Since the theory of man-made global warming has become such a powerful political force,the debates around the global warming can’t stop! Quite like the one between Former Speaker of the House and possible Republican presidential candidate Newt Gingrich of Georgia and 2004 Democrat presidential nominee Senator John Kerry of Massachusetts, you will say.
Claude Allegre, one of France’s leading socialists and among her most celebrated scientists, was among the first to sound the alarm about the dangers of global warming.”By burning fossil fuels, man increased the concentration of carbon dioxide in the atmosphere which, for example, has raised the global mean temperature by half a degree in the last century,” Dr. Allegre, a renowned geochemist, wrote 20 years ago in Cles pour la geologie..” Fifteen years ago, Dr. Allegre was among the 1500 prominent scientists who signed “World Scientists’ Warning to Humanity,” a highly publicized letter stressing that global warming’s “potential risks are very great” and demanding a new caring ethic that recognizes the globe’s fragility in order to stave off “spirals of environmental decline, poverty, and unrest, leading to social, economic and environmental collapse.”
Moreover, Astrophysicist Nir Shariv, one of Israel’s top young scientists, describes the logic that led him ( and most everyone else ) to conclude that SUVs, coal plants and other things man-made cause global warming,par example.He has recanted: “Like many others, I was personally sure that CO2 is the bad culprit in the story of global warming. But after carefully digging into the evidence, I realized that things are far more complicated than the story sold to us by many climate scientists or the stories regurgitated by the media.Solar activity can explain a large part of the 20th-century global warming,” he states, particularly because of the evidence that has been accumulating over the past decade of the strong relationship that cosmic- ray flux has on our atmosphere. So much evidence has by now been amassed, in fact, that “it is unlikely that the solar climate does not exist.”
Well,can we talk about a long-time change in solar irradiance? As Dr. Habibullo Abdussamatov at Saint Petersburg’s Pulkovo Astronomical Observatory observed “Mars has global warming, but without a greenhouse and without the participation of Martians.” The sun’s increased irradiance over the last century, not C02 emissions, is responsible for the global warming we’re seeing, says the celebrated scientist, and this solar irradiance also explains the great volume of C02 emissions.Because of the scientific significance of this period of global cooling that we’re about to enter, the Russian and Ukrainian space agencies, under Dr. Abdussamatov’s leadership, have launched a joint project to determine the time and extent of the global cooling at mid-century. The project, dubbed Astrometry and given priority space-experiment status on the Russian portion of the International Space Station, will marshal the resources of spacecraft manufacturer Energia, several Russian research and production centers, and the main observatory of Ukraine’s Academy of Sciences. By late next year, scientific equipment will have been installed in a space-station module and by early 2009, Dr. Abdussamatov’s space team will be conducting a regular survey of the sun.
“If you look back into the sun’s past, you find that we live in a period of abnormally high solar activity,” is Dr. Weiss’s state. The professor of astrophysics at the University of Cambridge, believes that the warming trend in Earth’s climate is caused by greenhouse gases produced by human activity, and that the effect of a potential future reduction in solar activity would not reverse or cancel out that trend, but might have a small effect in mitigating it. He has held these views for several years. Incorrect information appeared in a column in the Financial Post on Feb. 2. The National Post withdraws any allegation that Dr. Weiss is a global warming “denier” and regrets the embarrassment caused him by the Feb. 2 column and a further column on Feb. 9.
