Neil Gould wrote: The same cannot be said about an ecosystem that will no longer support human life. Please cite one legit source that says the current Global warming trend is going to bring about an ecosystem that will no longer support human life. You can easily find such sources if you're genuinely interested and not simply wishing to dismiss all who disagree with you as illigitimate. As a starting point, you may wish to look through the last couple of years' Scientific American as an easily consumable digest of the issues at hand and that isn't radical in its commentary. If humans are causing GW then with the exception of us doing something that causes a VERY rapid and overwhelmingly great change (like popping off several 1000 nukes) there isn't anything we can do to cause that sort of change because long before enough had been done to kill everyone enough would be done to kill enough of us to stop the human caused GW. I'm not one to claim that humans are _causing_ GW. Given the historic record of temperatures there is no doubt that human activities are a contributing factor. As I see it, we're aggravating the trend, so the question becomes, what are the consequences of that? Neil |

One thing that has been well established about the cycles is: "It was now clear that not only the most obvious feedback, but also the most momentous one, was the connection between global temperature and greenhouse gas levels. Relatively straightforward analysis of the data showed that a doubled level of CO2 had always gone along with a rise of a few degrees in global temperature. It was a striking verification, with entirely independent methods and data, of what computer models had been predicting for the planet's greenhouse future." http://www.aip.org/history/climate/cycles.htm at the very end. So there's a strong link between rises in temperature and the greenhouse gas CO2. From one of the websites you so blithely blew off: "The atmospheric levels of the greenhouse gas carbon dioxide, have increased since pre-industrial times from 280 part per million (ppm) to 377.5 ppm (2004 Carbon Dioxide Information Analysis Center), a 34% increase. Carbon dioxide concentrations in the atmosphere are the highest in 650,000 years. Carbon dioxide is a by-product of the burning of fossil fuels, such as gasoline in an automobile or coal in a power plant generating electricity." First, I've done some of my own all-too-brief reading of past studies and did scan the references you gave. Secondly, I've known for a couple years of at least two groups that found that over tectonic time scales (i.e. on the order of hundreds of millions of years) atmospheric CO2 did _not_ appear to covary with climatic temperatures. They state: "The resulting CO2 signal exhibits no systematic correspondence with the geologic record of climatic variations at tectonic time scales." [1] "Research on systems ranging in age from 440 million years to the present suggests that atmospheric CO2 levels have been as much as 16 to 18 times higher at different times in the ancient past than they are today. However, surface temperatures of ancient, low altitude, tropical sites appear to have varied only from about 23 degrees C to 32 degrees C. Interestingly, these temperatures do not seem to covary directly with ancient atmospheric CO2 pressures."[2] [1] http://www.pnas.org/cgi/content/full/99/7/4167 (or: http://www.pubmedcentral.nih.gov/art...i?artid=123620 ) [2] http://www.geology.smu.edu/~vineyard/yapp.html Are you so confident that all the modern recorded changes are due solely to ice-age warming that you're willing to dismiss it all as "fraud" the way Barrow did? (I think not, but you did chime in on his post where he said that.) I am confident of nothing - I'm just going with what seems most probable given my limited knowledge of the research and underlying physics. I'm _inclined_ to believe CO2 is a factor in present climate change in spite of the research quoted above. I just don't think you should be so confident either. I don't agree with Barrow's claim that it is all a fraud. Fraud happens in science, but if someone has a specific claim, it is up to them to make their case. Since it is Barrow's claim and not mine, it is up to him to make his case. There is also something important missing from that graph - can you guess what it is? Aside from full labeling of the axis and the nature of the graph, the absolute values of the temperatures can only be guessed at - but again, the wiki entry gives a comparison of those in the text, along with the widely accepted conclusion that human activity probably is contributing to, or possibly is totally causing, the temperature rise. What is missing is the error bars. The graph purports to show "Global Temperature Anomaly" but since it relies on a finite (and time-and-space-varying) set of observation points, it should be showing the error range. After all, a single observation is typically representative of a large area - it should not be taken as _the_ average. Furthermore one has to include calibration errors. P.S. After writing the above I went back to the wikipedia entry and following the links to the original graphs - which fortunately include the error bars I would expect (so even Wikipedia managed to include a questionable graph - yet _another_ reason to avoid secondary sources): http://hadobs.metoffice.com/hadcrut3...Bsh/index.html |

A mistake except I ran into someone i knew there who helped me wade through the literally hundreds of k00ks posting there to get some good info for both sides of the argument. Keeping in mind that I was trying to shore up my postion, but at the same time was lookin gfor cogent arguments agin, i nearly went mad trying to make sense of it all. Anyhow, the info that I came up with in the end, was this. The SUV drivers can tear it apart, use it for canary droppings or do what you like. you won't be convinced of anything anyway, but it does have the best info that several days worth of research on my behalf could produce. Wanna argue? Write a leter to the NY times or these guys. http://www.realclimate.org/index.php...turated-gassy- argument/ This article adressed just about every argument I saw that was worthy of the title ( I ignored crap like "well, you'd a thunk peeple'd be happy about longer summers" and "Cows make more greenhouse gas than cars") Bertie |
