scientific facts. Again, we know what the climate was, but not conclusively how it got that way. It's called weather. Weather coupled with other events. There are many good theories, but that's all they are. Changing the topic from one of you learning how global warming is defined, studied, and confirmed to another serves only to solidify your pain in ebing incorrect. Like I told Frank, science can tell us that, for instance, it was once tropical in Montana, and that Glaciers covered much of the northern United States during different time periods. This proves that the earth's climate has vacillated in a fairly wide range. But what this DOESN'T tell us is how much of the current global warming cycle can be attributed to natural cyclic climatic changes, and how much of it is a direct result of man made pollution. Sure it can, and does. The amount of many chemical releases in the atmosphere are man made. Many are not man made. Exactly, which is why it is extremely difficult to make a positive determination as to the percentage of man's contribution to the total amount of global warming. It's not difficult at all. I just taught you that the concentration of such gases, such as methane gas, is but a single method by which is measured. Some are both. However, science has methods of measuring each,,including natural occurring vs. manmade chemicals,,,such as methane gases. Yes, and that "science" is in much dispute right now as there are many scientists who do not accept the findings of others as conclusive. There are still many assumptions being made. Not regarding global warming. Twenty years ago, yes..today, it is widely accepted and taught mainstream. Without a point of reference, it is extremely difficult to positively determine how much we are changing the climate. The point of reference is the richness/ concentration of the gas. Which we cannot positively ascertain because we do not know how much of that gas truly came as a result of man-made pollution versus that which is naturally occurring. But we do. One large volcano eruption, for instance, can drastically effect the concentration of methane .gasses in the atmosphere. Yes, but it does not dilute or enrich what is already there, it simply adds quantity to one or the other. Such an example is very easily taken into consideration and calculations allow for the exact molecular configuration when determining such factors. This is done by the precise and absolute measuremtn of related contributions, such as time of eruption, length of eruption, velocity of eruption, etc., etc. _ An example can be the amount of methane in a predetermined air sample. Higher concentrations of the gas can be attributed to manmade releases and emissions. Or a volcano eruption. Methane gas does not have a "tag" which says "man made" or natural. We can only measure the total concentration. =A0 Which is the exact manner in which to tell man-made from natural. =A0It's elementary for anyone with a fair retainment value that took college science classes. Since you called it "elementary", it's obvious that you've never studied it, as it is far too complex a process to be called "elementary". Umm,,no. Go back and reread just what I called "elementary"... not what you felt the need to misrepresent here. By attempting to make this issue simpler than it really is, you also disparage the scientists who do this for a living. It is very simple for anyone who has ever taken college science classes, but gases are introduced in elementary school science. _ Chloroflourocarbons released by the burning of fossil fuels is directly linked to global warming. No argument. But you can't positively determine the rate of global warming that might still be occurring if we suddenly stopped using fossil fuels today. Sure you can. One measures the rate of speed the studied glaciers melt. If they suddenly stopped melting and began growing, the figured equations and calculations are all that's left to give you the answer you seek. Global warming was proved by the continual shrinkage of the polar ice cap confirmed by 24-7 high tech monitoring of such. Villages that reside in the frozen tundra watch their mountains of ice shrink each year. How much of that shrinkage would still be occurring without man made pollution? As you referred, the climate is thought to adhere to cycles, When the cycles suddenly deviate substantially from the norm, it's dedeucedly dedeucedly? Do you mean deductively? Ha,,no I meant "deucedly", as in wickedly confirmed. I was watching the penguin on the Dudley Doright cartoons and my fingers did their own thing.. And you chastise MY vocabulary and grammar....... Huge difference. I admit my mistakes whereas you scream bloody murder or try to ignore yours because of the pain they cause you. _ decided and accepted that something is amiss. First of all, there is no "norm" when it comes to clim`atic shifts. When "deviation from the norm" is used in such a reference, it means deviation from the usual patterns. -You- were first to claim weather patterns in his topic, now you again, self-contradict yourself. Many of those shifts occurred as the direct result of an external random event, such as the asteroid strike which is generally the current accepted theory for precipitating the extinction of the dinosaurs at the end of the Cretaceous period. Not any more. Perhaps when you were i grammar school, but the most compelling andgenerally accepted theory now is they simply died out. The meteor that caused the ice age that was originally thought to have brought about the extinction of such creatures is now believed to have occured many, many years after the dinosaurs have already become extinct. There are other craters all over the planet, as evidence of other such strikes. Yea,,and if you ever were west of the Mississippi, you would have undoubtedly had the chance to see one. There is also evidence of large volcano eruptions, ..in 'patterns' of eras of high activity. which can spew enough particulate matter into the atmosphere, that an "ice age" would likely result. And did. The climatic shifts which occur between these significant events is likely only the result of climatic balance or a normalization from the extremes caused by the random external events. It's also conceivable that over the last billion years, that the solar energy output from the sun could have deviated to some degree as well, which can certainly affect surface temperature here. It's not conceivable, it's been proved the sun's harmful rays have intensified over time. This is because of the damage in the ozone layer. This is called global warming. Again, you come full circle. My work on this topic is done. |

Dave "Sandbagger" The intellicast links aren't compatible with webtv. Here are a few for you, concerning your errors. Note the date on my references. They are last word on the subject. Of course, if you have data confirmed since by a verifiable source, feel free to post it.... http://www.latimes.com/news/nationwo...may20,1,60065= 96.story?ctrack=3D1&cset=3Dtrue =A0 THE WORLD As Climate Shifts, Antarctic Ice Sheet Is Growing Increased snowfall on the central icecap partly offsets effects of melting glaciers, researchers say. By Robert Lee Hotz, Times Staff Writer As glaciers from Greenland to Kilimanjaro recede at record rates, the central icecap of Antarctica has been steadily growing for 11 years, partially offsetting the rise in seas from the melt waters of global warming, researchers said Thursday. The vast East Antarctic Ice Sheet =97 a 2-mile-thick wasteland larger than Australia, drier than the Sahara and as cold as a Martian spring =97 increased in mass every year from 1992 to 2003 because of additional annual snowfall, an analysis of satellite radar measurements showed. "It is an effect that has been predicted as a likely result of climate change," said David Vaughan, an independent expert on the ice sheets at the British Antarctic Survey in Cambridge, England. In a region known for the lowest temperatures recorded on Earth, it normally is too cold for snow to form across the 2.7 million square miles of the ice sheet. Any additional annual snowfall in East Antarctica, therefore, is almost certainly attributable to warmer temperatures, four experts on Antarctica said. "As the atmosphere warms, it should hold more moisture," said climatologist Joseph R. McConnell at the Desert Research Institute in Reno, who helped conduct the study. "In East Antarctica, that means there should be more snowfall." The additional snowfall is enough to account for 45 billion tons of water added to the ice sheet every year, just about equal to the amount of water flowing annually into the ocean from the melting Greenland icecap, the scientists reported in research published online Thursday by the journal Science. Rising sea level, which could swamp many coastal and island communities, is considered one of the most serious potential consequences of global warming, according to the most recent assessment by the United Nations' Intergovernmental Panel on Climate Change. Overall, sea level is estimated to be rising by 1.8 millimeters a year worldwide because of the expansion of warming water and the added outwash from melting glaciers in Greenland, Alaska, tropical highlands and some areas of Antarctica. Every millimeter of increased sea level corresponds to about 350 billion tons of water a year. The growth in the East Antarctic icecap is enough to slow sea-level rise by a fraction of that =97 about 0.12 millimeter a year =97 the researchers reported. All told, the fresh water locked up in the ice of East Antarctica is enough to raise the level of the oceans by about 196 feet, experts said. If it continues to grow as expected, the ice sheet could buffer some, but not all, of the effects of anticipated sea-level rise for much of the coming century, the researchers said. "It is the only large body of ice absorbing sea level rise, not contributing to it," said Curt H. Davis, a radar mapping expert at the University of Missouri-Columbia, who led the research team. The researchers based their conclusions on an analysis of 347 million radar altimeter measurements made by the European Space Agency's ERS-1 and ERS-2 satellites from June 1992 to May 2003. They determined that the icecap appeared to be thickening at the rate of 1.8 centimeters every year. The ice is thinning in West Antarctica and other regions of the continent. "The changes in the ice look like those expected for a warming world," said glaciologist Richard Alley at Pennsylvania State University. "The new result in no way disproves global warming; if anything, the new result supports global warming." _ One more for the road.... http://pqasb.pqarchiver.com/sptimes/...b328640589641= 0dab46b4c26c9fe&did=3D842083261&FMT=3DFT&FMTS=3DFT &date=3DMay+19%2C+2005&a= uthor=3D&printformat=3D&desc=3DReport%3A+Iraq+asse ssment+bleaker http://pqasb.pqarchiver.com/sptimes/...b328640589641= 0dab46b4c26c9fe&did=3D842083261&FMT=3DFT&FMTS=3DFT &date=3DMay+19%2C+2005&a= uthor=3D&printformat=3D&desc=3DReport%3A+Iraq+asse ssment+bleaker Spin it again and tell us how Iraq is getting better, Dave. |
