The evidence against anthropogenic global warming (Page 24/600) fierobear OCT 18, 03:29 PM If CO2 can force climate changes, here is a case for natural causes and variability over manmade sources: A role for atmospheric CO2 in preindustrial climate forcing (pdf file) (excerpt) Concluding Remarks A coherent scenario explaining preindustrial atmospheric CO2 changes of the last millennium and their possible temporal link with changes in terrestrial and marine carbon uptake or release still needs to be established. Reconstructed multidecadal changes are not as prominent as man-made CO2 increases since the onset of industrialization. Yet it seems obvious that a dynamic CO2 regime with fluctuations of up to 34 ppmv implies that CO2 can no longer be discarded as a forcing factor of preindustrial air-temperature changes. The results of our study therefore underscore the need to understand anthropogenic global warming within the context of rates and amplitudes of natural CO2 variability of the last millennium. A stomata-based CO2 record may provide an important observational constraint on the sensitivity of climate models. Arns85GT OCT 18, 07:34 PM They still have it backwards. The variations in the Sun's output (first and foremost) and the spewing of carbon bits into the atmosphere by volcanoes are the main reasons for heating and cooling of the earth. CO2 to the result of higher plant and animal life and is a result of increased heat from the Sun. Emissions don't produce heat. They filter the rays of the Sun. This junk science of attributing CO2 to global warming is just pure error.

But the reason I posted the above paper is that CO2 and temperature varied much more before the industrial revolution.

Maybe it is like Ghost busters, all the hate and negative feelings in the world are depleting ozone!!! fierobear OCT 20, 02:55 PM Good article Lorne Gunter: Thirty years of warmer temperatures go poof Posted: October 20, 2008, 10:26 AM by Kelly McParland Lorne Gunter, Ful Comment In early September, I began noticing a string of news stories about scientists rejecting the orthodoxy on global warming. Actually, it was more like a string of guest columns and long letters to the editor since it is hard for skeptical scientists to get published in the cabal of climate journals now controlled by the Great Sanhedrin of the environmental movement. Still, the number of climate change skeptics is growing rapidly. Because a funny thing is happening to global temperatures -- they're going down, not up. On the same day (Sept. 5) that areas of southern Brazil were recording one of their latest winter snowfalls ever and entering what turned out to be their coldest September in a century, Brazilian meteorologist Eugenio Hackbart explained that extreme cold or snowfall events in his country have always been tied to "a negative PDO" or Pacific Decadal Oscillation. Positive PDOs -- El Ninos -- produce above-average temperatures in South America while negative ones -- La Ninas -- produce below average ones. Dr. Hackbart also pointed out that periods of solar inactivity known as "solar minimums" magnify cold spells on his continent. So, given that August was the first month since 1913 in which no sunspot activity was recorded -- none -- and during which solar winds were at a 50-year low, he was not surprised that Brazilians were suffering (for them) a brutal cold snap. "This is no coincidence," he said as he scoffed at the notion that manmade carbon emissions had more impact than the sun and oceans on global climate. Also in September, American Craig Loehle, a scientist who conducts computer modelling on global climate change, confirmed his earlier findings that the so-called Medieval Warm Period (MWP) of about 1,000 years ago did in fact exist and was even warmer than 20th-century temperatures. Prior to the past decade of climate hysteria and Kyoto hype, the MWP was a given in the scientific community. Several hundred studies of tree rings, lake and ocean floor sediment, ice cores and early written records of weather -- even harvest totals and censuses --confirmed that the period from 800 AD to 1300 AD was unusually warm, particularly in Northern Europe. But in order to prove the climate scaremongers' claim that 20th-century warming had been dangerous and unprecedented -- a result of human, not natural factors -- the MWP had to be made to disappear. So studies such as Michael Mann's "hockey stick," in which there is no MWP and global temperatures rise gradually until they jump up in the industrial age, have been adopted by the UN as proof that recent climate change necessitates a reordering of human economies and societies. Dr. Loehle's work helps end this deception. Don Easterbrook, a geologist at Western Washington University, says, "It's practically a slam dunk that we are in for about 30 years of global cooling," as the sun enters a particularly inactive phase. His examination of warming and cooling trends over the past four centuries shows an "almost exact correlation" between climate fluctuations and solar energy received on Earth, while showing almost "no correlation at all with CO2." An analytical chemist who works in spectroscopy and atmospheric sensing, Michael J. Myers of Hilton Head, S. C., declared, "Man-made global warming is junk science," explaining that worldwide manmade CO2 emission each year "equals about 0.0168% of the atmosphere's CO2 concentration ... This results in a 0.00064% increase in the absorption of the sun's radiation. This is an insignificantly small number." Other international scientists have called the manmade warming theory a "hoax," a "fraud" and simply "not credible." While not stooping to such name-calling, weather-satellite scientists David Douglass of the University of Rochester and John Christy of the University of Alabama at Huntsville nonetheless dealt the True Believers a devastating blow last month. For nearly 30 years, Professor Christy has been in charge of NASA's eight weather satellites that take more than 300,000 temperature readings daily around the globe. In a paper co-written with Dr. Douglass, he concludes that while manmade emissions may be having a slight impact, "variations in global temperatures since 1978 ... cannot be attributed to carbon dioxide." Moreover, while the chart below was not produced by Douglass and Christy, it was produced using their data and it clearly shows that in the past four years -- the period corresponding to reduced solar activity -- all of the rise in global temperatures since 1979 has disappeared. It may be that more global warming doubters are surfacing because there just isn't any global warming. lgunter@shaw.ca National Post Toddster OCT 20, 04:14 PM Just read an article in the Epoch Times about a new book called The Deniers: The World-Renowned Scientists Who Stood Up Against Global Warming Hysteria, Political Persecution, and Fraund by Solomon.

Yup. Better buy it, quick like! In fact, you'd better buy all books that debunk global bullshit, because they'll be burned or rewritten by the Marxists.
