I think a healthy debate of all viewpoints is needed before making draconian political decisions that could affect all of us. Appeals to authority do not cut water as far as real science is concerned. You could find almost the same group of organizations opposed to continental drift in the 1960's, yet they were dead wrong. Order the book "The Role of the Sun in Climate Change", Oxford University Press see http://www.amazon.com/Role-Sun-Climate-Change/dp/019509414X/ref=pd_bbs_s r_1/103-4233475-8101463?ie=UTF8&s=books&qid=1179775211&sr=8-1 None of the CO2 driven advocates of Global Warming can explain the Medieval Warming Period see http://www.skepticism.net/articles/2002/000033.html and http://www.whoi.edu/page.do?pid=12455&tid=282&cid=9986 and http://www.whoi.edu/page.do?pid=12455&tid=441&cid=8722&ct=61&article=384 2 Get out your Norton Star Atlas and look at a comparison of sunspot activity for the 1800's vs. the 1900's. Finally there is strong evidence particulate emissions have a cooling effect on climate. See: http://www.stanfordreview.org/Archive/Volume_XXXVI/Issue_8/Opinions/opin ions1.shtml The author of this article fails to discuss the large amount of particulate pollution now coming from China and they are also proponents of CO2 as a the major factor in global warming. See a list of all the proponents of CO2 as the major factor who have changed their positions in the last few years: http://epw.senate.gov/public/index.cfm?FuseAction=PressRoom.Blogs&Conten tRecord_id=927B9303-802A-23AD-494B-DCCB00B51A12 http://newsbusters.org/node/12793 Finally, a recent article in Energy and Environment, German researcher Ernst-Georg Beck, shows that the pre-industrial level is some 50 ppm higher than the level used by computer models that produce all future climate predictions. Completely at odds with the smoothly increasing levels found in the ice core records, Beck concludes, "Since 1812, the CO2 concentration in northern hemispheric air has fluctuated, exhibiting three high level maxima around 1825, 1857 and 1942, the latter showing more than 400 ppm."

Sorry for the delay in responding. The only remotely astronomical connection to the issue of Global Warming comes from a handful of folks who say that rather than being the result of human activity, the global climate change we're currently experiencing is caused by a change in solar output. That's just not so - it's been investigated thoroughly. Natural causes (solar output, volcanoes, etc.) can account for only a small fraction of the climate change we're experiencing ("Climate Change Science Moves from Proof to Prevention" Scientific American, Feb 1, 2007). Citing an opinion piece by a right-wing blowhard in a Canadian newspaper does not mean the decades of work by thousands of working scientists who've published their work in peer-reviewed professional journals has somehow been disproved. Our sense of "fairness" has been distorted to the point that anyone can say anything, no matter how nonsensical it is, and the press feels obligated to give their ideas equal consideration with the scientific data that professional researchers have labored long and hard to acquire. Remember "Intelligent Design?" The National Academies of Science, the Association for the Advancement of Science, the Intergovernmental Panel on Climate Change, American Meteorology Society and other organizations representing professional climate researchers are unequivocal in their position that the global climate change we're seeing is primarily the result of human activities, and they've got libraries of hard scientific fact to back them up. Professional climate esearchers are finding _more_ evidence, not less, that the majority of the climate change we're seeing around the world is caused by us. Global Warming deniers have been shown the data and they're not letting go of their delusions. What good comes from arguing with them?

I respectfully recommend that we all voluntarily refrain from using this forum for posting articles and opinions on global warming. The internet offers zillions of other places to do that.
